Logic Before CodeNo Illusions

Logic64 is the AI platform for production-grade system architecture.
Start your project with validated stack decisions, service blueprints, API contracts, data models, infrastructure design, and zero hallucinations.

Logic64 Studio Interface

Your dev environment, ready in seconds.

A live look at the Studio mid-flight. Logic64 designs the architecture, locks the decisions, and writes the constitution before you touch a file.

DiagramList

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

The industry is moving beyond prompt engineering.

Production AI systems require more than prompts: reliability, orchestration, validation, memory, and architecture consistency are becoming core engineering concerns. Logic64 was built around this shift.

Logic64 turns these engineering principles into a governed AI workflow.

Your stack, decided.
Not assembled.

Describe what you're building. Logic64 reads scale, constraints, and surface — then commits to the exact technologies that fit.

Step 01 · Plan — the AI interviews you, adapts to your stack, and locks every architectural decision before a single file is written.

Step 03 · Export — run logic64 pull and your full workspace arrives: agents, rules, config, and CLI toolchain — all wired and ready.

Step 02 · Build — locked decisions stream into files in real-time over SSE, each one validated the moment it's written.

Guarantee — every file passes an 11-step validation chain. One broken rule and the entire bundle is hard-rejected, never delivered.

Production-grade workspaces. No configuration required.

Every stack. Every scale. Zero configuration.

Schema locked. Auth defined. Billing scoped — before line one. Your AI never crosses layers.
