🚨 A developer built an AI engine that simulates thousands of people to predict the future.
It's called MiroFish.
You upload a news article, policy draft, or financial report and it spins up a full parallel digital world with thousands of AI agents that have independent personalities, long-term memory, and behavior logic.
Then you watch society evolve and get a full prediction report.
100% Opensource.

OpenClaw launched Jan 2026 and went from 9k → 247k GitHub stars in days.
Here's every alternative, heaviest to lightest 🧵
OpenClaw (TypeScript)
github.com/openclaw/openclaw
The one that started it all. Went from 9k → 247k GitHub stars overnight. Does everything — memory, tools, scheduling, 20+ messaging apps. The problem? It's massive, slow, and once caused a $400k accidental wire transfer.
> 430,000 lines of TypeScript
> Uses 1.5 GB RAM
> CVSS 8.8 security exploit
100% Open Source.
Here's every alternative, heaviest to lightest 🧵
1. Nanobot (Python)
github.com/HKUDS/nanobot
OpenClaw has 430,000 lines of code. This has 4,000. Built by Hong Kong University researchers so you can actually read and understand every line yourself.
> ~100 MB RAM
> Telegram, Discord, WhatsApp, Gmail
> Full memory + tools included
100% Open Source.

2. NanoClaw (TypeScript)
github.com/qwibitai/nanoclaw
OpenClaw once caused a $400k accidental wire transfer. NanoClaw was built directly in response — every agent runs in its own locked container. It physically cannot touch your files without permission.
> Docker/microVM isolation per agent
> WhatsApp, Telegram, Slack, Discord
> Now officially partnered with Docker

7. TinyClaw
github.com/machinae/tinyclaw
Not a personal assistant. A team of AI agents. One agent writes code, another reviews it, another deploys it. They hand work off to each other automatically you just describe the goal.
> Multi-agent chain execution
> Each agent runs in its own isolated workspace
> Zero manual handoffs
100% Open Source.
