CodeWhale is an open-source coding agent for the terminal that lets developers bring their own AI model or provider. Given a task, it can inspect a codebase, edit files, run commands, verify its work, and continue until the task is complete or human input is required. The project was originally built around DeepSeek but has evolved toward a provider-neutral coding harness that supports both open and hosted models without giving one vendor privileged treatment.

Written in Rust and designed to run locally, CodeWhale can be used interactively through a terminal UI or non-interactively in scripts and CI pipelines. Developers can switch models during a task and integrate the agent into existing command-line workflows rather than moving to a dedicated AI IDE. It is especially appealing to users who want an open, model-flexible alternative to proprietary coding agents while retaining control over execution on their own machine.
