Describe the change.
Kitsune writes it.
Kitsune reads your repository, plans the edit, runs the tools, and shows you the diff before anything touches your branch. A small, local-first agent for real codebases.

How it works
Three moves. No prompt gymnastics.
Kitsune works like a careful teammate: it looks first, proposes second, and only changes code after you have seen what it wants to do.
02
Describe the outcome
Say what you want in plain language. It returns a plan before it edits anything.
03
Review and ship
Approve the diff, keep the checkpoint, or roll it back. Then commit — your branch, your call.
Product
An agent built like a developer tool.
Fast, inspectable, and boring in the right places. Kitsune is designed for people who read the diff before they merge.
Repo-aware, not chat-aware
Glob, grep, read, and a project map. Kitsune finds the files that matter instead of guessing from a filename.
Plan before patch
Every run starts with a short plan you can steer. Reject it, edit it, or let it go — before a single line changes.
Diffs, not surprises
Writes are previewed line by line. Checkpoints let you undo a whole run without rewriting Git history.
Tools on a leash
Shell, Git, web, and MCP tools. Reads run freely; writes and risky commands ask first, every time.
Detached runs
Close the tab. The run keeps going server-side and replays when you come back — no lost work, no babysitting.
Tiny by design
One Go binary, no Electron, no 500 MB runtime. It starts in milliseconds and stays out of the way.

Under the hood
One run, start to finish.
No hidden state, no mystery edits. Every stage is visible, interruptible, and reversible — the way a good pair session should feel.

FAQ
The short answers.
Still deciding? The docs cover the client, the tools, and the MCP setup in detail.
Open the docsWhat exactly is Kitsune?
An agentic coding client. One small binary that reads your repository, plans a change, runs your tools, and hands you a diff you can read before anything is committed.
Do I need a credit card to start?
No. The Free plan needs no card and still gives you a real token budget every five hours and every month.
What counts as a token?
Everything the model reads and writes: your file context, tool output, its own reasoning, and the final answer. Reasoning tokens are counted too — the meter never hides them.
Which models can I use?
Kitsune runs on XUSS-hosted models. Free covers the fast tier; paid plans open the full chat model range, and you choose the model and thinking level per run.
Will it run dangerous commands on my machine?
Reads happen on their own. Writes, shell commands, and network fetches ask for approval first, and every run leaves a checkpoint you can undo in one click.
Does it fit my stack?
Any repo with a toolchain. Kitsune drives whatever your project already uses — npm, pnpm, pytest, cargo, composer, go test — and reads the language it finds.
What happens when I hit a limit?
The run stops cleanly, the diff stays on your disk, and your budget returns on the next window. Nothing is lost and nothing is billed twice.
