While browsing through your app did you want any fixes to be made later but then forgot about it... well, not anymore
Comment on a screen in Atlas and your coding agent fixes it • Pin a comment, tag it Polish • revyl skill install --name revyl-cli-atlas-review • Ask it to fix the open comments • It fixes the code, checks it on a cloud phone, replies with proof and resolves the thread

Computer
Mac computers are live on Revyl in experiments. Start a Mac in the cloud from Sessions or one CLI command, watch its desktop live in your browser, and get the recording and a step-by-step timeline when you stop.

nobody watches the full recording of a failed test now every Revyl session downloads one action at a time: a timeline of every step on the video, plus a short clip of each one

Web
Web is live on Revyl! Give Revyl a preview link or let it build your web app. Coding agents through the CLI, Proof of changes and the SDK all work there, and every session is saved into Atlas.

your app has a new screen. two, actually. iPhone Duo is now on Revyl: fold it mid-test and check both layouts ↓

passes on Android. fails on iOS. no idea why. our most common support message, so we recorded how we'd find it: same flow on both phones, then look for the exact step where they split ↓

the culprit was one line in the add-to-cart button: `if (Platform.OS === 'ios') return;`

🚨 ATTENTION ALL WEB DEVS 🚨 Revyl started on web. We moved to mobile because that's where the DevEx was furthest behind, and spent years making building mobile feel as good as web. Now we're bringing everything we learned back to web. Welcome home 🫡
Revyl does web now! Here's me verifying a UX change in Revyl: the full replay, every step, the logs, network and perf all on one timeline. I get why our customers love this shit xD

Prove your changes
The streets are saying that Verification is the bottleneck With Revyl Proof of changes, every PR runs on a cloud device and you get a verdict, screenshots, the recording and logs on the PR. It all gets saved into Atlas, so you can see what changed in the app vs main. And keep a record of all the work that has been done by your agents

tests that know your code break when it changes. tests that know your product keep passing
Durable Product Identity ⟣ The future of verification: contracts that represent the state space of what users can see and do. Rewrite the code. The contract still holds ->

Agent written PRs move fast and the real breakthrough is shipping proof that they work
Everyone agrees verification is the new bottleneck, but how to solve it is still up for debate Cloud agent adoption is growing quickly but still not the standard, inner loop vs outer loop validation, and what everyone actually cares about ↓

Self serve experiments, lots more coming
Experiments in Revyl are now self-serve. Before, you had to ask us to turn on early features. Now you can switch them on yourself in Settings → Experiments. The first two: • Web apps (alpha): use Revyl on your web app the same way you do on iOS and Android, with one Atlas across all three • A much faster computer use agent: tighter feedback loops, and cheaper, because we run some of the models on our own compute More coming this week.

Your users have an iPhone Duo. Now your agent does too. Test and fix Duo layouts in minutes on Revyl!
We gave Opus 5.5 an iPhone Duo. Everyone's racing to port their app to the Duo. Almost nobody has one on their desk. So the agent tests on a cloud Duo: unfolds it, sees the black bars, fixes the layout. 5 minutes later the app fills the screen ->
