Flowise
Open source visual builder and hosted platform for AI agents, chatbots and RAG pipelines, with drag-and-drop nodes, vector storage and hosted tiers for teams that prefer not to self host.
Overview
Flowise lets you design and run agentic apps without wiring every component by hand. The open source project provides a visual canvas with nodes for LLMs, tools, memory and vector stores so you can assemble chatbots, retrieval pipelines and assistants. You can self host with Docker or deploy to cloud infrastructure, while the hosted service offers a managed option with quotas, storage and support.
Developers bring their own model keys and connect data sources to ground answers. Teams adopt Flowise to prototype quickly, share flows and promote the reliable ones into production. Pricing for hosted plans starts low, and the community edition remains free, which makes experimentation accessible.

Capabilities
Visual Canvas
Assemble flows from nodes for LLMs, tools, memory and retrievers so you can test ideas in minutes.
Vectors and Data
Connect document loaders and vector stores so answers cite sources and reduce hallucinations.
Self or Hosted
Run with Docker on your infra or pick a hosted plan with quotas, storage and first month free offers.
API and Widgets
Expose flows as endpoints or widgets and version them for promotion into production.
Frequently Asked Questions
Is the project open source and can I self host without fees?
Yes, Flowise is open source with a community edition that you can run locally or on your servers. Hosted plans are optional for teams that want support and managed infra.
What does hosted pricing start at and what limits apply?
The Starter hosted plan begins around 35 per month and includes generous predictions, storage and support, with higher tiers offering more capacity.
Can I bring my own model keys and choose providers?
Yes, you connect your own model keys, which gives control over costs and the ability to switch providers as pricing or quality changes.
How do I connect my documents and make answers trustworthy?
Use loaders and vector stores to index PDFs, sites and knowledge bases, then reference sources in answers to improve reliability.
Is there an API so I can embed a Flowise build in my app?
Yes, paid hosting exposes API endpoints and widgets, and self hosted users can publish services behind their own gateways.
What is the best path from prototype to production in Flowise?
Iterate on the canvas, add evaluations, version flows and promote stable builds. Use logs and quotas to safeguard costs at launch.
