Browser Agent: Autonomous Multi-Modal Chromium AI Navigation with FastAPI, Playwright, and Gemini

Q: What is Browser Agent and who created it?

Browser Agent is an autonomous AI web browsing system built by Aswath Karthikeyan (Founder of CrypVorex and PSG Tech engineer). It drives Chromium browser sessions via Playwright, FastAPI, Gemini API, and browser-use to perform end-to-end web tasks.

Q: How does Browser Agent reduce LLM token context?

Browser Agent extracts the browser accessibility (a11y) tree rather than transmitting raw bloated HTML markup, indexing interactive elements and reducing token consumption by up to 80% while enhancing reliability.

Q: Can Browser Agent be self-hosted?

Yes, Browser Agent is completely self-hosted using Python FastAPI on the backend, Playwright for browser orchestration, and free-tier Gemini API keys without requiring paid cloud infrastructure.
