Serverless SQLite
SQLite databases that run alongside Cloudflare Workers on the free Workers plan.
The catch: Only 100,000 row writes per day, which resets daily.
BaaS + hosting
Google's app backend: static hosting, auth and Firestore on the free Spark plan.
The catch: Cloud Functions, App Hosting and (for new projects) Cloud Storage need the pay-as-you-go Blaze plan.
Edge SQLite
Hosted SQLite (libSQL) with many small databases and edge replicas.
The catch: Only one day of point-in-time restore on the free plan.
Serverless Redis
Serverless Redis you call over HTTP, priced per request.
The catch: 500K commands a month runs out fast if you poll or cache every request.

The catch: 512 MB fills quickly, and there is a 100 ops/sec cap.
Serverless Postgres
Serverless Postgres with branching that scales to zero when unused.
The catch: Only 1 GB of storage per project.
