Codewhale

Codewhale is an open-source coding agent that reads files, edits code, runs commands, and executes tests in the terminal.

Codewhale is an open-source coding agent built for the terminal and local browser. It reads project files, edits code, runs shell commands, and checks its work by running tests. Users choose their AI models, including local options like Ollama or hosted providers via API keys, and set specific permissions before tasks begin. The platform supports plugins, MCP, computer use previews, saved sessions, and a fleet feature to assign tasks to multiple agents with different roles. It runs on Linux, macOS, and Windows, with preview support for Android on Termux.
