Reliable Browser Trajectories for Repeatable Automation
Model browser work as observable, scheduled actions with bounded transitions and replayable evidence.

A flow is a sequence of decisions
Reliable browser automation observes state, chooses a permitted action, executes it, and records the transition instead of treating a session as one opaque script.
Scheduler-driven browser trajectories on fingerprint-hardened Chromium and Firefox, built for resilient, human-shaped automation.
Design for changing pages
Each action needs a readiness condition, a bounded result, and enough captured context to diagnose why the expected transition did not occur.
- Schedule each browser action
- Run a human-shaped Chromium or Firefox trajectory
- Replay cached flows on repeat runs
Replay only verified paths
Replay should remain conditional on the page state it was created for, and automation must stay limited to authorized workflows.
- Engine-level fingerprint defense on Chromium and Firefox
- Scheduler-driven per-action trajectories
- Flow-replay cache for faster repeat runs
