Company

Built by people who have watched too many green suites lie.

Handoff started from a simple observation: AI can drive a browser well enough to be useful, and not well enough to be left alone. The product is the supervision.

What we believe

  • Autonomy needs an interrupt. A test agent you cannot watch and cannot stop is a liability on a live system. The live view and the takeover are the product, not a debugging aid.
  • Determinism wins in CI. A model in the replay path adds cost, latency and variance, and a model's judgment should never gate a merge. Authoring is where the model belongs.
  • Your model, your data path. Running on your own key collapses our costs and keeps your pages with the provider you chose.
  • No lock-in. If the export is not good enough to leave with, it is not good enough.

How it is built

TypeScript throughout. A Fastify session broker owns the browser and the control lease. Temporal workflows hold the run's state, so a paused run costs nothing and a restarted worker resumes where it left off. Playwright's selector logic generates the locators; a lean accessibility-tree serialiser keeps observations small. Postgres with row-level security, Redis, S3-compatible storage and Chromium complete the stack. It runs on plain Linux servers.
