Dify — free open-source OpenAI alternative
157,730 GitHub stars
Build Agentic workflows, RAG pipelines, with rich AI model and tool support on one collaborative workspace. Deploy on cloud, VPC, or self-hosted, so teams move
Replaces: OpenAI + Chatbase + Voiceflow — the paid alternative. Dify does the same job and the licence is $0: you pay only for the server it runs on.
Why teams switch to Dify
- $0 licence. The paid tool charges per seat every month. Dify is free forever, including commercial use under its open-source licence.
- Your data stays yours. Dify is self-hosted — it runs on your own server, so no third party holds your records.
- Proven at scale. 157,730 GitHub stars and an active contributor base mean real companies run this in production, not just hobbyists.
Trade-off, honestly: open-source means you (or an IT person) install and maintain it. If nobody on your team can run a server, the paid alternative may still be the right call — that is what it is charging for.
