Axolotl

By Axolotl QA. Category: IDE and repo test agents. Homepage

The Axolotl GitHub README describes it as an Apache-2.0 open-source VS Code extension, built on Cline, for testing code changes in web applications. It reads a pull request diff, uncommitted changes or selected files, generates test cases and runs them in a built-in browser. Users can also describe what to test in the chat box. Tests are regenerated on each run, and the extension uses the user's own Anthropic API key. A copy fix prompt option writes a Markdown hand-off for agents such as Claude Code, Cursor or Codex CLI. The Visual Studio Marketplace lists it as free.
