OpenManus: Free Manus Alternative

Author / channel: WorldofAI Format: video Source: Original Published: 2025-03-09

Summary

Manus launched as a closed, waitlist-only “general AI agent” and went viral on X. Within days, the MetaGPT team shipped OpenManus (github.com/mannaandpoem/OpenManus) — an open-source clone of the agent loop without the polished UI. Walkthrough covers conda install, free model providers (Groq, Hyperbolic), and a weather-app demo with live animations. Notes OpenManus is materially slower than Manus and rougher but functional. Also references OpenManus-RL: an RL-based reasoning improvement project from the same team.

Key Points

  • Origin story — Manus AI shipped as a viral closed-beta general agent. OpenManus appeared within days from the MetaGPT team as an open-source equivalent. No UI, just the agent loop in Python.
  • Install path — conda env → clone repo → pip install -r requirements.txt → configure config/config.toml (rename from .example) → python main.py. Free LLM via Groq or Hyperbolic API keys (rate-limited but workable).
  • Capabilities — multi-step task execution, file manipulation, terminal commands, web research, CSV generation. Agent runs 30+ steps autonomously per task in the demos.
  • OpenManus-RL — sibling project from the same team focused on RL-based reasoning improvements for agent loops.
  • Honest caveat — slower than hosted Manus, less refined output. Useful as a baseline / hackable starting point, not a Manus replacement at parity.
