Sentinel
AI browser automation runtime that executes natural language goals, handles clicks, extracts structured data, and self-heals selectors when pages change
The product is an AI browser automation runtime that is a drop-in companion to Playwright, letting users describe goals in natural language to handle clicks, extract structured data, and cache selectors that self-heal when pages change. It is for software developers and engineering teams in B2B organizations building automated browsing, testing, and scraping workflows. It is positioned as 40x cheaper than Stagehand, open source under MIT, and designed to use fewer tokens per action while surviving site redesigns.
