# What is Revyl?

> Mobile infrastructure for agents and humans

Revyl gives you cloud iOS simulators and Android emulators, an optional AI agent
that tests your app using natural language, and tooling to run it all in CI.
Use the managed testing experience, or build your own workflows directly on
the device infrastructure.

* **Device infrastructure on demand**: spin up iOS simulators and Android emulators, stream them to your browser, and control them from your own scripts or agents
* **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
