Deploy Flowise on CometVPS
Build AI agents, RAG pipelines, and chatbots visually — drag-and-drop LangChain and LlamaIndex without writing the boilerplate. Self-hosted, with every flow exposed as an API and embeddable widget.
What is Flowise?
Flowise is an open-source low-code tool for building LLM-powered applications. If you've ever wanted LangChain without the Python boilerplate, Flowise gives you a node-based canvas where every LangChain primitive — LLMs, retrievers, memory, tools, agents — is a draggable block.

Key Features
Everything you need to ship LLM apps faster
Visual Agent Builder
Drag-and-drop canvas for chaining together LLMs, tools, memory, and retrievers. Build agents and RAG pipelines without writing LangChain boilerplate.
Built-in RAG & Vector Stores
Native nodes for Pinecone, Chroma, Qdrant, Weaviate, Postgres pgvector, and more. Upload documents, embed them, and query them in a single flow.
100+ LangChain Nodes
Pre-built nodes for every popular LLM, tool, loader, splitter, and memory implementation. Anything missing? Drop in a Custom Tool or HTTP node.
API & Embed Ready
Every flow exposes a REST API and embeddable chat widget. Ship the same agent as a chatbot, a Slack bot, and an internal API in minutes.

Security Tip
Always set FLOWISE_USERNAME and FLOWISE_PASSWORD before exposing the editor publicly — without them, anyone who finds your URL can edit your flows and read the credentials inside them. Use Flowise's built-in credential vault rather than pasting API keys directly into nodes, and put it behind HTTPS.
Recommended VPS Plans
Pick a plan based on how many flows and how much data you'll be working with
Core VPS - Basic
2 vCPU Cores, 4GB RAM, 60GB NVMe
Comfortable for solo experimentation, prototyping a few RAG flows, and demoing chatbots without breaking the bank.
Supernova VPS - Flare
6 AMD Ryzen Cores, 16GB DDR5, 200GB NVMe
Faster Ryzen cores and DDR5 memory keep agent flows snappy and leave room for an embedded Postgres + vector store on the same server.
AstroMetal - AM-R5950X
16 Cores, 128GB RAM, 1.92TB NVMe
Dedicated horsepower for a team running dozens of concurrent agents, vector indices, and large document collections.
