       | Hey Hacker News, I'm excited to share LangManus, an open-source
       | project that's all about community-driven AI automation. Built on
       | the shoulders of amazing open-source work, LangManus combines
       | language models with specialized tools to tackle tasks like web
       | search, crawling, and Python code execution--while giving back to
       | the community that inspires it. At its core, LangManus uses a
       | hierarchical multi-agent system, where a supervisor coordinates a
       | team of specialized agents to handle complex workflows. It
       | integrates with LLMs like Qwen and powers up with tools like
       | Tavily for search and Jina for crawling. Plus, it comes with
       | Docker support and a web UI to make interaction a breeze. Want to
       | see it in action? Check out the demo video:
       | https://youtu.be/sZCHqrQBUGk. In it, LangManus calculates the
       | influence index of DeepSeek R1 on HuggingFace using a fully
       | automated plan--think web searches, data retrieval, and Python
       | code crunching, all seamlessly tied together. Here's what makes
       | LangManus stand out: Multi-Agent Magic: A supervisor delegates
       | tasks to agents like Researcher, Coder, and Browser for efficient
       | execution.
       | 
       | Tool Integration: Web search with Tavily, neural search with
       | Jina, and Python REPL for coding on the fly.
       | 
       | Ease of Use: Docker-ready and a web UI for quick setup and
       | control.
       | 
       | If you're into AI automation, multi-agent systems, or just love
       | contributing to open-source projects, swing by the GitHub repo:
       | https://github.com/langmanus/langmanus. Dive into the code, play
       | with the demo, or drop some feedback--we'd love to hear from you.
       | Join the community and let's build something awesome together!

         | Let me know if we can help with something at Hyperbrowser.

         | How do you think about core business logic (or at least,
         | _significant_ business logic) being embedded within prompts
         | like here:
         | https://github.com/langmanus/langmanus/blob/main/src/prompts...
         | 
         | Do you think or worry about not-being able to test these
         | things? (Or is that just me :))
         | 
         | Details: I ack/understand this comes from a dependency (ReAct
         | agents); not directly langmanus.
         | 
         | But, still, curious what the community/hn-tech thinks of
         | testability, veracity, potentially conflicting or overlapping
         | instructions across agents, etc, wrt "prompts" as sources of
         | logic. Ack its a general practice with LLMs.

           | Thought the logic was going to go with cpu and inference
           | related tasks will use GPU.

       | showing the step-by-step process from initial Git clone to
       | completed successful run.

       | You should probably change the name, I thought it was associated
       | with Manus usually projects like this will specifically have in
       | the tag line "An Open Source alternative to X."
       | 
       | Other than that looks very cool, reading through the code now. A
       | lot of these projects very heavily lean on Browser Use.

       | much for this - great resource.

       | Since "Manus" is a registered trademark, you should probably
       | change the name as quickly as possible to avoid legal issues with
       | the original trademark holder. At the very least, you could
       | remove the "M" to avoid directly copying it while still
       | maintaining recognizability.
