Show HN: SandBox – AI agents simulating possible futures

https://github.com/abozaralizadeh/SandBox
4•lilistar•4mo ago
Hi HN, I’ve been working on SandBox, a project that lets you explore possible futures using autonomous AI agents. You can build scenarios (environmental, social, governance, etc.), make decisions, and see how things might unfold under different paths.

Some of the things you can do:

Generate speculative news and events under your scenario settings

Visualize how small decisions ripple over time

Run multiple agent-based simulations in parallel

Built with Python, LangGraph + Azure OpenAI, plus a front-end for visualization. Still in active development; feedback, critiques, ideas & contributions are very welcome.

Live demo: https://sandboxes.live/ Github: https://github.com/abozaralizadeh/SandBox

If you like it, a helps me know this is worth pushing further. Thanks!
