Dify
Open-source LLM app platform — visual workflow, RAG, agents, 100+ models.
Apache-2.0 platform with Prompt IDE, RAG pipelines, agent framework, and model management. Self-host with Docker or use cloud.dify.ai.
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.
