- Fully open-source and reproducible from public source code
- Same engine available self-hosted, containerized, or hosted in cloud
- Drop-in replacement for Playwright and Puppeteer with minimal code changes
- Cross-realm consistency with agreement between main thread, workers and iframes
| - Works with any existing MCP server you already have configured without requiring migration or special catalog registration
- Detects and alerts when servers change what they tell your model between health checks
- Completely local with no cloud sync, no account, and no upload of configuration or API keys
- Public source code under MIT License so you can audit every request or build from source yourself
- Automatic timestamped backups before every change with the ability to browse and restore earlier versions
