3. langflow

   2 53 155,458 10.0 Python

   Langflow is a powerful tool for building and deploying AI-powered agents and workflows.

   

   Project mention: Deploying Langflow: An Open-Source Visual Framework for Building AI Applications | dev.to | 2026-09-23

   Langflow is an open-source, low-code visual framework for building artificial intelligence (AI) agents, workflows, and retrieval-augmented generation (RAG) applications. Developers use its visual builder to assemble large language model (LLM) pipelines from prebuilt components and test them in an interactive Playground, and finished flows run as API endpoints or Model Context Protocol (MCP) servers without extra boilerplate code. This guide walks through self-hosting a production-ready Langflow instance on a Linux server with Docker Compose, covering PostgreSQL persistence, Traefik reverse proxying with automatic HTTPS certificates, authentication for the visual editor, and validation of the deployment through a RAG chatbot that answers questions from an uploaded document. By the end, you'll have a secured Langflow deployment running behind HTTPS with a working RAG chatbot proving that ingestion, retrieval, and generation all work end to end.

4. langchain

   3 104 147,605 9.9 Python

   The agent engineering platform.

   

   Project mention: Why does my vector DB retrieval keep returning duplicate noise for my chat agent, and how to fix it? | dev.to | 2026-10-07

   In langchain-qdrant, LangChain's lambda_mult reaches Qdrant as its diversity, so the direction flips, as an open LangChain bug report records. At 0.5 the two readings coincide; the trap opens when you move it.

5. MoneyPrinterTurbo

   4 4 129,737 9.6 Python

   利用 AI 大模型和自动化工作流，根据主题或关键词一键生成高清短视频。Generate HD short videos from a topic or keyword with an automated AI workflow.

   

   Project mention: Preventing Upstream Model Outages from Stalling MoneyPrinterTurbo Video Jobs | dev.to | 2026-09-09

   At 3:00 AM, upstream LLM gateway timeouts will quietly murder your batch video pipeline. You wake up to stalled worker threads, exhausted connection pools, and an orchestration queue frozen in limbo. When integrating an automated generator like harry0703/MoneyPrinterTurbo into production, the critical failure point is almost never FFmpeg or video rendering. The true vulnerability is client-side mishandling of transient upstream API degradation.

6. generative-ai-for-beginners

   5 15 121,057 9.6 Jupyter Notebook

   21 Lessons, Get Started Building with Generative AI

7. LLMs-from-scratch

   6 41 106,200 8.2 Jupyter Notebook

   Implement a ChatGPT-like LLM in PyTorch from scratch, step by step

   

   Project mention: What Building Redis, Git and an LLM From Scratch Taught Us About Using Them | dev.to | 2026-10-05

   RAG and agents. LLMs from scratch and Karpathy's Zero to Hero cover tokens, embeddings, attention. Chunking and retrieval choices stop being folklore.

8. OpenHands

   7 45 90,449 10.0 TypeScript

   🙌 OpenHands: AI-Driven Development

   

   Project mention: 300+ languages doesn't mean what you think: three tiers of code understanding | dev.to | 2026-08-08

   I am not the first person to look at this. aider evaluated stack-graphs and went with tree-sitter tags plus PageRank instead (#534). So did OpenHands (#742) and SWE-agent (#38). Three serious teams reached the same conclusion: too much work, unmaintained upstream, not worth it.

11. LobeHub

    9 20 83,080 10.0 TypeScript

    The ultimate space for work and life — to find, build, and collaborate with agent teammates that grow with you.

    

    Project mention: Show HN: AI Roundtable – Let 200 models debate your question | news.ycombinator.com | 2026-03-24

    You can set this up yourself with API keys to the corresponding providers and creating an Agent Group in https://github.com/lobehub/lobehub. Agent groups allow you to easily create a room of agents and have them discuss any of your topics. Easily make agents with types and skills, it even assists in drafting starting prompts and even team members depending what your query (and selected model) is.

    You can self-host as well, but not via desktop app. Sever setup required.

    Be careful of your token context, you can easily rack up costs if you leave Opus selected as the model and get lost in some rabbit hole of results.

    Enjoy enjoy!

It provides an SDK and service interfaces, and distinguishes between the open-source library, self-hosted deployment, and managed service. Mem0 project
