About Flowise
Flowise is an open-source visual builder for creating LLM-powered chatbots, agents, and workflows — connect nodes for models, vector databases, and tools on a canvas rather than writing orchestration code by hand. The self-hosted core is fully open source, so you can run your own agent infrastructure without depending on a third-party platform.
Key Features
- Drag-and-drop visual flow builder
- Pre-built templates for RAG, chatbots, and agents
- Connects to OpenAI, Anthropic, local models via Ollama, and more
- Deployable via API, SDK, or embeddable chat widget
- Self-hostable on your own infrastructure
Best For
- Building a custom chatbot or RAG app without writing orchestration code
- Prototyping AI agent workflows visually before committing to custom code
- Self-hosting agent infrastructure for data-sensitive use cases
Pros
- Core is genuinely open source (Apache 2.0)
- No-code/low-code — accessible to non-engineers
- Model-agnostic, avoids vendor lock-in
- Free self-hosted tier with no usage caps
Cons
- Some enterprise features (identity/workspace management) are commercially licensed, not part of the open core
- Visual builders can get unwieldy for very complex workflows
- Self-hosting requires your own infrastructure and maintenance
