Three separate headless browsers built for agents trended on the same day with three different engine strategies
jo-inc/camofox-browser (9,309 stars, JavaScript, patches Firefox at the C++ level to spoof hardwareConcurrency, WebGL, AudioContext and WebRTC before JS sees them), lightpanda-io/browser (34,635 stars, a from-scratch Zig DOM with V8 and html5ever via FFI) and browser-use/browser-use (112,862 stars, +231 today) all appeared on trending boards today. They are not competing on features but on what part of the stack they throw away: camofox keeps a real browser and hides it, lightpanda deletes everything a human needs, browser-use drives an existing one. Both camofox and lightpanda ship accessibility-snapshot or MCP output rather than raw HTML.
