Pick by what you have
- You have an agent and need many cheap sessions: simulators and emulators, here or at an agent-first cloud.
- You have an agent and need the device your users hold: shared real phones, here or at a device cloud with MCP.
- Your agent must live inside consumer apps: private devices with state, here or at a phone cloud with SIMs.
- You have phones in a drawer: open source, or connect them here when you want them next to cloud devices.
- You have no agent and want tests written for you: an AI tester.
