Scale out without sacrifice

You shouldn’t have to re-architect your app when you hit the ceiling on single-node Postgres. Because sharding at the application layer steals time & resources from your core business. Not to mention the maintenance. There is a better way. At Citus, we make it simple to shard Postgres.

Query faster than any one server can

By parallelizing your SQL queries across multiple nodes, Citus can deliver sub-second performance. Even with real-time data ingest across billions of rows of data, with boatloads of concurrent queries. And adding nodes to increase parallelism is simple.
