Live sessions get checked against your existing test suite, automatically 🔥

When real production traffic matches a step in one of your UI Workflow Flows, UI Monitoring doesn't stop at reporting a match. It now runs the exact checks you already defined for that step, against what actually happened in that live session, not a synthetic re-creation of it. The same quality bar your test suite already holds your app to now gets applied to real user behavior automatically, with the actual screenshot and reasoning behind each result.

More reliable, more accurate matching

This only means something if a session is being matched to the right step in the first place, so a lot of this week went into exactly that. Sessions now evaluate within a couple of minutes of activity settling, instead of needing to wait for a session to fully end. And Flows now build up a learning period from repeated runs: which content on a page is structural (the same every time) versus incidental (recommendations, search results, anything that varies), so matching keeps recognizing a state as itself even as its incidental content changes. This update takes that further: when two states are similar except for how much content they have, matching now learns each one's typical content volume too, so it can tell them apart even when the specific content is something it hasn't seen before.

See what's been learned, right in the Graph tab

Nodes now display a meaningful label (the action that reached them) instead of generic, hard-to-tell-apart text, and each one shows whether its matching has fully stabilized yet, so a state showing "no match" can be told apart from one the system just hasn't seen enough real traffic to learn confidently yet.

Reset Test & Monitoring History

A new option in Project Settings → General clears a project's generated history: test runs, collection runs, API and UI Monitor telemetry, flow-graph state, while leaving everything you've authored (suites, contexts, environments, collections) untouched. Useful for starting a clean measurement window without losing your setup.
