Semaloop vs Revyl
Revyl is a mobile platform pairing vision-based tests with observability and a map of your app. Semaloop runs plain-English tests on real iPhones and Android emulators against every build you ship.
What Revyl is
Revyl runs iOS and Android apps on cloud devices, takes natural-language tests with no selectors, and pairs each run with observability — step traces, network, state diffs — plus Atlas, a living map of your app’s screens and flows. It also exposes a Python SDK for programmatic control. Of everything here it sits closest to us.
Where they differ
| Semaloop | Revyl | |
|---|---|---|
| Test authoring | Plain-English specs | Natural-language tests, no selectors |
| Centre of gravity | Regression on every build | Observability and a map of app behaviour |
| Programmatic control | MCP server and REST API | A Python SDK |
| Deciding pass or fail | A separate judging step against the spec | Run evidence you gate on |
| Non-visual checks | Audio output is in scope | Vision-based |
Choose Revyl if
- You want a behavioural map of the app as much as a pass or fail, and will act on run evidence yourself.
- A Python SDK fits how your team wants to drive things.
- Their device coverage lines up better with your matrix — worth checking directly, since both products move quickly.
Choose Semaloop if
- You want a verdict you can trust without reading the trace, with the trace there when you need it.
- Audio, permissions, push and in-app purchase flows are part of what you need covered.
- You want to model your bill yourself before speaking to anyone.
