The open coding agent with one simple plan
NinjaCode brings frontier agentic coding to VS Code, JetBrains, Zed and Neovim. Every model — Claude, GPT, DeepSeek, Mistral, Kimi, GLM, Scaleway, Grok — under one monthly subscription. Pick a plan, get credits, code.
GPL-2.0 core · Works with your own API keys too
Why developers switch
Every frontier model
Claude, GPT, DeepSeek, Mistral, Kimi, GLM, Scaleway, Grok and more behind one interface. Switch models per task, or let Auto routing pick the best fit.
A bill you can predict
One flat monthly price, a clear credit allowance, and per-request usage visible in your dashboard. No per-token invoices, no end-of-month surprises.
How it works
From prompt to reviewed diff
1
Describe the change
Chat in your editor. The agent reads your codebase, rules and skills to build real context.
2
The agent works
Plan, edit files, run tests in the terminal — with permission levels you control and checkpoints you can restore.
3
Review and ship
Every diff is reviewable, every action reversible. See exactly how many credits each run used.
The honest math
One plan, every model, no fine print.
Closed agents lock you into one vendor's models or hide "unlimited" plans behind throttles. NinjaCode gives you a clear monthly credit allowance that works across every frontier model — and shows you exactly where it goes.
