If I wanted to connect my app to a database (not hosted out of fly.io), then what are my options ?
- Only Postgres ?
- I can’t connect to a MySQL database ?
- What are the limitations of Postgres under the free resources tier ?
- If I choose sqlite3, where does it get stored ?
A good place to start is with the Databases & Storage guide. This includes Volumes (for sqlite3) and recommended storage providers (for Postgres, MySQL, and an S3 compatible object store).
The Fly App Pricing page provides information on Free Allowances.
