The high cost of
building from scratch
Engineering shouldn't be about reinventing the wheel. Most startups die in the auth and billing phase.
Time Waste
Spend hours setting up boilerplate, repo structures, and CI/CD pipelines before writing a single feature.
- ✕Configure ESLint, Prettier, Husky
- ✕Wire up CI/CD from scratch
- ✕Design and migrate the DB schema
- ✕Set up email provider & templates
- ✕Build auth flows before your first user
6+ weeks
lost before first feature ships
Auth Headaches
Complex multi-tenant RBAC, OAuth providers, and session management that usually takes weeks to perfect.
- ✕Google, GitHub, and magic-link OAuth
- ✕Session expiry & refresh token logic
- ✕Role-based access per organisation
- ✕Invite flows for non-existing users
- ✕Email verification & account recovery
40+ hours
typical auth implementation
Billing Complexity
Webhooks, subscription logic, tiered pricing, it's harder than it looks.
- ✕Webhook signature verification
- ✕Failed payment & dunning logic
- ✕Proration on mid-cycle plan changes
- ✕Customer portal & invoice history
- ✕Tax calculation across regions
3–5 sprints
to get billing production-ready

Frequently asked questions
What's included in the open-source version?
The community version includes the full Next.js 16 app, Better Auth with OAuth and magic links, a Prisma schema wired to Supabase, and the base project structure — everything you need to get started without spending a dime.
Do I need to know AI to use the Pro AI features?
No. The AI agent logic, tool calling, and streaming responses are pre-built using the OpenAI Agents SDK. You just configure your API key and start extending — no ML background required.
How does billing work? Can I switch plans later?
Billing is handled end-to-end via Lemon Squeezy — subscriptions, webhooks, and the customer portal are all wired up. You can upgrade, downgrade, or cancel at any time directly from the portal.
Is this production-ready or just a boilerplate?
It's production-ready. The stack includes CI/CD via GitHub Actions, one-click Vercel deployment, Redis caching with Upstash, vector search with Qdrant, and RBAC for multi-tenant apps — not a toy starter.
What database does it use and is it easy to migrate?
It uses Postgres (via Supabase) with Prisma ORM for type-safe, migration-backed queries. Switching providers is straightforward — update the connection string and re-run migrations.
What do I get with the Pro plan beyond the code?
Pro includes access to the private Discord community where you can ask questions, get architecture feedback, and stay updated on new features and releases as the kit evolves.
