Pre-built architecture and enforced AI rules that keep Cursor from breaking your project — so you can ship features without architectural drift.
Built with modern stack
Documented building system to ship faster with AI
Coming soon...
AI is great at isolated components, but it breaks down on product architecture surprisingly fast. This starter gives you the developer-written SaaS core, so Cursor can build features without reinventing the foundation every session.

AI can generate screens quickly, but it often makes a mess of project structure. Here the routing, folder boundaries, and clean baseline are already thought through by a developer.

AI can write queries, but it regularly gets schema decisions, permissions, and auth/data relationships wrong. Here the data layer starts closer to a real SaaS baseline.

Checkout flows, billing states, and webhooks are exactly where AI tends to fall apart. Here that logic is already wired by hand, without the usual pain in the last 20%.

Data isolation, tenant boundaries, and ownership logic are some of the hardest things for AI to reason about. Here the foundation is already shaped to survive scaling.

A complete Starter Kit with embedded architecture rules that guide AI development.
Every file has its place. Clear separation between pages, components, utilities, and configuration.
Pre-configured rules that tell Cursor exactly how to work within your project boundaries.
What this covers
Keeps AI focused on your current task, not random rewrites
Protects project structure so files stay organized
Prevents risky changes that can break working features
Helps AI keep context between sessions
Reduces time spent fixing generated code
This comparison shows the shift from fragile vibe-coded growth to a more structured way of building with AI, where speed does not come at the cost of architecture.
Cursor and AI feel magical at first, until your project starts falling apart.
Setting up the base and architecture via AI eats a lot of resources and tokens. In the end the foundation often turns out wrong anyway — and that means more time and money spent on rework.
AI forgets why decisions were made. Without a shared source of truth, every new feature risks breaking existing logic.
What started as a fast prototype turns into something no developer wants to maintain, extend, or refactor.
Instead of shipping features, you fight regressions, duplicated logic, and broken flows introduced by the AI.

Start with a solid architecture that AI can accelerate instead of slowly breaking.

You get a built Next.js + Supabase base with auth and multi-tenancy. No spending tokens and months on setup — you save time and money.

PRD and project structure are shaped for AI: the model keeps product logic in mind and doesn't rewrite everything from scratch each time.
What started as a fast prototype turns into something no developer wants to maintain, extend, or refactor.
Built-in rules and invariants define where things live and how to add features. The project can scale and be handed off without chaos.
Instead of shipping features, you fight regressions, duplicated logic, and broken flows introduced by the AI.
AI works within clear boundaries: fewer regressions and random edits, more time on actual development instead of cleanup.
Other starters give you files. We give you a system with clear rules so AI accelerates you instead of rewriting you.
You get a real SaaS foundation in hours, with rules so AI doesn't turn your codebase into a one-off prototype.
Finally, AI that doesn't rewrite my app every session. The rules keep Cursor in line and the codebase predictable.
