What is browser execution layer?
A browser execution layer takes a natural-language goal and produces reliable, repeatable action against live pages. It bundles the page compiler, the planner, the skill cache, deterministic replay, the credential vault, human handoff and session recording behind one authenticated API, so a caller ships a goal rather than a browser.
Why it matters
Without one, every team rebuilds the same brittle glue between a model and a browser and pays the model on every run. Consolidating it — and putting a semantic cache on top — is what turns ad-hoc agent scripts into automation whose cost falls with scale.
