RL Playground vs My OpenCrab

RL Playground is a one-of-a-kind interactive experience to explore reinforcement learning through play Agents don’t fake learning here — they actually learn, locally, on your device. No cloud, no servers, no precomputed simulations. You can watch learning happen live, episode after episode. Each level is based on a concrete scenario: a drone learning when to jump over a gap, an autonomous car learning to avoid pedestrians, a Duck Hunt–inspired challenge focused on tracking and decision-making. You can tweak learning parameters, train the agent, then test it and observe how its behavior evolves over time. RL Playground is made for: people who want to understand AI hands-on, curious minds, students, developers, and players looking for experimental, meaningful games. No internet required. No prior ML knowledge needed. Just learning by doing.
