Langflow vs semantica
Langflow has 155,461 GitHub stars, 10,169 forks, 1,056 open issues and last shipped today. semantica has 13,619 stars, 1,561 forks, 120 open issues and last shipped yesterday. Langflow leads on adoption by 1,042% (155,461 vs 13,619 stars). Langflow is written in Python under MIT; semantica is written in Python under MIT. Langflow has attracted 7% as many forks as stars, semantica 11%. Langflow was the more recently maintained of the two, and both are self-hostable with no licence fee. The two share 1 topic tag (generative-ai), so they are genuine substitutes rather than adjacent tools.
Two open source projects, one decision. Both are free and self-hostable — the differences are community size, license terms, language stack and release pace.

About Langflow
Langflow is a visual builder platform for designing, testing, and deploying AI agents and retrieval augmented generation (RAG) pipelines. It lives in the Python based generative AI ecosystem and targets developers building intelligent applications. The project provides a low code interface to assemble components—such as LLMs, vector stores, memory modules, and tools—into executable workflows, while also exposing those workflows as APIs or MCP servers for integration into external applications.
