A Devin alternative for GitHub repositories: hand Fixa an issue, it works on its own cloud machine and opens a pull request. Free on public repos with 50+ stars.
New session
Fix an issue in my open-source repo
Better fitFixa
On a public repository with 50+ stars Fixa runs free: GPT-6.1 Sol if you maintain it, GPT-6.1 Terra if you contribute. No form and no card.
Fixa's plan
Devin and Fixa do the same kind of work: an AI engineer with its own machine takes a task and comes back with a pull request.
Devin, by Cognition, is the bigger platform. It has a desktop editor with tab completions, works with GitHub, GitLab and Bitbucket, takes tasks from Slack, Linear and Jira, and sells team plans with SSO and admin controls.
Fixa is smaller and cheaper. It works on GitHub repositories, takes tasks from issues, Slack, Linear, Sentry and schedules, and runs free on public repositories with 50+ stars. Paid plans start at $8 a month.
Use the chooser below with the job you have. Where Devin fits better, it says so.
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.

If your code is on GitHub and you want to hand off issues for less, yes. Fixa clones your repository onto its own machine, fixes the issue, runs your tests and opens a pull request. If you need GitLab, Jira, an editor or enterprise controls, Devin covers more.
Yes. On a public GitHub repository with 50+ stars, maintainers get GPT-6.1 Sol free and contributors get GPT-6.1 Terra free, up to a daily and monthly budget per person. Every pull request it opens ends with one line saying Fixa opened it.
Not yet. Fixa works with GitHub repositories and takes tasks from GitHub issues, Slack, Linear, Sentry, schedules and the app.
Yes. Open any issue on GitHub and change github.com to fixa.dev in the address bar. On a repository you don't maintain, the change goes to your fork and you open the pull request yourself.
