Klenny CodeYour desktop coding agent.
Any model. Zero leash.
Klenny Code is a free, open-source AI coding agent for Windows, macOS, and Linux. Bring your own OpenRouter key and unleash hundreds of frontier models — Claude, GPT, Gemini, and more — on your real codebase, with memory, cross-project lookup, and a scheduler that works even while you're away. No subscriptions. No lock-in. Just a very good boy with a very big toolbox.

Everything a coding agent should be. And then some.
Klenny fetches, refactors, remembers, and even runs errands for you — all from one free, open-source app.
Bring your own key, use any model
Connect your own OpenRouter API key and pick from hundreds of models — Claude, GPT, Gemini, and more — all through one account. No vendor lock-in, no marked-up tokens, just the model you want at the price you choose.
Memory that actually sticks
Project and global memory files plus auto-generated notes mean Klenny remembers your conventions, decisions, and quirks across sessions — so you stop repeating yourself.
Cross-project lookup
Ask Klenny to reference, search, or port a feature from one of your other projects without ever leaving your current window. Your whole portfolio, one context away.
Scheduling & personal assistant
Set up recurring background tasks, connect Gmail and Discord, and let Klenny handle chores unattended from the system tray — even when the app is minimized.
Plan mode & approvals
Ask Klenny to plan first. Review every proposed change as a diff before it touches a single file — full control, zero surprises.
Skills & subagents
Reusable, Cursor-style skills and parallel subagents tackle research and multi-step work in the background, so the main thread stays fast and focused.
Semantic codebase search
An optional vector index finds code by what it means, not just what it says — perfect for sprawling codebases where grep alone won't cut it.
Real terminal, real cost control
A genuine interactive shell lives right in the app, alongside a spending cap and cost report so you always know exactly what you're spending, on what.
Free & open source, always
MIT licensed, fully open on GitHub, no subscriptions or hidden fees. You only ever pay OpenRouter directly for model usage — at whatever rate you choose.
