Phonebox

Phonebox provides developers with virtual Android phones accessible in the cloud, specifically engineered for operational agents. This platform unlocks innovative operational sequences by allowing agents to interact with applications directly, even those lacking comprehensive or complete APIs. It also facilitates thorough testing of SDKs before public release. Key features include: direct interaction with Android apps, screen reading capabilities for agents, input simulation (tap, type, swipe), and the ability to install apps or manage files. Agents can also modify device settings like location or language. Phonebox supports integration with various coding agents such as Claude Code, Codex, or Cursor, alongside custom-built agents. The platform offers live monitoring of agent activity on the virtual device. User accounts and installed applications persist across sessions, ensuring continuity and efficiency. Devices are "parked" when not in use, incurring no cost while retaining their configuration for future access. Access is available via MCP, CLI, SDK, or a REST API, providing flexible integration options. This tool is ideal for developers, quality assurance teams, and businesses aiming to extend the capabilities of their agents to mobile environments for tasks like app interaction, user journey simulation, and comprehensive software testing.
