What is MonkeysCode?
An agentic IDE that plans, edits, and verifies code across your entire codebase — on any model, on your machine, with every action signed and replayable.
Every model — including yours.
Capuchin (ours), Claude, Gemini, ChatGPT — or run your own via Ollama, llama.cpp, or any OpenAI-compatible endpoint. Switch per task.
Your code stays local.
On-device indexing, air-gapped mode, and local models. Your codebase never has to leave your machine.
Agents prove their work.
Signed, replayable runs. Test-gated commits. Every action is auditable and reproducible.

Meet Capuchin.
A coding model built for shipping software — fast when it's easy, deliberate when it's hard. Plans, writes, and verifies across your whole codebase. The default the moment you open the editor.
Instant when it's easy. Deliberate when it's hard.
Flash mode — answers and edits land immediately for the everyday work — completions, small changes, quick questions.
Reason mode — for the hard stuff, Capuchin thinks step by step — planning multi-file changes, untangling bugs.
Automatic routing — MonkeysCode picks the mode by the task. Speed by default, depth on demand.
Two minds in one model
Built to use tools, not just talk about them.
Reliable tool use — calls your terminal, git, test runner, browser, and MCP servers — accurately.
Plans then executes — produces a plan you approve, then carries it out across files in parallel.
Self-checking — runs your tests and fixes what it broke before handing back.
Agent-native
Reads your codebase, not just the open file.
Massive context window — hundreds of thousands of tokens. Whole services and long histories fit at once.
Repo-aware — paired with MonkeysCode's on-device index, it reasons across files, services, and repos.
Multi-language — strong across TypeScript, Python, Go, Rust, PHP, Java, and more.
