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
anytypes 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:
- No commits in 6+ months — Not maintained
- Webhook without signature verification — Security hole
- No documentation — Setup will be painful
- No refund policy on paid product — Red flag
- Real credentials in repository — Bad security practices
- Only handles
checkout.session.completed— Incomplete billing - 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.
The Hidden Costs Most Buyers Miss
The purchase price is the smallest cost when evaluating a SaaS boilerplate. The costs that actually matter are invisible until after you've committed.
Ramp-up time is the largest variable cost. A well-documented boilerplate like Nextbase or Makerkit takes a developer one to two days to understand well enough to productively extend. A poorly documented boilerplate can take a week of reading code before you're confident making changes. At even $50/hour in developer time, the documentation quality difference is worth far more than a $200 price difference between products.
Mandatory dependencies add ongoing costs that the purchase page doesn't advertise. Some boilerplates assume Clerk ($25+/month) rather than including an auth configuration you can swap. Others require Supabase Pro ($25/month) for features the boilerplate depends on. Add up the required monthly costs before deciding "this is cheaper than that one."
Breaking changes in the underlying stack cascade into your boilerplate. When Next.js released the App Router, teams on Pages Router-based boilerplates faced a choice: stay on the old pattern or invest weeks migrating. Teams on actively maintained boilerplates got the migration handled by the boilerplate author. Teams on abandoned boilerplates made the migration themselves or stayed on outdated patterns. Active maintenance isn't a nice-to-have — it's a cost hedge against major framework upgrades.
Evaluating Code Before You Buy
Most paid boilerplates offer either a demo or a preview of the code. Use both before purchasing:
Check the auth flow end-to-end in the demo. Sign up, verify email, log in, reset password, log out. Any friction in these flows is amplified when your real users encounter them.
Look at the Stripe webhook handler if you can. This is where most boilerplates cut corners. A production-quality webhook handler covers checkout.session.completed, customer.subscription.updated, customer.subscription.deleted, and invoice.payment_failed at minimum. A handler that only covers checkout completion will leave your database in a stale state when users cancel or upgrade.
Read the environment variables documentation. The quality of the .env.example file and the documentation explaining each variable is a reliable signal for the overall documentation quality. If the author explains why each variable exists and what format it expects, they're thorough. If it's a list of variable names with no explanations, expect similar sparseness throughout the docs.
Post-Purchase Red Flags
Three signals indicate a boilerplate that will become a liability rather than an asset:
When something breaks and you search the community Discord or forum, and the response is "just delete those files and build it yourself" — that boilerplate is too thin to be worth the price. You've paid for a starting point, not a starting point with known gaps.
When you check the GitHub commits and the last meaningful update was 8+ months ago despite Next.js, React, or other core dependencies having received major updates since then — the author has moved on. You're inheriting technical debt that no one is paying down.
When you contact support before purchasing with a specific technical question and receive a non-answer or no response within 48 hours — that's the quality of support after you've paid. Pre-sales support is always better than post-sales; if it's bad before the purchase, it will be worse after.
