Sweep

Sweep is an AI junior developer that turns bug reports and feature tickets into real pull requests, handling small refactors and fixes end to end.

Overview

Sweep works like a junior engineer embedded in your repository: you file an issue describing a bug or small feature, and Sweep writes the code, runs tests and opens a pull request for human review. It is designed for well-scoped tasks — fixing an off-by-one, adding a validation rule, refactoring a utility — the long tail of chores that consume developer time.

Sweep understands repository conventions by indexing your codebase, keeps its PRs small and reviewable, and responds to review comments by pushing updates to the same branch. It integrates with GitHub and can run in CI so its output is verified before a human ever looks at it.

Sweep is opinionated about scope: it targets the many small tasks that fill a backlog — fixing bugs, adding tests, renaming usages — rather than attempting large architectural changes. It builds and runs your test suite inside a sandbox before opening a pull request, so reviewers get working code rather than a first draft. The project grew out of the open-source community and continues to publish its approach to building LLM coding agents, making it a useful reference as well as a product.

• Repository indexing for convention-aware code changes
• Responds to PR review comments with updated commits
• Runs tests and linters before opening pull requests
• Best suited to small, well-scoped fixes and refactors
• Open-source core with a hosted service

Pricing

Sweep offers a free open-source version for self-hosting and a hosted service with free trial minutes, scaling to paid plans based on usage.

Who Is It For

Teams with a backlog of small chores and well-maintained test suites who want an AI to clear the easy tickets while engineers focus on hard problems.

FAQ

Is Sweep free to use?

The open-source core is free to self-host; the hosted product charges based on usage after a trial allowance.

Does Sweep offer an API?

Sweep is driven through GitHub issues and pull requests rather than a general API.

How does Sweep compare to alternatives?

Unlike review-only bots, Sweep writes and iterates on code; unlike large autonomous agents, it scopes itself to small, safe changes.

What kinds of tasks does Sweep handle best?

Well-scoped work like bug fixes, small features, test writing and refactors; it deliberately avoids large changes that are hard for humans to review safely.
