Coding tasks, run in a sandbox. Shipped as pull requests.
Nixx is a coding agent that works inside an isolated sandbox — it never touches your machine — and opens a real GitHub pull request you can review and merge.
$ nixx run "implement rate limiting on /api/threads"

How it works
From a plain-language task to a reviewable pull request, without touching your machine.
- 1
Sign in with GitHub
Connect your account so Nixx can clone your repository and open pull requests on your behalf.
- 2
Pick a repository and branch
Choose where the work happens. Nixx provisions an isolated sandbox with a fresh clone.
- 3
Describe the task
Tell the agent what to build in plain language. Its reasoning and execution stay separate, inside the sandbox.
- 4
Review and merge
The agent pushes its work and opens a pull request. Review the diff and merge only what you trust.
Why Nixx
Built for the way you already work, with safety as the default.
Isolated by default
Every command runs inside a sandbox. Your machine and your other work are never touched.
Real pull requests
Work lands as a reviewable pull request, not ephemeral edits. Durable output you can inspect, test, and merge.
GitHub-native
Sign in, pick a repository, and results appear where you already review code. No new workflow to learn.
Start your next task from a sandbox.
Sign in with GitHub and give Nixx something to build.
