Database
Database tools are for storing and querying application data — the kind of work every indie hacker eventually hits and would rather not build from scratch. 7 tools are listed here, each picked and written up individually rather than pulled from an affiliate feed. CockroachDB is usually the first one people try: postgres-compatible distributed SQL that keeps writing when a whole region drops — overkill until it isn't. MongoDB Atlas takes a different angle — the managed way to run MongoDB when you actually need documents, not rows, and don't want to run the cluster yourself. And Neon is worth a look too: postgres that branches like Git and scales to zero, so preview environments stop costing you real money. Every listing below includes the actual tradeoff, not marketing copy, so you can pick based on what you're building instead of what ranks highest in a sponsored roundup elsewhere.

Vitess-grade MySQL scaling with schema branching, for when you'd rather not fear your next migration.
A hosted Postgres with auth, storage, and realtime already wired up — the default pick if you don't want to think about infra.
SQLite pushed to the edge and multiplied by thousands — built for per-tenant databases, not one big cluster.
Redis and vector storage billed per request instead of per idling server — built for functions that sleep most of the day.
