MobileGym is a simulation platform for research on mobile GUI agents. Instead of driving real phones or heavyweight Android emulators, it re-implements mobile applications as browser-hosted simulations whose internal state is fully programmable and readable. The release ships 28 simulated apps and 416 parameterized task templates, each paired with a code-level judge that inspects application state directly, so success is verified deterministically in well under a millisecond rather than by screenshot comparison or an LLM grader. Because each instance is a lightweight browser context, the platform reports running 256 parallel instances on a single server at roughly 400 MB of memory and about three seconds of cold start per instance, which makes large-scale rollout collection practical. The repository contains the simulator itself, a benchmark suite of test tasks with a published leaderboard covering several vision-language agents, and online reinforcement learning training code under mobilegym-rl. The authors document a sim-to-real study in which a GRPO run on a small vision-language model gains a large margin in simulation and retains most of that gain when the trained policy is moved to a physical device. The codebase is split between TypeScript for the simulated applications and Python for the agent, evaluation and training side, and it documents how to add new apps and task templates so the environment can be extended. It targets researchers training or evaluating GUI agents who need reproducible, parallel and safe environments, and it comes with a paper preprint, a project site and a live demo.
