Lovable AI Gateway

Managed LLM access from every Lovable app.

The AI Gateway gives Lovable apps a single, billed-by-Lovable endpoint for chat completions, image generation, embeddings, TTS and STT — without wiring up an OpenAI or Anthropic account. Perfect for prototypes and AI-native features that would otherwise stall on key management.

Tutorials

Add a streaming chat feature to your app

The reference pattern for a production chat surface on top of Gateway.

  1. Create an edge function that calls the AI Gateway with streaming enabled.
  2. Wire the frontend to fetch with ReadableStream and render tokens as they arrive.
  3. Persist final assistant messages to Postgres, not partial streams.
  4. Add rate-limits per user via a Cloud function.
  5. Set a workspace credit cap so runaway loops can't drain your balance.
FAQs
Do I need my own OpenAI key?+

No — the Gateway handles model access and billing. Bring your own key only if you want to.
