Obscura

Obscura is an open source, headless browser engine that runs isolated browser sessions for AI agents and web scraping.

Obscura is a headless browser engine built for AI agents and web scraping. It provides clean, isolated browser sessions in milliseconds without the memory and CPU overhead of standard Chrome instances. The software eliminates state bleeding between tasks by ensuring every session is a fresh sandbox with no shared cookies or cached data. It works with existing automation tools by supporting Playwright and the Chrome DevTools Protocol. Users can connect via API key to run managed sessions or self-host the engine using a single Docker container.
