Your Terminal.
Now Autonomous.
Crayon is an ultra-capable AI coding agent that lives directly in your terminal. It understands your entire codebase, plans, executes, and iterates. Chill out while it writes the code.
Trusted by elite developer teams
Autonomous from end to end
Crayon isn't an autocomplete. It's an agentic loop that understands, plans, and executes your tasks perfectly.
Context Engine
Instead of drowning the context window, Crayon intelligently searches your codebase and loads only the specific files, imports, and dependencies needed.
Diff-Based Execution
Crayon creates a step-by-step execution plan and writes surgical diff patches to safely modify files without destructive overwrites.
Self-Healing Loop
It runs tests and builds automatically. If it detects a failure, it reads the error, generates a fix, and re-tests until successful.
Stop sending your whole repo to the LLM.
Our Context Engine acts like a senior engineer reading your codebase. It traverses ASTs and dependency graphs to fetch exactly what's needed, reducing token usage by 95% while improving output accuracy.
It writes the code, and fixes its own bugs.
Crayon operates in a secure Docker sandbox. It executes test suites after applying diff patches. If a test fails, the Self-Healing Loop analyzes the stdout stack trace and patches the issue autonomously.
Loved by engineers
Don't just take our word for it.
"It literally built a Next.js dashboard from my Figma export in 3 minutes."
Sarah L.
Frontend Lead
"The diff patches are surgical. It never overwrites my custom logic."
James T.
Senior Engineer
"I let Crayon run my refactoring tasks overnight. I wake up to perfectly typed PRs."
Elena M.
CTO
"Context Engine is the real deal. It only grabbed the 4 files needed to fix the auth bug."
David K.
Fullstack Dev
"Best AI coding tool I've used. It's actually autonomous."

Frequently Asked Questions
Copilot is an autocomplete tool. Crayon is an autonomous engineer. You don't write code with Crayon; you give it a PRD or a task, and it plans, executes, tests, and self-heals the entire implementation without your intervention.
Other tools send your entire repository to the LLM, which is expensive and often causes hallucinations. Crayon traverses your codebase's AST to surgically fetch only the specific files, functions, and imports necessary for the task, achieving a 95% token reduction.
Yes. Crayon operates using diff-based execution. It never blindly overwrites files. It generates surgical diff patches that you can review. Additionally, we strongly recommend running Crayon within a Docker sandbox for complete security.
Absolutely. Crayon is designed to index and navigate repositories with 100k+ LOC. Its intelligent RAG and AST traversal means it understands complex architecture just as well as small projects.
