Codewhale

Codewhale is an open-source agent that reads your project, edits files, runs commands, and checks its work using a hosted or local model you choose. Start with one task in your terminal. For a larger job, give parts of the work to agents with different models and roles.

Terminal preview from a v0.9.12 development build.

Install

macOS / Linux — install the official GitHub release:

curl -fsSL https://codewhale.net/install.sh | sh
"$HOME/.local/bin/codewhale"

The installer selects the latest published release. The changelog also describes the next release's unreleased candidate; those changes are not included in published downloads until the release is available.

Windows: download the matching installer or archive from GitHub Releases. For an existing direct install, run codewhale update (or codewhale update --check to inspect it). The updater prints the executable path and keeps newer builds.

The first run helps you connect a provider or configure Codewhale offline. Model replies require a connected hosted or local model. Codewhale also supports npm and Cargo as secondary packaging routes, plus Docker, Nix, Scoop, Android/Termux, and an optional CNB mirror. Existing package-managed installs receive migration instructions. See installation and PATH help.

Tab completion is one command per shell — codewhale completion bash|zsh|fish|powershell|elvish. See shell completions.

Use

Open a terminal in your project folder and run codewhale. Choose your provider with /provider and your model with /model. Then describe a concrete task:

Fix the failing tests and explain what changed.

Or run a task without opening the TUI:

codewhale exec "fix the failing tests and explain what changed"

Codewhale can read your repository, edit files, run commands, inspect results, and keep working toward a goal. Use /mode plan to explore without file changes or shell execution, and /mode work when you want it to make changes. Press Shift+Tab to choose Ask, Auto-Review, or Full Access; the modes and permissions guide explains what each allows.

Terminal, apps, and Computer Use

The terminal and graphical clients connect to the Codewhale Runtime, which runs the agent and its tools:

• Terminal: codewhale opens the interactive interface; codewhale exec runs a task from a script or CI job.
• Local browser: codewhale web opens the bundled local web client for the same runtime.
• Codewhale web and desktop apps: graphical workbenches in development. Their availability is listed on the product page.

Computer Use adds tools for observing and interacting with other applications. The plugin is included in the current source. Review its requested access and enable it before use; OS permissions and platform requirements still apply. See the included Computer Use guide and plugin setup.

For VS Code, the community-maintained CodeWhale extension connects to the local Runtime from a sidebar. Install it from the VS Code Marketplace; source code is on GitHub.

Why Codewhale

• Choose your models. Connect hosted providers or local models through Ollama, vLLM, or SGLang. Use /provider to change providers and /model to choose a model.
• Stay in control. Inspect proposed actions and resulting file changes. Approval settings govern when review is needed; Full Access still respects hard policy boundaries. /undo and /restore help recover workspace changes.
• Keep long work organized. Save sessions, set a durable /goal, review workflows before they run, and coordinate agents without turning their internal instructions into your transcript.
• Extend the agent you already have. Connect MCP servers and skills, configure hooks, and keep agent roles as readable files in your project or personal settings.

Run /help in the TUI for commands and keyboard shortcuts.

Safety

Codewhale runs on your machine with the access you grant it. Approval modes and repository rules limit what the agent may do; optional OS sandboxing adds a stronger execution boundary where supported. Unknown model prices stay unknown instead of being reported as free.

Read authorization order for the exact policy stack and configuration for local settings.

Project history

Codewhale began as deepseek-tui and still preserves that configuration and session compatibility. It is now provider-neutral and independently maintained; it is not affiliated with any model provider.
