StableBrowse
Agents start from zero on every run.
Most web agents read the current DOM, act, and forget. They have no reusable model of page meaning, workflow state, or the paths that worked last time.

Browser Infrastructure Layer
Browser Layer for AI Agents
Turn dynamic websites into structured execution graphs agents can navigate, query, and reuse across runs.

What we solve
Browser agents fail because they do not understand websites.
Small website changes trigger guessing.
A popup, renamed button, reordered form, or broken step can push agents into retries, stale assumptions, and misread page state.
Every mistake burns tokens and time.
Without a verified map of what to do next, agents over-query pages, repeat actions, and spend expensive model context on browser mechanics.
Engineering
Websites become reusable execution graphs.
Switch to the view to see the live structure.
Persistent site memory
StableBrowse learns how a site works once, then gives every future agent run a reusable model of pages, state transitions, and successful paths.
Knowledge graphs
Page semantics, DOM anchors, forms, actions, and internal endpoints are encoded into a graph instead of sent as raw HTML.
Execution patterns
Repeated workflows become verified routes. When the UI shifts, agents can recover through known state, endpoint, and action patterns.
Use cases
Built for repetitive web work.
Form filling, custom data indexes, repetitive tasks, and workflow automation all run better when agents have a memory of the website.
