Your architecture.
Validated, not guessed.

Describe your project.
Logic64 generates a production-grade system architecture, hallucination-constrained and engineer-ready.

Logic64 Studio Interface

Your dev environment, ready in seconds.

Watch Logic64 set up a full workspace in real-time — just describe your project.

Describe your project…

Stop guessing. Start governing.

Every team building with AI agents faces the same invisible problem — and most never name it until it's already broken.

The Problem

You're the architect.
And the scaffolding crew.

Every AI-assisted project starts with the same hidden tax: hours building the environment that should enable you, not consume you.

✕Manually crafting CLAUDE.md from scratch
✕Assembling agent specs with no template
✕No governance → AI drifts off-spec
✕Breaks when a new team member joins
✕Rebuilt from zero on every project
The Paradigm

Logic64 is the architect.
You just describe the project.

A specialized agent with deep understanding of your project generates your entire constitution — validated, locked, and ready to ship.

✓CLAUDE.md, agents/, mcp.json — all auto-generated
✓Every rule derived from your actual architecture
✓Constitutional governance — AI never drifts
✓Ships inside the project — scales with the team
✓One command, every project, every time

Please build a SaaS with Next.js, use Tailwind, don't forget auth with Clerk, DB is Neon, don't mix App router with Pages router, backend should use Fastify not Express, add BullMQ for queues, Redis for caching, keep the Python engine separate with FastAPI...
