Openmanus (Manus AI Open Source)(+16k Stars on Github in just 2 Days!

Openmanus is so popular, nowadays especailly for AI Agent Development Geeks!

What is Openmanus?

Openmanus is open source verion of Manus AI. The emergence of Manus AI has indirectly sparked a replication race in the open-source community. Within this wave of innovation, OpenManus was developed in just three hours by core contributors of MetaGPT, making it an ultra-fast, accessible alternative to Manus AI.

Unlike Manus, which requires an invitation code, OpenManus is fully open-source, allowing anyone to deploy their own AI assistant with just a few simple steps.

Openmanus: Intelligent Collaboration > Brains and Fun

This project wasn’t a solo effort—it was a collaborative achievement by developers from MetaGPT. The efficiency of these engineers is astonishing, as they built OpenManus faster than drinking a cup of coffee!

At its core, OpenManus features a modular Agent system, acting as a network of specialized teams that work together seamlessly:

• Project Manager (Manus main agent): Understands user needs and manages execution.
• Strategic Expert (PlanningAgent): Breaks tasks into actionable steps.
• Technical Experts (ToolCallAgent): Handles specific AI-powered operations.

This modular design allows customizable AI assistants, making OpenManus a flexible alternative to closed AI systems.

Openmanus: Task Handling with Precision

OpenManus is not just another AI tool—it meticulously breaks down complex tasks into structured processes. For example, if assigned to analyze a website for SEO optimization, OpenManus:

1. Collects website metadata
2. Analyzes SEO ranking factors
3. Identifies technical errors
4. Compiles an actionable SEO optimization report
