Blazing fast results

No more compromising between flexibility and speed. Materialize delivers SQL exploration for streaming events and real-time data.

Full SQL Development

No "inspired by SQL" capabilities or half-broken query languages. Materialize is wire compatible with PostgreSQL.

Correct, not just consistent

No more ‘eventual consistency’. Materialize emphasizes the correct answer in real-time - without interference from late-arriving data.

A Platform for SQL on Streaming Data

Materialize lets you ask questions about your data, and then get low-latency, correct answers, even as the underlying data changes.

Why not just use your database’s built-in functionality to perform these same computations? Because your database often acts as if it’s never been asked that question before, which means it can take a long time to come up with an answer, each time you pose the query.

Materialize instead keeps the results of the queries and incrementally updates them as new data comes in. So, rather than recalculating the answer each time it’s asked, Materialize continually updates the answer and gives you the answer’s current state from memory – even in the presence of complex joins and arbitrary inserts, updates, or deletes in the input streams.

Sign up for Early Access to Materialize Cloud

We’d love to learn more about how developers and data engineers can use Materialize. If you’d like to learn more about testing Materialize – or if you’d like to be included in our early access program for our cloud product – please complete the form below, and someone from our team will be in touch promptly.


Standard ANSI SQL

Materialize provides a single element in the most common programming language. Lower the burden on your data platform team and reuse skills from traditional SQL queries and applications.

We support the TPC-H benchmark – a standard built for industry-wide relevance, large data volumes, and high query complexity – with incremental updates.

Complex Joins on
Streaming Data

Many streaming solutions require the denormalization of data in order to maintain low latency – thereby prohibiting any kind of data enrichment like joins.

By contrast, Materialize offers joins in a SQL interface – including complicated multiple-way (e.g. 6-way, 12-way) joins across disparate data sources.

Up and Running in 5 Minutes

Materialize is a source-available product and can be installed with a single command line. Rather than spend weeks building microservices, teams can build applications with Materialize in a matter of hours.

Unlike similar solutions that require pre-processing of data, Materialize connects to data as it exists today – including streaming sources like Kafka, to databases as a read-replica, or from files.

Try Materialize for Yourself Now

Building applications for streaming data can be as simple as writing a few lines of SQL. Our Quick Start guide can take you through the process of installing Materialize, exploring our API, creating a stream, and get you up and building quickly.


Connects directly to event stream processors

Materialize connects directly to your streaming infrastructure, ingesting streams of data from event stream processors like Kafka. Or connect us directly to your database as a read replica.

Simplify your streaming data architecture. With Materialize, there is no pre-processing of data required to make the system work.

Combine and analyze real-time and historical data

Want to run queries against both real-time and historical data? Simply connect Materialize to a storage system like Amazon S3 and union both sources together for a full picture of your data.

The potential for these kinds of enriched streams is massive, and we’re excited to see what our customers can do.

Install Materialize

Presents as Postgres downstream

Materialize is wire compatible with PostgreSQL, presenting to downstream tools like any Postgres database, simplifying the development of custom applications and streamlining the process of connecting existing data analysis tools.

Even non-technical users can unlock the most complex real-time queries just using standard BI tooling.
