Database for Astro

Among 23 makers' products we track that are built with Astro, here's what they chose for database — each counted from a live-product source.

Where the data lives: a whole backend platform (database, auth and storage in one project), a managed database you reach from your own code, or the raw engine on your own server. Postgres is the default unless you have a reason to pick otherwise; analytics and graph databases sit next to it for workloads it handles poorly, not instead of it. How your code talks to it is its own decision (Database Access & ORMs).

What makers on Astro chose

Counts are live products with a source, not market share; a product using two options counts in both.

SupabaseBackend platform

llms.txt MCP CLIIn Bolt, Lovable, v0

Best forPostgres plus auth, storage and realtime in one project.

Trade-offAuth, storage and database in one vendor makes leaving harder later, and free projects pause after a week without activity.

llms.txt MCPIn Lovable

Best forFast aggregate queries over billions of rows of events, logs or metrics, self-hosted or on ClickHouse Cloud.

NeonManaged database

llms.txt MCP CLIIn v0

Best forServerless Postgres that scales to zero, with a branch per preview deploy.
