OpenManus

FoundationAgents
open source / Overall score: 3.0

OpenManus is an open reimplementation of the Manus autonomous agent, built by members of the MetaGPT team as a general agent that needs no invite code. It performs tasks through tools and browser automation, supports MCP, and adds a data-analysis agent. It is framed as a product run from a clone rather than a reusable library.

Adoption

3 medium confidence
3.0

OpenManus is run from a git clone, and its PyPI package is vestigial with negligible use, so GitHub stars are the adoption signal here rather than package downloads. A star is not a use, so this reading reflects visibility rather than measured deployment.

Capability

3 medium confidence
3.0

OpenManus is a general agent with tool use, browser automation through Browser Use and an MCP mode, but it ships as a project run from a clone and publishes no benchmark results. OpenHands offers a broader, more battle-tested agent, so OpenManus sits two tiers below it.
