Best SaaS Starter Kits Ranked 2026: 8 Kits Compared Across 15 Criteria

Every SaaS Starter Has a Hidden Cost They Don't Advertise

The headline price is easy to compare. $199 for Shipfast. $299 for Supastarter. $149 for Makerkit. Free for T3 Stack. Free for Epic Stack.

What they don't show you upfront: the mandatory SaaS services they depend on, the features that look complete until you try to ship them, and the architectural decisions that become expensive to change six months later.

This ranking covers eight SaaS starter kits evaluated across fifteen criteria — the same criteria that matter when you are about to bet your next product on a foundation. We score each kit on auth depth, billing integration, documentation quality, community size, and the costs you will not see until you are already deep into development.

TL;DR

Supastarter is the most complete commercial SaaS starter for B2B products. Multi-tenancy, RBAC, five payment providers, background jobs, file storage, i18n, and a full admin panel are all production-ready. The price and complexity are higher, but no other commercial starter handles B2B SaaS requirements as thoroughly.

Shipfast is the best option for solo founders validating a B2C idea. It is lean, well-documented, and has the most active community of any commercial starter. Setup to deployed MVP in under two days.

T3 Stack (free) is the best foundation if you enjoy building infrastructure and want a fully custom SaaS. You will spend 6–8 weeks building what commercial starters include, but you own every decision.

Epic Stack (free) is the best free full-stack boilerplate with the most comprehensive defaults: strict TypeScript, Playwright testing, Fly.io deployment, and a security model few commercial starters match.

Key Takeaways

• No starter is best for every use case. Multi-tenancy requirements alone eliminate Shipfast and Epic Stack from consideration. Non-Stripe payment providers eliminate Shipfast from international SaaS.
• Hidden costs compound. Most commercial starters require Stripe, Resend or Postmark, Supabase or Neon, and often Vercel. The monthly mandatory services cost $30–80/month at launch even with free tiers.
• Documentation quality predicts how fast you can ship. Starters with incomplete or outdated docs create support burdens. Shipfast and Supastarter have the strongest documentation among commercial options.
• Community size determines how fast you get unstuck. Shipfast's 5,000+ maker Discord is the largest active community around any SaaS starter.
• TypeScript strictness varies enormously. T3 Stack and Epic Stack enforce strict TypeScript. Most commercial starters use loose TypeScript that lets type errors slide.
• Testing is an afterthought in most commercial starters. Epic Stack ships with Playwright, Vitest, and MSW by default. Most others ship with no tests or minimal unit test coverage.

Deep Dive: Auth Depth

Auth is the hardest infrastructure problem to retrofit. Getting it wrong in the boilerplate means a major rewrite later.

Shipfast

NextAuth.js pre-configured with Google, GitHub, Twitter, Discord, and Magic Link. Email/password works out of the box. Protected routes, session middleware, and getServerSession patterns are already wired.

What it lacks: No two-factor authentication (TOTP). No passkeys. No RBAC. No organization-scoped sessions. Fine for individual user accounts; not adequate for multi-user B2B SaaS without significant additions.

Supastarter

better-auth with the most complete feature set of any starter:

• OAuth (any better-auth provider: Google, GitHub, Discord, Apple, and more)
• Magic links
• Email/password with email verification
• Two-factor authentication (TOTP + backup codes)
• Passkeys (WebAuthn)
• Organization sessions — the session carries org membership, user role, and permissions
• RBAC — roles are defined per-organization, permissions are checked per-route

For B2B SaaS, better-auth's organization-aware session model eliminates a common retrofitting problem: adding org context to an auth system that was designed for individual users.

Epic Stack

Custom cookie-based authentication built from scratch with Argon2 password hashing. No third-party auth library dependency.

What this means in practice: The Epic Stack's auth is more auditable and more portable than NextAuth-based solutions. There are no breaking NextAuth upgrades to manage, no provider-specific quirks to work around. The trade-off is that adding OAuth providers requires more manual work.

