About this API

CockroachDB (Cockroach Labs) is a distributed SQL database founded 2015 (founding team from Google Spanner team). Tech core: open-source (BSL) implementation of Spanner's "globally distributed + strongly consistent" philosophy, plus Postgres wire protocol compatibility (your Postgres app changes connection string to use CockroachDB). Differentiators vs. single-node Postgres: (1) True horizontal scaling (adding nodes linearly increases capacity, unlike RDS big-single-machine limits); (2) Multi-region strong consistency (critical for finance, single transaction visible consistently in EU/US/Asia); (3) Auto-failover (node death triggers automatic failover). Cost is complexity — if you don't need globally distributed + strong consistency, simpler RDS suffices; config and ops cost exceeds RDS. Cloud is the managed version; serverless tier lets small projects experiment. Customers mainly banking, payments, global e-commerce — high-consistency-requirement scenarios.

What you can build

1Global user financial / payments apps (multi-region data consistency)
2Replace Spanner but need Postgres compatibility
3Mission-critical services (DB 5+ 9s availability)
4High-traffic SaaS horizontal scaling

Strengths & limitations

Strengths

Postgres-compatible (drivers / SQL work directly)
True horizontal scaling (unlike RDS single-machine limits)
Spanner-like strong consistency + global distribution
Serverless option available

Limitations

Complex / steep learning curve
Single-region apps simpler/cheaper on RDS / Aurora
Some Postgres features unsupported (extensions, specific types)

Example request

Generic template — replace <endpoint> with the real path from the docs.

curl https://www.cockroachlabs.com/<endpoint> \
  -H "Authorization: Bearer $API_KEY"
# Some providers use X-Api-Key instead — verify in the docs.

Getting started

Sign up at cockroachlabs.cloud and create cluster. Postgres-compatible connection: psql postgresql://user:pass@host:26257/db?sslmode=require

FAQ

When to use CockroachDB over Postgres?+

Need multi-region strong consistency + true horizontal scaling. Otherwise Postgres (RDS / Aurora) is simpler.
