unbrowse
by unbrowse-ai
API-native agent browser powered by Kuri (Zig-native CDP, 464KB, ~3ms cold start). Unbrowse is the intelligence layer — learns internal APIs (shadow APIs) from real browsing traffic and progressively replaces browser calls with cached API routes (<200ms). Three paths: skill cache, shared route graph, or Kuri browser fallback. 3.6x mean speedup over Playwright across 94 domains. Full Kuri API surface exposed (snapshots, ref-based actions, HAR, cookies, DOM, screenshots). Free to capture and index; agents earn from mining routes for other agents.
