What StableBrowse does
StableBrowse is a browser infrastructure layer for AI agents, backed by Y Combinator. It turns dynamic websites into structured execution graphs that agents can navigate, query, and reuse across runs, so agents don't have to re-learn a site or parse raw HTML on every visit.
Key capabilities
- Site memory: reusable models of websites that persist knowledge across runs
- Knowledge graphs encoding page semantics, forms, and actions instead of raw HTML
- Verified execution patterns that help agents recover when a UI changes
- Reported reductions in token usage and faster execution versus raw browsing
The company states it is pursuing SOC 2 and HIPAA compliance for enterprise and regulated workflows.
Who it's for
StableBrowse targets engineering teams and enterprises building agents that automate repetitive web workflows, including insurance quoting, healthcare provider lookup and scheduling, mortgage applications, and e-commerce purchasing. As AI infrastructure, it serves developers who need reliable, lower-cost web automation in production.
