Flowise

App in the BluixApps catalog

What it is

Flowise is the low-code drag-and-drop builder for LLM applications — chatbots, agents, RAG pipelines, document-Q&A — built on top of LangChain. Visual canvas where you wire nodes (LLM, vector store, retriever, tool, memory) into a runnable flow, then expose it as a REST API or embeddable chat widget.

If LangChain is the framework, Flowise is the IDE.

What it's for

  • Customer-facing chatbots — embed a Flowise-built bot on your marketing site in minutes
  • Internal RAG over docs — drag a PDF loader → embedder → Qdrant retriever → LLM, deploy in an afternoon
  • AI agent prototyping — visually wire tool-using agents (web search, calculator, custom HTTP)
  • API-as-a-product — turn a flow into a versioned /predict endpoint with API-key auth
  • Education & demos — teach LangChain concepts visually before going to code

Who it's for

  • ML engineers prototyping LangChain pipelines visually before refactoring to code
  • Solo developers shipping AI-powered features without writing the chain orchestration themselves
  • Education / training providers teaching RAG + LLM concepts to engineers via visual flows
  • Agencies building customer-facing chatbots for clients quickly with embeddable widgets
  • Product teams exposing AI logic as an API endpoint without standing up a Python backend

Why teams pick Flowise over alternatives

  • LangChain-native — every node maps 1:1 to LangChain primitives, no abstraction tax
  • Multi-tenant marketplace flows — share/import flows as JSON
  • Embeddable widget<script> tag for marketing-site bots
  • API-key auth + rate limiting built in
  • 30+ vector store integrations (Qdrant, Chroma, Weaviate, Milvus, pgvector, …)
  • MIT license, Apache 2.0 dependencies — clean for commercial use

Integrations

  • Vector stores — Qdrant, Chroma, Weaviate, Milvus, pgvector, Pinecone, MongoDB, Redis
  • LLM providers — OpenAI, Anthropic, Cohere, Hugging Face, Mistral, Ollama, custom OpenAI-compatible
  • Document loaders — PDF, DOCX, web scrapers, GitHub, Notion, S3, Confluence, Airtable
  • Embeddings — OpenAI, Cohere, Hugging Face, local sentence-transformers, FastEmbed
  • Agent tools — web search (SerpAPI, Brave), calculator, code interpreter, custom HTTP, MCP servers
  • Embeddable widget<script> tag with token-gated access for marketing sites
  • Webhook + REST API — every flow becomes an authenticated /predict endpoint

Notable users & community

  • 35k+ GitHub stars
  • Featured in "production LLM stack" articles on Towards Data Science, Medium AI publications
  • Active Discord, weekly releases, strong RAG-tutorial pipeline
  • Common pairing with Qdrant + Ollama in self-hosted AI tutorials
  • MIT-licensed core gives clean commercial use for agencies + product teams

Tips & operations

  • Put Flowise behind a CDN when you embed widgets — public traffic hits your origin every page-load otherwise
  • Switch to Postgres for multi-instanceDATABASE_TYPE=postgres; default SQLite breaks under concurrent writes
  • Rate-limit API keys — a public widget without per-key limits can run up your OpenAI bill in hours
  • Rotate keys regularly — generate distinct API keys per consumer (one per embed location)
  • Test in dev with cheap LLM — wire Ollama local for prototyping, swap to GPT-4 only at production deploy
  • Persist /root/.flowise — flows + credentials live here; mount on a volume from day one

What we ship in BluixApps

  • Docker compose: Flowise + Postgres for flow persistence
  • Pinned flowiseai/flowise:2.2.4, monthly upstream tracking
  • Admin user with random password on first boot, surfaced in install report
  • Pre-configured to detect Ollama/Open WebUI on same VPS for zero-config LLM hookup
  • Vector store nodes pre-installed for Qdrant / Chroma when those apps also deployed
  • SSL via Let's Encrypt; embeddable widget URL points to HTTPS hostname
  • Backup hook covers Postgres + flow JSON exports
