From a fresh install to your first shipped change. Connect a repository, launch a workspace, read the changeset, and ship.
Six steps, a few minutes end to end. Each one is something you do in the app.
Cohalen is a desktop app for Windows, macOS, and Linux, currently in early access. Join the waitlist and we'll send you a build. Download it, open it, and sign in.
A GitHub connection lets Cohalen push, open pull requests, and merge as your account, so your commits are authored by you. Authorize it once.
You only need it before you push. Skip it now and the app asks you inline at your first push.
A repository is the git source your workspaces branch from. Connect one: Open a folder that's already a git repository, or Clone from a remote. Your clone stays on your machine.
A workspace is one unit of parallel work, an isolated git worktree with one agent working in it. Launch one, pick the agent, and give it a task. For example:
Add a rate limiter to the /api/waitlist route:
- 5 requests per minute per IP
- return 429 with a Retry-After header
- cover it with a testThe agent works in the background. Launch more workspaces to run several agents at once. Each has its own worktree, so they never step on each other's files.
Every workspace has a spend cap, on by default. When it hits the cap the agent stops, so a runaway loop can't become a runaway bill.
When the agent finishes, open Review. It shows the changeset: everything the task changed, as one whole.
Leave a note on a diff line for the agent to fix, or edit the file yourself.
Checks gathers everything that decides whether the workspace can merge and boils it down to one verdict. A blocked workspace reads as blocked, with a count of what's left. The verdict gives you one action at a time:
Cohalen merges through your GitHub connection, so branch protection still applies.
What Cohalen is
A local-first desktop app that runs many AI coding agents in parallel, each in its own git worktree, and gives you one place to review and ship what they wrote.
