Sweep
About
Sweep began in 2023 as a GitHub app that behaved like a junior developer: assign it an issue and it planned changes, edited files across the repository, and opened a draft pull request for review. That workflow ran on GPT-4 with a repo-map and sandboxed validation loop, and the project drew roughly 7.7k stars as one of the first open-source autonomous-PR agents. The team subsequently pivoted to building an AI coding assistant distributed as a JetBrains Marketplace plugin, leaving the original GitHub-app codebase without active development while sweep.dev now points at the plugin. The repository remains available under a dual license — MIT for the free components with an Enterprise Edition license covering commercial parts — and is still referenced as a reference implementation of issue-to-PR automation. JetBrains users wanting an agent inside IntelliJ-based IDEs are its current audience.
