What to Look for in a SaaS Boilerplate

TL;DR

Most developers buy boilerplates without a systematic evaluation. This checklist covers 50+ criteria across 6 categories: technical quality, features, documentation, community, business, and fit. Score each boilerplate before buying to avoid the most common mistake: realizing 2 weeks in that the boilerplate doesn't match your needs.

---

Category 1: Technical Quality (Most Important)

Code Quality

• TypeScript throughout (not just types for auth/billing)
• Environment variables validated on startup (t3-env, Zod)
• No any types in critical paths (auth, billing, data access)
• Consistent error handling (not mix of throw + return null)
• ESLint + TypeScript strict mode enabled
• Imports organized, no circular dependencies

Security

• Stripe webhook signature verified before processing
• Sessions use httpOnly, secure, sameSite cookies
• No SQL injection vectors (ORM used throughout)
• CSRF protection in place
• Sensitive data not logged
• Auth state validated server-side (not just client-side)

Performance

• Images optimized (Next.js Image component or equivalent)
• No N+1 queries in auth or billing flows
• Database indexed on frequently queried fields
• Bundle size reasonable (check Vercel build output)

Testing

• Any tests at all (many boilerplates have zero)
• Auth flows tested
• Billing flows tested
• CI runs tests on PRs

Category 2: Features

Authentication

• Email + password
• OAuth providers (Google minimum)
• Magic link / passwordless
• Email verification
• Password reset
• 2FA/TOTP (if needed for your market)

Billing

• Stripe checkout
• Subscription management
• Customer portal (update card, cancel)
• Webhook handler (all relevant events)
• Plan tiers (free, pro, etc.)
• Trial period support
• Annual billing option
• Per-seat billing (if B2B)

Multi-tenancy (if needed)

• Organization/team creation
• Member invitations
• Role-based permissions (member/admin/owner)
• Per-organization billing

Communication

• Transactional email (welcome, password reset)
• Email templates (HTML, not plain text)
• Notification system

Content

• Blog/MDX (if needed)
• SEO meta tags
• Sitemap generation
• OG images

Admin

• Admin panel (user management, subscription management)
• Basic analytics/metrics

---

Category 3: Documentation

Getting Started

• Clear prerequisites listed
• Setup guide covers local development
• All environment variables documented
• Common errors + solutions

Architecture

• Project structure explained
• How to add a new feature (cookbook)
• How the auth flow works
• How billing is structured

Deployment

• At least one deployment platform covered
• Database migration guide
• Environment variable management in production

---

Category 4: Maintenance and Updates

• Last commit within 2 months
• Active PRs and issues
• Changelog or release notes
• Dependencies not critically outdated (< 6 months)
• Responds to security issues quickly
• Version history shows consistent updates

---

Category 5: Community and Support

• Discord or forum exists
• Response time in community < 24 hours
• Creator active in community
• Tutorial content (blog, YouTube, examples)
• Stack Overflow presence (for common questions)
• GitHub stars (relative signal)

---

Category 6: Business Fit

Price

• Purchase price matches budget
• License type acceptable (lifetime vs annual vs MIT)
• Refund policy (30-day is industry standard)
• No hidden costs (some boilerplates require paid services)

License

• Can use in commercial products
• Can deploy to client projects (if agency)
• Open source vs proprietary code
• Can customize without attribution

Stack Match

• Framework matches your preference (Next.js, Remix, SvelteKit, etc.)
• Database matches (PostgreSQL, SQLite, MongoDB)
• ORM matches (Prisma, Drizzle, TypeORM)
• Auth provider matches (NextAuth, Clerk, Supabase)
• UI library matches (shadcn, Tailwind, Radix)
• Deployment target matches (Vercel, Railway, Fly.io, custom)

Scoring Your Evaluation

Use this scoring template:

Category	Weight	Your Score (1-10)	Weighted
Technical Quality	30%
Features	25%
Documentation	20%
Maintenance	10%
Community	10%
Business Fit	5%
Total	100%

Interpretation:

• 8.0+: Buy with confidence
• 6.5-7.9: Acceptable, with known trade-offs
• 5.0-6.4: Consider alternatives
• Below 5.0: Avoid

Quick Disqualifiers (Instant No)

Any of these is an automatic elimination:

1. No commits in 6+ months — Not maintained
2. Webhook without signature verification — Security hole
3. No documentation — Setup will be painful
4. No refund policy on paid product — Red flag
5. Real credentials in repository — Bad security practices
6. Only handles checkout.session.completed — Incomplete billing
7. Licensing that prevents commercial use — Deal breaker for SaaS

---

The Final Question

After scoring, ask: "Does the creator build products with this boilerplate?"

Marc Lou (ShipFast) has launched 10+ products with ShipFast. Kent C. Dodds built epicweb.dev on Epic Stack. Creators who dog-food their own tools make better tools.

A boilerplate built by someone who's never shipped a product with it will have different blind spots than one built by a serial founder.
