Open-source control plane for orchestrating coding agents
Run Claude Code, Codex, Antigravity, OpenCode, Cursor and Grok sessions side by side in one workspace.
No resold tokens or quota caps — connect the credentials and plans you already pay for, and switch models mid-thread.
Manage branches, automate commits and pushes, and handle pull requests with inline diff review before accepting changes.
Open-source and MIT licensed, so you can run it on your own infrastructure and modify it for your team.

GPT-powered test idea generation and script creation inside your browser
Generate comprehensive test ideas for a page by analyzing its elements with OpenAI language models, then refine them before use.
Convert a selected test idea into a runnable script for Playwright, Selenium or Cypress, choosing your preferred language from JavaScript, TypeScript, Python, C# or Java.
Scan the page under analysis for accessibility problems and get actionable suggestions to make the application more inclusive.
Turn AI-generated test ideas directly into automation and edit them along the way so generated scripts match your intended scenarios.
