Langflow (langflow.org) Review

Langflow is an open-source, Python-based platform for visually building and deploying AI agents, retrieval-augmented generation pipelines, and MCP servers. Its node-based editor composes models, vector stores, tools, and agents, and every flow is exportable as code for version control and custom deployment. Being MIT licensed and self-hostable, it is free to use without an account, and it exposes a REST API and SDK for integration. Langflow suits developers and data teams who want a low-code starting point for agentic applications while retaining full ownership of the underlying code and infrastructure, without vendor lock-in or per-seat fees.
