- Distributed workflow orchestration for test execution across pools of devices.
- Android and iOS device infrastructure across emulators, simulators, real devices, streaming, and automation.
- The CLI that ties local development to cloud verification through build uploads, live device sessions, and CI integration.
- OpenTelemetry integration, trace correlation, and execution-debugging tools.
- Real-time execution UX through WebSocket streaming, live device views, and graph-based test visualization.
- Product surfaces across the CLI, web application, and CI integrations.

About Revyl 02 / COMPANY We are building the mobile development platform.
Revyl is the mobile development platform where teams and AI agents build, develop, test, and understand mobile applications against the real, running app.
Cloud compute and devices power the work; replayable evidence proves the result; Atlas turns every run into durable application context.
The founding team created DragonCrawl at Uber AI and left to commercialize their work. Revyl is backed by Felicis, General Catalyst, and Y Combinator, with support from the co-creator of OpenTelemetry and operators from Meta, Nvidia, and Uber.
