Browser4

an open-source browser engine for agents and concurrency. Browser4 — an AI-native browser engine for autonomous agents, intelligent extraction, and large-scale web automation. The motivation came from a recurring frustration: most browser automation tools (Playwright, Selenium, Puppeteer) are excellent for human-written scripts , but start to show friction when used as a core execution layer for AI agents or at very high concurrency.
