Browser tools
What this browser is, and what it can really do, read live from your own tab with every limitation stated. Nothing uploaded.
6 tools
- Browser report
Every identity field your browser volunteers, read live in this tab, caveats included.
- UA parser
Paste any user-agent string, see the browser, engine, OS, and device it claims.
- Capability dashboard
Which APIs this browser has: presence measured, permissions only queried, never asked.
- Feature support
A dated web-platform snapshot checked live, so you see where this browser agrees, leads, or lags.
- Screen & viewport
Screen, DPR, layout and visual viewports, orientation, preferences. Live values, fingerprinting labeled.
- Deep probes
Fonts, codecs, WebGL/WebGPU, storage, permissions: the five probes that need real work.
