“I want to build an AI SaaS”

One key for every model — swap between free and frontier without code changes.

Drop in for latency-sensitive calls; the free tier is genuinely usable.

Ingest and query your own data — the retrieval layer that grounds answers.

Store embeddings in-process to start; no separate service to run.

Give users persistent, personalized agent memory across sessions.

Drop-in sign-in and user management so you skip building auth.

Postgres, storage, and realtime with a generous free tier.

Push the backend and databases live without touching DevOps.
