Langflow的视觉RAG赌注：自有资金支持的Logspace打造了154k星工具，DataStax将其收购

做的是什么生意

Open-source, drag-and-drop visual framework for building RAG and GenAI application workflows, initially as a no-code GUI over LangChain.

启动资金：Self-funded — no venture round reported before the DataStax acquisition (undisclosed sum).

起因

Logspace was founded in January 2022 in Brazil by Rodrigo Nader and Gabriel Luiz Freitas Almeida, who had worked on machine learning at Bitvore. They self-funded the company as an ML consultancy, then released Langflow in March 2023 as an open-source no-code GUI for visually prototyping LangChain flows.

经过

Langflow spread quickly through GitHub and developer communities as the RAG wave hit. By the April 2024 acquisition, its community had grown past 15,000 developers on GitHub and 10–12 staff joined DataStax. After the deal Langflow kept operating as a separate entity, and growth accelerated: it crossed 100k GitHub stars on 2025-08-14 and reached about 154k by September 2026.

结果

DataStax acquired Logspace on 2024-04-04 for an undisclosed sum; Langflow continued as an independent team inside DataStax and kept climbing GitHub (100k stars in Aug 2025, ~154k by Sep 2026).
