An open-source coding agent that can understand a repository, edit files, run terminal commands, and verify changes with human approval.
Best for: Developers who want an agentic workflow inside VS Code, JetBrains, the terminal, or an application built with the SDK.
What you can do with it
- Explain an unfamiliar repository and map the files involved in a change
- Implement a feature across multiple files and run its tests
- Investigate a bug with repository context, terminal output, diffs, and checkpoints
Good to know
- Can understand and modify a real repository across multiple files
- Supports terminal, tests, diffs, checkpoints, MCP, and human approval
- Open-source and works with many model providers instead of one locked model
Limitations
- AI inference is still billed by the selected provider or usage plan
- Commands and edits can affect a real project and need review
- Large repositories can consume substantial context and tokens
