# What is Revyl?

> Mobile infrastructure for agents and humans

Revyl gives you real iOS and Android devices in the cloud, an AI agent that tests your app using natural language, and the tooling to run it all in CI. No selectors. No scripts. No maintenance.

* **Real devices on demand**: spin up iOS simulators and Android emulators, stream them to your browser, tap and swipe like you're holding the phone
* **AI that understands your app**: describe what to test in plain English and Revyl's agent figures out the rest, even when the UI changes
* **Built for pipelines**: export tests as YAML, trigger from GitHub PRs, get Slack alerts, run everything from the CLI or API