Makerkit

Supabase Auth handles all auth. This includes OAuth (40+ providers), magic links, email/password, and MFA (TOTP). Row-level security (RLS) in Supabase handles authorization at the database level — a fundamentally different model than application-level RBAC.

RLS is more secure (authorization failures result in empty data, not 403 errors) but requires discipline to write correct policies.

---

Deep Dive: Billing Integration

Billing complexity correlates with SaaS business model complexity. B2C SaaS with simple subscriptions needs less. B2B SaaS with per-seat billing, usage metering, and multiple payment regions needs more.

Shipfast

Stripe, configured for:

• Subscription checkout sessions
• Webhook handling (subscription created, updated, cancelled)
• Customer portal (plan changes, cancellation)
• One-time payments

What it lacks: No Lemon Squeezy, no Paddle, no Polar. No per-seat billing. No usage metering. No multi-currency pricing. The Stripe configuration is clean and complete for simple subscriptions; anything beyond that requires custom code.

Supastarter

The most complete billing implementation in any starter:

Payment providers: Stripe, Lemon Squeezy, Polar, Creem, Dodo Payments
Billing models: Per-user, per-seat, flat rate
Portals: Stripe Customer Portal, Lemon Squeezy portal
Webhooks: Full event handling for all providers
Per-org billing: Yes — each organization has its own subscription

Switching payment providers is a configuration change, not a code rewrite. This is valuable for international SaaS — Lemon Squeezy handles EU VAT compliance and handles merchant-of-record responsibilities, which Stripe does not.

Bedrock

Stripe and Paddle supported, with a clean abstraction layer. Paddle is valuable for EU/UK compliance — Paddle acts as the merchant of record, which eliminates the need to register for VAT in each EU country. For SaaS targeting European customers, Paddle's compliance handling is worth more than the billing complexity.

Deep Dive: Hidden Costs

The monthly operational cost of a SaaS starter is rarely discussed upfront. Here is an honest breakdown of mandatory services and their costs at small scale:

Shipfast Mandatory Services

Service	Provider	Free Tier	Paid Starts At
Hosting	Vercel	100GB bandwidth	$20/month (Pro)
Database	Supabase or MongoDB Atlas	500MB / 512MB	$25/month
Email	Resend	3,000 emails/month	$20/month
Payments	Stripe	2.9% + $0.30/txn	Transaction fees only
Monthly at 0 revenue		~$0 (free tiers)
Monthly at 1,000 users		~$45–65/month

Supastarter Mandatory Services

Supastarter's monorepo architecture requires more services:

Service	Provider	Free Tier	Paid Starts At
Hosting	Vercel	100GB bandwidth	$20/month (Pro)
Database	Neon or Supabase	0.5–10GB	$19–25/month
Email	Resend	3,000 emails/month	$20/month
Background jobs	Inngest or Trigger.dev	Generous free tier	$10–30/month
Storage	Supabase Storage or S3	1GB	$0.021/GB
Payments	Stripe	2.9% + $0.30/txn	Transaction fees
Monthly at 0 revenue		~$0 (free tiers)
Monthly at 1,000 users		~$65–100/month

T3 Stack / Epic Stack (DIY)

Free starters have zero mandatory service costs — but you choose all services yourself. A typical T3 Stack production deployment:

Service	Provider	Cost
Hosting	Vercel Free	$0 (or $20/month Pro)
Database	Neon Free	$0 (or $19/month)
Email	Resend Free	$0 (or $20/month)
Auth	NextAuth (included)	$0
Payments	Stripe	2.9% + $0.30/txn
Monthly at launch		~$0

The cost advantage of free starters comes with the development time cost — 6–10 weeks of building infrastructure that commercial starters include.

---

Deep Dive: Documentation Quality

The gap between starters is widest here. Good documentation halves setup time. Bad documentation doubles debugging time.

Shipfast: 9/10

Shipfast has the most thorough documentation of any commercial starter:

• Quick start guide: 15 minutes to first deploy
• Feature-specific guides: Stripe setup, NextAuth config, email templates
• Troubleshooting section with common errors
• Video walkthroughs for complex setup steps
• Active Discord with the author and 5,000+ members answering questions

The documentation is maintained alongside the codebase. When the codebase changes, the docs change.

