Database for React

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).

What makers on React chose

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

FirebaseBackend platform

llms.txtIn Lovable

Best forMobile apps that need offline sync and client-side SDKs.

Trade-offA document store without SQL joins; hard to migrate off.

PostgreSQLRun it yourself

In Replit

Best forThe engine behind most of the hosted options above, run on your own server or container for full control and a flat cost.

Trade-offBackups, upgrades, failover and connection pooling are yours to set up and watch.

MongoDBManaged database

llms.txt

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.

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.

ClickHouseAnalytics (OLAP)

llms.txt MCPIn Lovable

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.

ConvexBackend platform

llms.txt CLI

Best forRealtime, collaborative apps written entirely in TypeScript.

Trade-offIts own data model and query API rather than SQL.

MySQLRun it yourself

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.

DuckDBAnalytics (OLAP)

llms.txt

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.

Neo4jGraph

llms.txt

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.
