What PeerDB does
PeerDB is a Postgres-native change data capture (CDC) and data replication platform founded in 2023 by Sai Srirampur (CEO) and Kaushik Iska (CTO). The software uses PostgreSQL logical decoding and replication slots to stream row-level changes from Postgres databases to analytical warehouses (Snowflake, BigQuery, ClickHouse), message brokers (Kafka, Redpanda, Google PubSub, Azure Event Hubs), Elasticsearch, and object stores (S3, GCS). Differentiated technical components include CTID-partitioned parallel initial loads, Avro+zstd in-transit compression, always-consumed replication slots that prevent WAL accumulation, schema-change auto-propagation, and Lua-scripted row transformations for PII masking and format conversion.
The product distributes through two channels: a free AGPL-3.0 open-source self-managed deployment and a managed cloud service, PeerDB Cloud, priced on vCPUs rather than data volume ($250–$4,000 per month). Pre-acquisition customers included Flatiron Health, Expedock, Vueling, SpotOn, Harmonic AI, Fiber AI, Findigs, and Supernova, spanning healthcare, supply chain, aviation, AI, and SaaS verticals. PeerDB was a Y Combinator S23 graduate and raised a $3.6M seed round led by 8VC in April 2024, bringing total funding to approximately $4.1M.
Following the July 2024 acquisition by ClickHouse, PeerDB's technology now powers the native Postgres CDC connector inside ClickHouse Cloud's ClickPipes integration engine. ClickHouse Cloud is the primary commercial distribution channel for the underlying PeerDB technology, and PeerDB Cloud now exclusively targets ClickHouse Cloud deployments.

PeerDB product offering
Product offeringCore offering
PeerDB is a Postgres-native replication platform that streams data from PostgreSQL databases to data warehouses (ClickHouse Cloud, Snowflake, BigQuery), message queues (Kafka, Redpanda, Google PubSub, Azure Event Hubs), and storage (S3, GCS, Elasticsearch) via change data capture (CDC). It is offered as a free open-source self-managed deployment (AGPL-3.0) and as a fully managed cloud service (PeerDB Cloud). Post-acquisition by ClickHouse in July 2024, its technology powers the native Postgres CDC connector inside ClickHouse Cloud's ClickPipes integration engine.
Product overview
PeerDB is a specialized Postgres replication platform offering both open-source and cloud-managed products. The core product, PeerDB Open Source (AGPL-3.0), provides CDC, streaming query, and query layer replication to data warehouses (ClickHouse, Snowflake, BigQuery) and queues (Kafka, Redpanda, PubSub, Event Hubs). PeerDB Cloud is the fully managed SaaS offering with enterprise features (HA, autoscaling, dedicated support). PeerDB Streams extends CDC capabilities to message brokers with Lua-based transformations. The SQL Interface enables Postgres-style ETL management. After acquisition by ClickHouse in July 2024, PeerDB technology powers ClickHouse's native ClickPipes Postgres CDC connector.

PeerDB competitors and assessment
Company assessmentEmerging players
- Hightouch: Reverse ETL platform focused on syncing data from warehouses back into operational systems. While not a direct CDC competitor, Hightouch is part of the same modern data integration ecosystem and competes for the same data team budget.
Broad incumbents
- Matillion: Cloud-native ELT platform with Postgres source support and deep Snowflake/BigQuery/Databricks integration. Overlaps with PeerDB's replication use cases but offers a broader transformation and orchestration layer.
- Hevo Data: No-code data pipeline platform with Postgres CDC support and pre-built integrations to Snowflake, BigQuery, and others. Competes in the same ELT/CDC market with a focus on ease of use rather than raw performance.
- Striim: Enterprise streaming data integration platform with CDC, real-time ETL, and SQL-based stream processing. Competes in the same Postgres-to-warehouse and queue replication space but with a broader, enterprise-focused portfolio.
- Confluent: Commercial Kafka platform with CDC connectors (including via Debezium) for streaming database changes. Overlaps with PeerDB Streams for Postgres-to-Kafka replication but operates as a much broader data streaming infrastructure vendor.
Direct peers
- Airbyte: Open-source ELT platform with extensive connector catalog including Postgres sources. PeerDB benchmarks itself at 10x faster than Airbyte on Postgres CDC to BigQuery and Snowflake; both companies compete in the open-source data integration space.
- Debezium: Open-source distributed platform for change data capture built on top of Kafka Connect. Debezium is the canonical open-source Postgres CDC alternative that PeerDB differentiates against with performance optimizations and managed delivery.
- Fivetran: Market-leading automated ELT/CDC platform with broad multi-source support including Postgres. PeerDB explicitly benchmarks against Fivetran on Postgres CDC cost and latency, and multiple PeerDB customers (e.g., Harmonic AI, Findigs) displaced Fivetran.
- Estuary Flow: Real-time data movement platform offering CDC and streaming ETL between operational databases (including Postgres) and warehouses/queues. Comparable to PeerDB in Postgres-to-warehouse replication with a focus on low-latency streaming.
- Arcion: CDC and replication platform with Postgres support, originally focused on zero-downtime database migrations. Offers comparable change data capture capabilities to warehouses like Snowflake and BigQuery (acquired by Databricks in 2023).