Supastarter: 9/10

Comprehensive documentation that covers every feature:

• Architecture overview with diagrams
• Step-by-step guides for each payment provider
• Multi-tenancy setup and customization
• Deployment guides for Vercel, Fly.io, and Railway
• API reference for key packages

The monorepo architecture makes the first-run experience more complex, but the documentation anticipates most confusion points.

Makerkit: 7/10

Solid documentation that covers all features, but depth is uneven. Core auth and billing guides are strong. Some edge cases (custom email providers, Remix-specific patterns) require more investigation.

Epic Stack: 8/10

Kent C. Dodds has written extensively about the Epic Stack's design decisions. The README is thorough. The inline code comments explain non-obvious choices. The trade-off: the documentation assumes you understand Remix, TypeScript strict mode, and Fly.io deployment basics.

T3 Stack: 8/10

create-t3-app's documentation is focused on setup rather than feature documentation (since there are no built-in features). The community documentation (Theo's YouTube channel, t3.gg/discord) fills most gaps. The type safety and architecture guidance is excellent.

Next SaaS Starter: 6/10

The starter exists but documentation is minimal. You will spend time reading source code rather than following a guide.

Bedrock: 6/10

Bedrock has reasonable setup documentation but sparse feature guides. The monorepo structure requires understanding the package layout before you can add features effectively.

SaaSBold: 5/10

Documentation covers installation and basic customization. Deeper customization requires reading source code. Community support is limited compared to larger starters.

---

Deep Dive: Database Flexibility

Database choice is one of the hardest decisions to change later. The wrong choice surfaces as performance problems, migration pain, or vendor lock-in after you have a hundred thousand rows.

The PostgreSQL Starters

Supastarter, Makerkit, Bedrock, and Next SaaS Starter all use PostgreSQL. The difference is the ORM and hosting assumptions.

Supastarter supports both Prisma and Drizzle ORM and targets Neon or Supabase for hosting. Neon is serverless PostgreSQL — connections close between requests, connection pooling is built in. This makes Supastarter's database layer naturally suited to serverless deployments on Vercel.

Makerkit is Supabase-native. The schema migrations, RLS policies, and auth are all designed around Supabase. Moving off Supabase is technically possible but architecturally painful — the Supabase Auth dependency affects the user table structure, session model, and RLS policies throughout the application.

Bedrock uses Drizzle ORM with PostgreSQL, without the Supabase dependency. You bring your own PostgreSQL host. This gives maximum flexibility at the cost of not having the Supabase dashboard for database inspection.

T3 Stack: Maximum Flexibility

T3 Stack uses Prisma, which supports:

• PostgreSQL (Neon, Supabase, Railway, any host)
• MySQL (PlanetScale, AWS RDS)
• SQLite (for local dev)
• CockroachDB
• SQL Server

For teams that want to avoid vendor lock-in at the database layer, T3 with Prisma is the most flexible starting point. The trade-off is zero built-in business features.

Epic Stack: SQLite + Turso Multi-Region

The Epic Stack made the unusual decision to use SQLite via Turso (formerly LiteFS) as its production database. This choice is unconventional but deliberate:

• Zero connection overhead — SQLite connections are file-level, no connection pool needed
• Multi-region reads — Turso replicates the database to multiple regions; reads are served from the nearest replica
• Write latency — writes route to the primary region, typically under 100ms globally on Fly.io

The caveat: SQLite works well for most SaaS products but has limitations for workloads with many concurrent writers. For most B2C SaaS at early scale, this is a non-issue.

MongoDB Starters

Shipfast and SaaSBold support MongoDB (via Mongoose or the native MongoDB driver). MongoDB's schemaless model is faster to iterate on in early development, but the lack of foreign key constraints and joins can create data consistency problems at scale.

If you choose Shipfast and anticipate needing relational data, configuring it for Supabase (PostgreSQL) from day one is worth the extra setup time.

