PyPI `langflow` (HTTP 200). Visual authoring plus source-access Python components, playground, and batteries for major LLMs/vector DBs. Built-in API and MCP servers turn workflows into tools other agents can call.","theCatch":"★155k: a large, mature project, but stars still are not a quality signal. Vs Dify / n8n / mcp-agent: Dify is OSS+cloud LLM studio; n8n is fair-code general automation; mcp-agent is an agent framework — Langflow’s catch is the agent/RAG visual builder with first-class MCP tool export. Self-host ops and dependency weight are real; pin OSS deploy docs before promising zero-ops.","verdict":"MIT visual agent builder when flows must ship as API/MCP tools — not Dify’s studio lane alone and not n8n general automation.","addedAt":"2026-10-01","featured":false,"domain":"AI Agents","subSpecialty":"Orchestration","subcategory":"Orchestration","tags":["mcp","api","self-host","permissive","workflows","active","fast-stars"],"capabilities":["agents","workflows","mcp"],"surfaces":["MCP","API","Self-host"],"ecosystem":["Python","Multi-platform"],"licenseModel":"Open-Core","githubStars":155817,"starsPerWeek":808,"access":"free","archived":false,"repo":{"createdAt":"2023-02-08","pushedAt":"2026-10-19","license":"MIT","archived":false,"checkedAt":"2026-10-19"}},"related":[{"slug":"claude-code","name":"Claude Code","tagline":"Terminal-first coding agent with deep repository context"},{"slug":"cursor","name":"Cursor","tagline":"The AI-first code editor that understands your codebase"},{"slug":"devin","name":"Devin","tagline":"Autonomous AI engineer for defined engineering tasks"},{"slug":"stagehand","name":"Stagehand","tagline":"AI-native browser automation that mixes code and natural language"},{"slug":"browser-use","name":"Browser Use","tagline":"Open-source framework for LLM-driven browser agents"}],"links":{"self":"/api/gems/langflow","html":"/gems/langflow","markdown":"/gems/langflow.md","category":"/api/gems?category=agents","categoryPage":"/stacks/agents"}}
