When to use Flowise
| Stage | Tool |
|---|---|
| Prove RAG on sample docs | Flowise |
| Internal team chatbot v1 | Dify or Flowise |
| Customer embed + API keys | Dify |
| Zendesk to Slack automation | n8n |
Quick start
npx flowise start
# Open http://localhost:3000
Add: Document Loader → Text Splitter → Embeddings → Vector Store → Chat Model → Chatflow.
Swap embedding models by reconnecting one node — the core Flowise workflow.
2.0 agent templates
Templates ship for:
- RAG Q&A — upload PDFs, test citations
- Research — search tool + synthesis
- Support triage — classify + draft pattern
Customize nodes after template load — faster than blank canvas.
Migration to Dify
When stakeholders approve the prototype:
- Export chunk size, embed model, and top-k settings
- Rebuild knowledge base in Dify
- Add API keys, SSO, embed widget
- Retire Flowise flow or keep for R&D