Database	Starters	ORM	Multi-region
PostgreSQL	Supastarter, Makerkit, Bedrock, Next SaaS	Prisma/Drizzle	Via Neon/PlanetScale
SQLite	Epic Stack	Prisma	Turso (Fly.io)
Any SQL	T3 Stack	Prisma	Via choice
MongoDB	Shipfast, SaaSBold	Mongoose/native	Via MongoDB Atlas

---

Deep Dive: Testing Setup

Most commercial SaaS starters ship with no tests. This is a deliberate choice — tests add complexity, and solo founder customers often delete them anyway. But for teams shipping production software, test coverage is a make-or-break criterion.

Epic Stack: The Gold Standard

Epic Stack ships with four layers of testing configured and working:

tests/
├── unit/           # Vitest unit tests
├── integration/    # Vitest integration tests (with MSW)
├── e2e/            # Playwright browser tests
└── factories/      # Test data factories

Vitest for unit and integration tests — fast, ESM-native, compatible with the Remix module system.

Playwright for E2E tests — tests run against a real browser. The Epic Stack ships with working E2E tests for auth flows, which are the most error-prone parts of any SaaS.

MSW (Mock Service Worker) — intercepts HTTP requests in tests, making external API calls testable without real credentials.

Test data factories — each model has a factory that generates realistic test data. Writing tests doesn't require manually constructing complex object graphs.

This testing setup is what engineers mean when they say "professional defaults." No other starter ships anything close to this.

Supastarter: Basic Coverage

Supastarter ships with Vitest unit tests for utility functions and some component tests. No E2E tests. No MSW setup. The testing coverage is enough to validate utility logic but not enough to catch regressions in user flows.

Commercial Starters (Shipfast, SaaSBold)

No tests ship with either starter. The assumption is that solo founders ship fast and add tests later. The reality is that "later" often doesn't come until there is a production bug that a test would have caught.

For teams using Shipfast, adding Playwright for E2E testing requires:

1. Installing Playwright
2. Writing fixture files for auth state
3. Writing page object models for key user flows

This is 2-4 hours of setup that the Epic Stack gives you for free.

T3 Stack: You Choose

T3 Stack doesn't ship tests either, but the community tooling is strong. The T3 community has standardized on Vitest for unit tests and Playwright for E2E. create-t3-app doesn't configure either, but the guides for doing so are comprehensive.

---

Deep Dive: UI Components and Design System

The component library choice affects every page you build. Getting stuck with a starter's component choice — or fighting it — is a common source of friction.

Starters Using shadcn/ui

Shipfast, Supastarter, Next SaaS Starter, and Makerkit all use shadcn/ui as their primary component layer. shadcn/ui's copy-paste model means the components become your code — customizable without fighting the library's update cycle.

The benefit for starter kit users: if you use multiple starters across projects, you will recognize the component patterns. The shadcn component API is the closest thing to a standard UI component interface in the React ecosystem.

SaaSBold: Custom UI Kit

SaaSBold ships with a proprietary UI kit with 200+ components including dashboard layouts, marketing sections, and data display components. This is SaaSBold's main selling point — the breadth of pre-built UI is larger than any other starter.

The downside: the custom UI kit creates a fork from the open-source ecosystem. shadcn component integrations, Radix UI primitives, and Tailwind community components don't drop in as cleanly.

Bedrock: shadcn/ui with Strong Defaults

Bedrock uses shadcn/ui with more opinionated configuration than most starters — stricter TypeScript, more complete component coverage, and better monorepo package boundaries for the UI layer. For teams that find most shadcn starters "too bare," Bedrock is closer to production-ready out of the box.

Epic Stack: Minimal UI

Epic Stack ships with basic Tailwind CSS styling and minimal component abstractions. The Epic Stack's focus is on infrastructure (auth, database, testing, deployment) rather than UI polish. Teams that start with Epic Stack typically add shadcn/ui in the first week.

