Flowise

Project status: Flowise has been discontinued. Active development stopped in July 2026, the GitHub repository was archived on August 13, 2026, and official support ended on August 31, 2026. The Apache 2.0 source remains available to self-host or fork.

Flowise is an open source, low-code platform for building AI agents and LLM-powered applications through a visual, drag-and-drop interface — think of it as "AI LEGO." Instead of starting from code, you assemble chatbots, RAG pipelines, and multi-agent workflows by connecting nodes on a canvas, then deploy them as APIs or embedded chat widgets. With more than 55,000 GitHub stars, it became one of the most popular projects in the AI agent builder space.

Flowise offered three builders for different levels of complexity:

• Chatflow — flexible chatbots and single-agent workflows using advanced RAG, retrievers, and rerankers
• Agentflow — multi-agent orchestration with branching, loops, parallelization, and hierarchical logic
• Assistant — beginner-friendly agents that follow instructions, use tools, and answer questions from uploaded files

Core features include:

• 100+ integrations with LLM providers, vector stores, tools, memory, and external services
• A visual canvas with branching, looping, custom code, and logic routing
• Observability through execution logs, visual debugging, and external log streaming
• API access to every flow, plus JavaScript and Python SDKs, a CLI, and auto-generated Swagger docs
• Embedded chat widget, template marketplace, and reusable components
• Enterprise features such as SSO, RBAC, encrypted credentials, rate limiting, and scaling for high-throughput workloads

Under the hood, Flowise is a TypeScript monorepo: a Node.js backend that executes flows and serves them over REST, a React frontend for the drag-and-drop editor, and a components package containing the third-party integration nodes.

Self-hosting options:

• npm — install with npm install -g flowise and run npx flowise start (requires Node.js ≥ 20), then open http://localhost:3000
• Docker — a standalone image and a docker-compose setup ship with the repository
• One-click templates — AWS, Azure, GCP, DigitalOcean, Railway, Render, Hugging Face Spaces, and others
• A hosted Flowise Cloud offering was also available

Flowise launched in 2023, was backed by Y Combinator, and grew a user base spanning indie makers to enterprises. After end of life, the core team ships no further updates or security patches — if you rely on Flowise today, plan to run your existing self-hosted instance as-is, maintain a community fork, or migrate to another open source agent builder.
