Register entry · Browser & computer use · updated 26 Sept 2026

Asteroid

Asteroid is a Y Combinator-backed (W25) browser automation platform engineered for high-stakes, regulated back-office workflows across legacy EHRs, payer portals, and government registries that lack APIs. It executes workflows inside isolated, ephemeral Daytona browser sandboxes, pairing autonomous navigation with explicit human-in-the-loop escalation gates, credential vaulting, and HIPAA compliance.

Evidence checks. Part of this entry came from a research batch that failed verification: only items confirmed at their source are used, and its trust grades and pros and cons are withheld. 1 item removed: dated before the thread it cites (1). How evidence is checked.

Editorial adjustment. Not independent reviews: a Y Combinator launch post written by the company, and a customer story on a vendor partner's site (QA of agy-2).
