Original

CockroachDB is a cloud-native distributed SQL database designed to build, scale, and manage modern, data-intensive applications.

What is CockroachDB?

CockroachDB is a distributed SQL database built on a transactional and strongly-consistent key-value store. It scales horizontally; survives disk, machine, rack, and even datacenter failures with minimal latency disruption and no manual intervention; supports strongly-consistent ACID transactions; and provides a familiar SQL API for structuring, manipulating, and querying data.

For more details, see our product overview, FAQ or architecture document.

Docs

For guidance on installation, development, deployment, and administration, see our User Documentation.

Starting with CockroachCloud

We can run CockroachDB for you, so you don't have to run your own cluster.

See our online documentation: Quickstart with CockroachCloud

Starting with CockroachDB

Install CockroachDB: using a pre-built executable or build it from source.
Start a local cluster and connect to it via the built-in SQL client.
Learn more about CockroachDB SQL.
Use a PostgreSQL-compatible driver or ORM to build an app with CockroachDB.
Explore core features, such as data replication, automatic rebalancing, and fault tolerance and recovery.

Client Drivers

CockroachDB supports the PostgreSQL wire protocol, so you can use any available PostgreSQL client drivers to connect from various languages.

For recommended drivers that we've tested, see Install Client Drivers.
For tutorials using these drivers, as well as supported ORMs, see Example Apps.