---

Deep Dive: Deployment and DevOps

How you deploy affects your costs, your operational complexity, and how fast you can respond to production issues.

Vercel-Centric Starters

Shipfast, Supastarter, Next SaaS Starter, SaaSBold, and Makerkit are all documented and optimized for Vercel. Key advantages:

• Zero-config deployment — push to main, Vercel builds and deploys
• Preview deployments — every PR gets a unique URL for review
• Edge functions — middleware runs at Vercel's CDN nodes globally
• ISR — pages regenerate in the background without a full redeploy

The cost risk: Vercel's Pro plan is $20/month. At scale, the Vercel bill can grow significantly if you have many team members, high bandwidth, or many function invocations. Teams that hit Vercel's scaling limits mid-growth often have to migrate to self-hosted infrastructure, which is disruptive.

Fly.io Starters

Epic Stack and Makerkit (Remix version) deploy to Fly.io. Fly.io is a VM-based hosting platform that runs your container close to users. Key advantages:

• Persistent connections — long-running WebSocket connections work natively
• Multi-region — deploy the same container to 10+ regions with traffic routing
• Predictable pricing — per-VM pricing, not per-invocation
• SQLite-compatible — file-based databases like Turso work naturally

Fly.io requires more ops knowledge than Vercel. You manage deployments via flyctl, configure regions, and monitor with Fly.io metrics.

Self-Hosted Flexibility (Bedrock, T3 Stack)

Bedrock and T3 Stack can deploy anywhere that runs Node.js. For teams with existing infrastructure (AWS, GCP, on-premise), this matters. A containerized T3 Stack app runs in any Kubernetes cluster or EC2 instance with no Vercel dependency.

---

Deep Dive: Update Frequency and Longevity Risk

You are betting on a foundation for a multi-year product. Is the author likely to maintain it?

Commercial Starters

Starter	Last Major Update	Version	Notes
Shipfast	Jan 2026	3.x	Active, Marc Lou still shipping products
Supastarter	Feb 2026	6.x	Active, Jonas Bröms full-time
Makerkit	Mar 2026	v3	Active, Giancarlo full-time
Bedrock	Dec 2025	2.x	Moderate activity
SaaSBold	Oct 2025	2.x	Slower updates

Risk assessment: Shipfast, Supastarter, and Makerkit are all maintained by founders whose income depends on the product's quality. They have strong incentives to keep the codebase current with Next.js releases, dependency updates, and security patches.

Open-Source Starters

T3 Stack and Epic Stack are community projects. T3 has 28K GitHub stars and corporate interest (Theo's company supports it). Epic Stack has Kent's personal commitment — the risk is that a single maintainer's priorities can shift.

Next SaaS Starter is maintained by Vercel and the shadcn team — arguably the lowest longevity risk in the ecosystem, since Vercel has organizational incentives to keep the starter current.

Rankings by Use Case

Best for Solo Founders (B2C SaaS)

1. Shipfast — fastest setup, best community, clean code, perfect for individual subscriptions
2. Next SaaS Starter — free alternative with Stripe and solid auth, requires more customization
3. Makerkit — more complete than Shipfast for features, higher learning curve

Best for B2B SaaS Teams

1. Supastarter — the only starter with production-ready multi-tenancy, RBAC, and multi-provider billing
2. Makerkit — strong multi-tenancy, Supabase-native, good for Supabase-committed teams
3. Bedrock — monorepo with Paddle support is valuable for EU markets

Best Free Starter

1. Epic Stack — the most complete free boilerplate with the strongest defaults
2. T3 Stack — best type safety foundation, requires building all business features
3. Next SaaS Starter — best free option with billing included

Best for Type Safety

1. T3 Stack — tRPC end-to-end type safety, Zod everywhere, strictest TypeScript defaults
2. Epic Stack — strict TypeScript, full-stack type safety through Remix loader inference
3. Bedrock — strong TypeScript configuration with monorepo package boundaries

---

The Bottom Line

Best overall for B2B SaaS: Supastarter — the only starter that handles multi-tenancy, RBAC, and multi-provider billing without a major rewrite. The higher price and complexity are justified for products where these features are required on day one.

