Understand your app as it actually behaves

Atlas turns evidence from builds, sessions, and tests into a living model of your screens, flows, transitions, changes, failures, and coverage.

Understand with Atlas

A model that never goes stale

Unlike diagrams and documentation that rely on manual upkeep, Atlas is grounded in runtime evidence generated whenever humans or agents use the application.

Atlas in Revyl: Finance App's screens laid out as a map, with a comment thread open on the Add expense screen
  1. 01

    See the whole application

    Map the screens and flows that exist in the running product.

  2. 02

    Track what changed

    Connect product changes to observed states and runtime evidence.

  3. 03

    Start every run smarter

    Give people and agents shared context before they explore, test, or develop.

How it works

Every run adds to the map

Atlas only shows what Revyl has seen. Each screen keeps the screenshots and reports it came from, so the map follows what actually ran on iOS, Android and web.

Every run leaves evidence

Tests, workflows, sessions and explorations add the screens they saw and the taps that moved between them, each tied to its screenshot and report.

  • Every run countsTests, workflows and sessions add the screens they reached.
  • Evidence stays attachedEach screen keeps the screenshot and report it came from.

Atlas chat

Ask how your app actually works

Ask a question in plain language. Atlas chat searches the map, follows transitions and inspects captures, then answers with an evidence canvas you can open and share.

  • Answers point to the captures and transitions behind them
  • It says when a path was observed and when it wasn't
  • Coding agents query the same map with revyl atlas

Design drift

See where the build drifted from the design

Paste a Figma file or frame link into Atlas chat. It pairs each design frame with the captured screen in the same state and writes up what differs, with both side by side.

  • Each difference is marked on the captured screen
  • States are compared only when the capture matches the frame's condition
  • A frame with no matching capture is reported as a coverage gap

Explore

Send explorers where tests haven't been

Explore launches parallel agents on devices against the build you pick. Each explorer takes a different path, and what it sees lands in Atlas as screens and transitions.

  • Pick the build, the number of explorers, a strategy and a time limit
  • Balanced, Surface sweep, Journey focus or Hard edges
  • Watch discoveries arrive, or cancel the run to release its devices
