A Bolt.new alternative for work a browser tab cannot hold: Fixa runs on its own Linux machine in the cloud, works on your repository and opens pull requests.
New session
Work on my existing repository
Better fitFixa
Fixa clones your repository onto its own machine, works on a branch and ends with a pull request you review.
Fixa's plan
Bolt shows a JavaScript idea running fastest. Fixa is for work that needs a whole computer.
Bolt.new runs a Node environment inside your browser with StackBlitz's WebContainers. The preview is instant and there is nothing to set up.
Fixa runs on a Linux machine in the cloud. It can install system packages, run Python, Go or Rust, drive headless Chrome, run long test suites and open pull requests on your repository.
Try the chooser below with the job you have. When Bolt is the quicker answer, it tells you.
Each session gets its own computer with a terminal and your whole repository. It installs, builds, tests and starts the dev server.
$ git clone github.com/acme/billing$ pnpm installPackages: +412 done in 6.2s$ pnpm testTests 41 passed (41)$ pnpm devready http://localhost:3000
Connect GitHub and pick a repository and branch, or paste the URL of a public one. No new project to migrate into.

The work happens on a branch named after the task. Review the diff and merge it, or comment and Fixa carries on.
Fix login redirect loop
Middleware sent signed-in users on /login back to /login. Closes #12.
Mention @Fixa in a thread. It answers there with Stop and Open buttons and posts the pull request when it is done.

If the job is bigger than a JavaScript prototype, yes. Fixa runs on a real Linux machine, works in any language and opens pull requests on your repository. For a quick in-browser prototype, Bolt is faster to start.
Where the code runs. Bolt runs it inside your browser tab with WebContainers. Fixa runs it on its own cloud machine, so it can install anything, run any language and keep working after you close the tab.
Yes. The work happens on Fixa's machine, not in your browser. Close the tab, come back later and the session, its preview and its pull request are there.
That is what it is built for. Connect GitHub, pick a repository and branch (or paste the URL of a public one), and Fixa clones it onto its own machine.
You choose per task: GPT-6 Luna, GPT-6 Sol, GPT-6 Astra, Claude Haiku 5.5, Claude Sonnet 5.5, Claude Opus 5.5, Claude Fable 5.1 or Grok 4.7.
It is free to start. Starter is $8 a month with a 7-day free trial, Pro $20, Max $40 and Ultra $80, each with more usage. Change or cancel any time.
