Citus 11.3 is out! Now with tenant statistics. Read all about it in Marco's 11.3 blog post. 💥
Citus gives you all the greatness of Postgres, plus the superpower of distributed tables. 100% open source. Now with tenant monitoring for SaaS.
Scale Postgres by distributing data & queries. You can start with a single Citus node, then add nodes & rebalance shards when you need to grow.
Speed up queries by 20x to 300x (or more) through parallelism, keeping more data in memory, higher I/O bandwidth, and columnar compression.
Citus is an extension (not a fork) to the latest Postgres versions, so you can use your familiar SQL toolset & leverage your Postgres expertise.
Reduce your infrastructure headaches by using a single database for both your transactional and analytical workloads.
Download and use Citus open source for free. You can manage Citus yourself, embrace open source, and help us improve Citus via GitHub.
Focus on your application & forget about your database. Run your app on Citus in the cloud with Azure Cosmos DB for PostgreSQL.
The Citus database gives you the superpower of distributed tables. Because Citus is an open source extension to Postgres, you can leverage the Postgres features, tooling, and ecosystem you love. And in Citus 11, you can now query from any node—plus we’ve open sourced the few remaining Citus Enterprise features. With Citus, you can scale from a single node to a distributed cluster, giving you all the greatness of Postgres—at any scale.CAPABILITIES TABLE
SaaS apps often have a natural dimension on which to distribute data across nodes—dimensions such as tenant, customer, or account_id. Which means SaaS apps have a data model that is a good fit for a distributed database like Citus: just shard by tenant_id.
Customer-facing real-time analytics dashboards need to deliver sub-second query responses to 1000s of concurrent users, while simultaneously ingesting fresh data and enabling users to query the fresh data in real time, too.
By scaling out Postgres across multiple nodes, Citus gives your analytics dashboards the compute, memory, and performance they need to process billions of events in real time.
Whether your app works with financial data, website analytics, IOT data, ad tech, or any other type of monitoring data—time series workloads often need to grow beyond the memory, compute, and disk of a single node.
Citus gives you parallelism, a distributed architecture, and columnar compression to deal with large data volumes—and can be combined with PostgreSQL’s time partitioning to optimize your timeseries queries.

Customers ask how many weeks they have to wait for results, but with Citus it takes us roughly three minutes. The difference is so striking compared to our competitors, customers usually struggle to understand how we can do it.Rasty Turek, Founder and CEO, Pex
The speed change of Citus is a game changer. With Citus, we can make indexes in minutes that used to take hours.Jesse Willett, Former Principal Architect, Copper
We expected a database migration to be a huge code change, requiring a lot of rewrites. But Citus has a Django multi-tenant library, which minimized the refactoring to migrate our application. Except for rewriting a few lines of our app, we ended up using pretty much the same code.Shashank Kumar, Founder, PushOwl
Citus handles our complex ingest and delete operations seamlessly—and that’s with a workflow that creates five to ten billion new rows of data per day. The way in which Citus shards and distributes data across multiple nodes has given us the parallelization we need.Sylvain Friquet, Former Software Engineer, Algolia
Thanks to Citus, we’re powering a product that is really kind of magical for a lot of customers. The speed and performance of our database make it possible for them to immediately perform truly advanced analytics on any user activities they want to explore.Dan Robinson, CTO, Heap
We provisioned a new database using the Citus console, ran our migrations, copied over our data from Heroku, and we were up and running on Citus in just a few minutes. And the technical benefits were instant. We saw queries that were once takingJonathan Denney, CTO and Co-Founder, ConvertFlow
15-30+seconds reduced to less than 500 ms.
With Citus, you extend Postgres with superpowers like distributed tables, distributed SQL query engine, columnar, & more.
You can also spin up a Citus cluster in the cloud on Azure with Azure Cosmos DB for PostgreSQL.