Best overall for solo founders: Shipfast — the most mature, best-documented, and most community-supported commercial starter for B2C SaaS. The $199 price pays for itself in the first week of development.

Best free option: Epic Stack for full-stack rigor, T3 Stack for maximum type safety and flexibility.

The best SaaS starter kit is not the one with the most features — it is the one whose architectural decisions match your product's actual requirements from day one. Over-buying on features (multi-tenancy you don't need) adds complexity. Under-buying (no multi-tenancy when you need it) forces a rewrite.

For component library decisions that affect all starters, see shadcn/ui vs Chakra UI for SaaS Starters 2026. For the Next.js vs Remix framework decision, see Next.js vs Remix Boilerplate 2026.

Upgrade Paths: What Happens When You Outgrow Your Starter

No starter is permanent. Products evolve, requirements change, and the architectural decisions that were right at month one can become constraints by year two. Understanding the upgrade path is part of the purchase decision.

When Shipfast Runs Out of Road

The most common Shipfast ceiling: adding team accounts. Shipfast is designed for individual users. When a customer says "we want to add a second person to our account," you face a significant refactor:

1. Add an organizations table
2. Add an organizationMembers join table
3. Add org-scoped sessions to NextAuth
4. Update every data query to scope by organization
5. Update the billing model to support org-level subscriptions

This is 2-4 weeks of work on a mature Shipfast codebase. Teams that anticipate this requirement from the start should choose Supastarter or Makerkit instead.

The other common ceiling: payment providers. If you are targeting European customers and want Lemon Squeezy for VAT compliance, you are writing a custom integration from scratch. Stripe is the only payment provider in Shipfast.

When T3 Stack Becomes an Asset

T3 Stack feels slow at first — you spend weeks building infrastructure that commercial starters give you. At month six, T3 becomes an asset. There are no architectural decisions to undo, no customization ceilings, no mandatory SaaS service dependencies. Teams that have built on T3 for a year report fewer unexpected refactors than teams on commercial starters.

The T3 Stack's ceiling is essentially the ceiling of what you can build on Next.js — which is very high.

When Supastarter's Monorepo Pays Off

The Turborepo monorepo architecture feels like overhead for a small team. It pays off when:

• You add a mobile app that shares the same API
• You want to extract a public-facing API separate from the web app
• Your team grows to 4+ engineers working on different features simultaneously
• You want to reuse UI components across multiple apps in the same organization

Teams shipping their first SaaS often find Supastarter's architecture is more than they need. Teams on their third SaaS, who have been burned by monolithic starters that grew unmanageable, appreciate the separation.

Migrating Between Starters

Migrating from one starter to another is rarely worth the effort once you are past the MVP stage. The data model, the authentication flows, and the billing integration are all deeply integrated. "Migrating to Supastarter" at month six means rewriting most of your application.

The practical implication: pick your starter based on where you expect to be in 18 months, not where you are today. Over-engineering is real, but so is the cost of a major rewrite.

---

Starter Kit Red Flags

Things that should give you pause when evaluating a starter:

No CHANGELOG or release notes. If you can't see what changed between versions, you cannot safely upgrade. Shipfast, Supastarter, and Makerkit all maintain changelogs.

Tests that don't pass. Any starter that ships with tests should have those tests pass on a clean clone. Test failures on first install indicate poor maintenance hygiene.

Outdated Next.js version. Starters that are still on Next.js 13 or 14 while Next.js 15 is current have fallen behind on performance improvements and new features.

No database migration strategy. Starters that tell you to "just update the schema" without a migration system create data loss risks in production. Prisma migrations, Drizzle migrations, and Supabase migrations all provide safe schema evolution.

Vague licensing. Some commercial SaaS starters have licensing terms that restrict redistribution or use across multiple products. Read the license before you build a client project on a starter.

Single-author bus risk. A starter maintained by one person with no contributors and infrequent commits is a longevity risk. When the author moves on, you own the maintenance burden.
