Codewhale

An open-source coding agent for macOS, Linux and Windows that uses local or hosted models, with terminal and local browser clients that need no account.

Alternative to:

Codewhale is a coding assistant for developers who want an agent to inspect projects, make changes and check the results. It runs on your computer and lets you choose the model and the permissions it works under.

Code changes and checks: Ask the agent to read a repository, edit files, run commands and execute tests, then review its edits as diffs and inspect command results.
Permissions and recovery: Explore a project in planning mode without making changes, set approval requirements, interrupt work and recover workspace changes with undo and restore tools.
Saved work: Resume sessions with their conversations and tool results, or turn recurring tasks into scripts and saved workflows for use in automation or CI.
Agent teams: Split larger tasks among agents with different models and roles through Fleet, and follow their progress.
Tool extensions: Connect MCP servers and plugins, or adapt project behavior through Skills and hooks, including support for existing Claude Code plugins.

Codewhale is open source under MIT. Its terminal and local browser clients run on macOS, Linux and Windows without a Codewhale account and share the same local session.

Local model backends include Ollama, vLLM and SGLang. Hosted connections support your own API key or supported provider sign-in, with inference handled by the external provider. Usage counts are on by default, and you can disable that telemetry.
