Deploy Flowise on Your VPS
Deploy Flowise on your VPS in one click. A drag-and-drop builder for LLM apps and AI agents — visually wire chains, RAG pipelines, and chatbots, then expose them as an API.
Flowise is a visual builder for LLM applications. Drag and drop nodes to compose chains, RAG pipelines, and conversational agents on top of OpenAI, Anthropic, Ollama, and dozens of other providers — then expose the result as an API endpoint or an embeddable chat widget. It's the fastest way to prototype and ship AI features without gluing together LangChain code by hand.
Vessl deploys Flowise with a persistent volume for your flows, credentials, and API keys, and enough memory headroom for its Node runtime. Log in with the credentials from the deploy form and start building.

Frequently asked questions
Do I need my own LLM API keys?
Yes — Flowise orchestrates models but you bring the provider keys (OpenAI, Anthropic, etc.), or point it at a self-hosted Ollama instance. Keys are stored on the persistent volume.
Can I embed a Flowise chatbot in my site?
Yes. Every flow can be exposed as an API endpoint or an embeddable chat widget you drop into your website with a snippet.
Why does Flowise need more memory?
It bundles LangChain and a large Node UI, which needs roughly 2 GB of RAM to boot reliably. Vessl provisions this for you by default.
