Before you write code.
An AI-powered system architecture platform that turns ideas into secure, scalable, production-ready blueprints — so AI builds exactly what your product needs.
Built for long-term products, not fragile demos.
AI can write code.
It can't think in systems.
AI coding tools optimize for speed. Production systems demand security, structure, and foresight. Without architecture, AI-generated apps fail silently — until it's too late.
Insecure authentication & secrets
Plain-text passwords, exposed API keys, and authentication systems built by copy-paste without understanding security fundamentals.
Fragile backend architecture
No separation of concerns, tightly coupled code, and systems that break when you try to scale or add features.
No real path to production
It works on localhost, but deployment? Database migration? Real users? The architecture wasn't built for reality.
Start with a blueprint.
Before code exists, structure must exist. We design how your frontend, backend, database, and infrastructure work together — securely, intentionally, and at scale.

Capabilities
Each feature explains why, not just what.
Visual system architecture graph
See how frontend, backend, and database connect in an interactive, exportable blueprint.
Secure authentication & data flow
Industry-standard security patterns baked into every architecture, not bolted on later.
Database schema & relationships
Properly normalized tables with foreign keys, indexes, and migration strategies.
Backend API structure
RESTful or GraphQL endpoints designed with proper separation of concerns and error handling.
Hosting & infrastructure guidance
Recommendations for deployment, CI/CD, monitoring, and scaling based on your stack.
AI-ready context & rules export
Export .cursorrules files that make AI coding tools follow your architecture precisely.
Your AI finally understands
the whole system.
Export your architecture as strict context. Use it with Cursor, ChatGPT, Copilot, or any coding AI.
Invest in Architecture, Not Debt.
Save hundreds of hours of debugging and thousands of dollars in technical debt. Plan before you build.
Why we charge for Certainty.
AI writes code instantly, but debugging "hallucinated" architecture takes weeks. Plan0 is the governance layer that saves you from that debt. When we launch, our pricing will be a fraction of the cost of a single senior engineer hour.
The Context Bridge
Don't just chat. Export strict .cursorrules that force your AI to follow your architecture.
The AutoSpec Engine
A simulated team of 8 agents validating your security, schema, and API structure.
Production Scaffolding
Download deployment-ready codebases, not just snippets.
Build it right.
From day one.
No credit card required for early access.
Architecture is the real intelligence.
