Google AI refers to Google's family of proprietary AI models (like Gemini) and tools, accessed through Google's APIs and hosted products. The models are closed-weight, and applications built against them run through Google's hosted infrastructure and pricing.
Dify is worth a look if what you need is an open-source layer for building LLM applications — including ones that call Google's models via API — with visual workflows, RAG, and agent tooling you can self-host.
FAQ
Is there a free, open-source alternative to Google AI's platform tooling?
Dify is open source (Apache-2.0 with additional conditions) and self-hostable, though it's an application-building layer that can still connect to Google's models via API rather than a replacement for the models themselves.
What's the best open-source alternative to Google AI's app-building tools?
Dify is the strongest pick if you want a self-hosted platform for building LLM apps, agents, and RAG pipelines on top of Google's or other providers' models.
