Postgres Managed by ClickHouse Enters Public Beta, Free Until Metering Begins June 15

Overview

ClickHouse, the company behind the analytics database of the same name, has moved its managed transactional Postgres service from private preview into public beta. The service, named “Postgres managed by ClickHouse,” runs on local NVMe storage and integrates with ClickHouse through a native change-data-capture (CDC) pipeline. According to the ClickHouse blog, the service “remains free until usage metering begins on June 15, 2026.”

The public-beta transition was announced at Open House 2026, ClickHouse’s user conference, which the company opened on May 27, 2026 in San Francisco. The move marks an analytics-database vendor pushing directly into the transactional (OLTP) Postgres market occupied by AWS RDS, Aurora, Neon, and others.

What We Know

ClickHouse first announced the service as a private preview on January 22, 2026, describing it as “a fast, scalable and an enterprise-grade managed Postgres service natively integrated with ClickHouse, built for real-time and AI-driven applications.” The company says the service moved “from private preview to public beta” at the conference, per the Open House 2026 recap.

The architecture centers on local NVMe storage. ClickHouse states the storage is “physically colocated with compute, delivering orders of magnitude lower disk latency and higher IOPS than alternatives such as EBS-backed volumes,” according to the private-preview announcement. On that basis the company claims the service delivers “up to 10x faster transactional performance,” as described in the beta announcement.

Two integration features tie the Postgres service back to ClickHouse. The first is native CDC: ClickHouse says “a Postgres-native CDC pipeline streams inserts, updates, and deletes directly into ClickHouse with no intermediate infrastructure, handling both parallel initial snapshots and continuous replication,” per the Open House recap. The second is the pg_clickhouse extension, which the company says “enables users to query ClickHouse directly from Postgres” and “provides comprehensive query pushdown to ClickHouse for efficient query execution, including support for FILTERs, JOINs, SEMI-JOINs, aggregations, functions and more,” according to the private-preview post. Both “Native CDC via ClickPipes and the pg_clickhouse extension are included at no additional cost” during the beta, the beta announcement states.

On pricing, the beta announcement says the service is free until metering begins on June 15, that “during Beta, all plans include a 50% discount,” and that “every new account includes $300 in free credits.” The smallest configuration listed is “1 vCPU / 8 GB RAM / 59 GB NVMe” deployments “starting at approximately $32/month.”

The Benchmarks

ClickHouse published its own benchmark, PostgresBench, alongside the launch. The PostgresBench post describes it as a “reproducible benchmark” whose “full benchmark repository is open source” on GitHub, comparing “Postgres managed by ClickHouse,” “AWS RDS for PostgreSQL,” “AWS Aurora PostgreSQL,” “Neon,” and “Crunchy Bridge.” The benchmark uses pgbench with 256 clients, 16 threads, and 10-minute runs.

In ClickHouse’s own results at roughly 100 GB of data, its largest Postgres configuration recorded 28,668 transactions per second, against 8,133 for AWS RDS, 12,628 for AWS Aurora, 8,563 for Neon, and 14,790 for Crunchy Bridge, according to the PostgresBench post. Summarizing those numbers, ClickHouse says in early benchmarks the service “delivers over 5x more transactions per second than AWS RDS and 2.4x more than the next closest alternative,” per the Open House recap.

For the analytics side, ClickHouse claims “up to 100X faster analytics” when transactional data is synced into ClickHouse, and that “14 of 22 TPC-H queries are fully pushed down, delivering over 60x performance improvements compared to standard Postgres,” according to the private-preview post. At the conference the company reported that in “early TPC-H testing at scale factor 100, the full benchmark suite ran in 54.7 seconds on eight nodes, down from 117.6 seconds on a single node,” per the Open House recap.

Business Context

The Postgres beta lands as ClickHouse reports rapid commercial growth. At Open House 2026, the company said its “serverless cloud offering has crossed over $250 million in annual run-rate revenue” and that it had “added more than 1,000 net new customers since January,” bringing its total to 4,000, according to its conference announcement. “AI workloads demand the performance and cost efficiency ClickHouse was built for, and the last quarter has made that clearer than ever,” said Aaron Katz, CEO of ClickHouse, in the same announcement.

The launch puts ClickHouse in a market where it competes with established managed-Postgres providers and with vendors converging transactional and analytical systems. Databricks took a similar unified approach with Lakebase, its serverless PostgreSQL offering, as previously reported.

What We Don’t Know

All of the performance figures cited above are ClickHouse’s own benchmarks, run by the vendor. While ClickHouse says the PostgresBench repository is open source and reproducible, the results have not been independently verified by a third party. The TPS and TPC-H numbers reflect specific instance sizes, scale factors, and configurations chosen by ClickHouse, and real-world performance will vary with workload.

ClickHouse has not published a permanent post-beta price list; the $32/month starting figure and the 50% discount apply during the beta period, and the company says that “as we move toward General Availability, pricing and packaging may evolve.” It has not announced a general-availability date. How the service performs on production OLTP workloads at scale, and whether its NVMe-colocation model introduces durability or failover trade-offs relative to network-attached storage, remains to be seen as the public beta widens.
