Modern stack, not yesterday's
Next.js 16, React 19, Tailwind v4 with oklch tokens, TypeScript 5.9 strict on Starter / AI / Core. If a template is still on Pages Router and Tailwind v3 in 2026, you are paying interest on technical debt from day one.
Why Boilerlykit
Modern stack. Honest pricing. Real docs.
Six reasons engineers choose Boilerlykit over the 10 other Next.js SaaS boilerplates they bookmarked. And two reasons you might pick someone else - because we would rather lose a sale than oversell the fit.
Six principles we do not bend on
These are decisions, not aspirations. Change any one of them and it stops being Boilerlykit.
One-time purchase, perpetual license
Pay once, own the repo, keep the updates we publish for your tier. No recurring subscription on the template code itself. You can pause, fork, or walk away at any point.
Private GitHub repo, full source
Delivery is a GitHub collaborator invite to a private repository. Components, API routes, SQL migrations, MDX docs - readable, commented, diffable. No obfuscated bundles or DRM.
Docs first, marketing second
Every template ships with MDX documentation that answers install, rebrand, deploy, and the pre-purchase questions. Buyers can evaluate fit before checkout, not after.
Polar MoR checkout
Polar is the Merchant of Record - EU VAT, invoices, and refunds handled under their buyer terms. For EU/UK buyers this is the difference between a proper receipt and a compliance scramble.
Scoped tiers, not one-size-fits-all
Four templates, not one. Pay $59 for a content shell, $199-$259 for a full SaaS. Never pay enterprise prices for a one-pager or indie prices for a multi-tenant product with audit logs.
Boilerlykit vs. the typical Next.js boilerplate
Nine axes buyers actually compare on. We marked the ones where Boilerlykit is ahead - and the ones where we are not.
| Axis | Boilerlykit | Typical boilerplate |
|---|---|---|
| Stack | Next.js 16 + React 19 + Tailwind v4 (Starter, AI, Core) | Mixed - many still on 14/15, Tailwind v3 |
| Billing | Stripe subscriptions + credits + webhooks + customer portal | Stripe checkout wired; webhook + edge case coverage varies |
| Multi-tenant | Workspaces + RLS + 4-role RBAC + SAML SSO hooks + audit logs (Core) | Single-tenant demos; team_id column on some |
| AI | Streaming chat, RAG on pgvector, token-based credits (AI) | fetch() to OpenAI, rarely full RAG |
| i18n | EN / FR / ES via next-intl on Agency template; EN on others today | EN-only on most |
| License | One-time, perpetual, private repo access | Usually one-time, occasionally subscription or seat-locked |
| Checkout | Polar MoR - EU VAT + invoices + refunds handled | Mixed: Lemon Squeezy, Paddle, raw Stripe, or Gumroad |
| Price floor | $59 Starter, $199 Core, $229 Agency, $259 AI (launch) | $99-$299 one-time, higher for team tiers |
| Community size | Small - we just launched | ShipFast has the strongest community in the category |
"Typical boilerplate" is a composite of what we see across ShipFast, Makerkit, Supastarter, and Bedrock as of April 2026. Read our honest comparison post for a vendor-by-vendor breakdown.
The toolkit
Works with your stack
Tweak models, retrieval, or pricing in config instead of rewriting the app. AI, Core, and Agency all sit on Next.js 16 and TypeScript each repo just emphasizes a different slice of the same modern toolkit.
01Models
Multi-model
SaaSForge AI ships with OpenAI and Anthropic. Map usage tiers to your catalog prices and env-driven limits instead of scattering magic numbers through the UI.
02Retrieval
RAG + pgvector
Chunk uploads, store embeddings, and search in Postgres. Core leans on the same database discipline for tenant data.
03Billing
Credits + subscriptions
AI handles credits and renewals through webhooks; Core handles subscriptions and the customer portal. Retries stay safe.
04Auth
Sessions with RLS
Core and AI use Supabase with SSR-friendly sessions and row-level security, so workspace rows never leak across accounts.
05Deploy
Railway or Vercel
Ships cleanly to Railway or Vercel with sane env notes. The AI template includes cron-friendly routes for things like credit resets.
06Fallback
Provider redundancy
Offer a premium model and keep a fallback path ready when an API is slow or returns errors, so users never see a hard outage.
07CMS
Directus + editorial SEO
Agency uses Directus 11 so editors change services and case studies in the CMS while the Next app stays deployable.
08Foundation
App Router + typed UI
TypeScript, Tailwind, and shadcn/Radix across the catalog. Fork, retheme, and keep every component predictable.

Who Boilerlykit is NOT for
We would rather lose your $259 than take it and watch you refund a week later. Skip us if any of these fit you:
- You want the biggest possible community and the most YouTube tutorials. ShipFast still wins on sheer volume - buy it instead.
- You want an enterprise monorepo with a decade of battle-testing on large teams. Makerkit's higher tiers are closer to that than we are.
- You want a template that ships EN-only product features and also supports RTL locales out of the box. We do not ship RTL today.
- You are building something the SaaSForge tiers do not fit - e.g. a marketplace, a CLI tool, a React Native app. Don't force fit. Pick something built for it.
Decision time
Compare the four templates. Pick the one that fits.
Starter for a polished shell. AI for RAG and chat. Core for multi-tenant B2B. Agency for multilingual marketing sites. Never pay for what you do not need.
