Flowise is the rare tool that is both truly open source (Apache-2.0) and offers a real affiliate on its hosted tier. Self-hosters get the full product for free; teams that want it managed can use the cloud, and that is where the 20% recurring applies.

For building LLM apps and agents visually, it is the best-of-both-worlds pick, and the honest lead for any automation comparison on this site.

The good

  • Genuinely Apache-2.0 open source AND has a real affiliate on the cloud tier
  • Drag-and-drop LLM/agent flows
  • Self-host or use the hosted version

The catch

  • Cloud commission caps at 12 months
  • Younger than the incumbents
  • Complex flows still need engineering care

Pricing

Self-host free (Apache-2.0); Cloud tier is paid.

Alternatives to consider

  • Langflow A visual, MIT-licensed builder for LangChain-style agent flows.
  • n8n Source-available workflow automation with AI-agent nodes.
