Among 53 makers' products we track that are built with React, 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).
Counts are live products with a source, not market share; a product using two options counts in both.

Best forDocument-shaped data and teams already fluent in Mongo.
Trade-offNo joins or schema by default, so relational data and migrations take discipline you'd get for free in Postgres.

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.

Best forFast aggregate queries over billions of rows of events, logs or metrics, self-hosted or on ClickHouse Cloud.
Trade-offBuilt for bulk inserts and scans, not frequent row updates or transactions; runs next to your main database, not instead of it.

Best forRealtime, collaborative apps written entirely in TypeScript.
Trade-offIts own data model and query API rather than SQL.

Best forPHP, Laravel, WordPress and Rails stacks, and teams that already know MySQL well.
Trade-offFewer extensions and advanced types than Postgres, so most new tooling (vectors, JSON-heavy work) targets Postgres first.

Best forAnalytical SQL inside your app or script over local or S3-hosted CSV and Parquet files, with no server to run.
Trade-offAn embedded library, so it doesn't serve many concurrent writers like a database server does.

Best forData that is mostly relationships — social graphs, recommendations, knowledge graphs — queried with Cypher.
Trade-offA second database and query language to learn and run; managed AuraDB is priced by memory.
