Opencode

Opencode is an open-source AI coding agent designed to help developers read, write, refactor, and understand code across entire repositories. It connects to your codebase, analyzes project structure, and assists with tasks ranging from small edits to multi-file feature implementations. The primary purpose of Opencode is to provide an auditable, extensible AI assistant that developers can run and customize within their own infrastructure or workflows.

Key features include repository-aware context handling, enabling the agent to navigate files, follow imports, and maintain consistency across large codebases. Opencode supports code generation, refactoring, documentation updates, and test creation, with the ability to propose and apply changes as structured diffs or pull requests. Because it is open source, teams can inspect the logic, extend capabilities with custom tools or plugins, and integrate it into existing CI/CD pipelines or editor workflows. The tool is designed to work with multiple programming languages and frameworks, making it suitable for polyglot environments.
