Tap

Our take

Taprun's compile-once model is a genuinely different take on browser automation: the AI inspects a site once and emits a deterministic .plan.json program (a 13-operation vocabulary you can git-diff), which then replays forever at zero LLM tokens inside your own logged-in Chrome — credentials never leave the machine by architecture — with a verify command that diffs snapshots to catch site drift. It ships as an MCP server over stdio or local bearer-authed HTTP via @taprun/cli, plus a Chrome Web Store extension and Playwright runtime, 70+ prebuilt taps, Homebrew and npx installs, CI, and bilingual docs; the owner is a 2012-vintage GitHub account, the most credible in this batch. Caveats: the repo holds the extension and packaging while the CLI pulls a ~30MB prebuilt binary, adoption is early (10 stars, ~880 npm downloads/week across 33 published versions), and deterministic replays inherently trade away resilience to page redesigns between verify runs. For agent users doing repeated logged-in tasks — dashboards, feeds, form flows — where paying tokens on every run is the actual problem.
