MobileGym

A simulation platform for mobile GUI agent research that provides a verifiable and highly parallel environment, solving the problem of unreliable evaluation and costly training on real devices. It targets researchers and developers working on mobile GUI agents, including those at academic institutions and AI companies. The platform is positioned as an open-source, browser-based simulator that enables deterministic evaluation and online RL training, with a structured state representation that supports batch-parallel GRPO and high sim-to-real transfer.

Key features

• State Builder with live injection
• Snapshot and restore simulator state
• Simulate device language, time, battery, location
• Inject messages, contacts, bills, SMS, tickets, weather
• Run agents with built-in or custom vision endpoints
• Supports AutoGLM and generic agent templates
• Batch-parallel GRPO training support
• Programmatic state judges for verifiable evaluation
