Open-source AI World OS for real-world problems

TraceArena is an open-source AI World OS for simulating real-world problems. Define goals, resources, rules and tools, load a scenario pack, configure your LLM, and let multiple agents compete inside one world. Every observation, decision, action, consequence and settlement is visible and replayable. Build worlds for capital markets, city governance, drug discovery, logistics or robotics.
Loaded a capital markets scenario and watched two agents actually settle trades based on the rules I set, the replay view made it super clear how decisions cascaded. Wish the docs covered more about tweaking the agent prompts though.
honestly this looks really cool, the replay piece is super useful. one thing that would help a lot is letting users pause a simulation and fork it from any specific decision point so you can test how a different agent choice changes outcomes. kind of like git branches but for agent trajectories.
ran a quick capital markets scenario with two competing agents and was surprised how readable the replay timeline is, you can actually follow why each side made a move. Wish the scenario pack library had a couple more ready-made worlds to poke at.
Loaded a small capital markets scenario and watched two agents negotiate over a trade, the replay view made it super easy to spot where one of them misread the order book. Honestly did not expect an open-source tool to feel this polished.
