Open-Source Data Warehouse.
Built for Postgres

BemiDB relies on the same open-source technologies used by Netflix, Apple, and Airbnb—packaged for simple self-hosting. It connects directly to your Postgres database, syncing data into compressed columnar Iceberg tables stored in object storage. DuckDB powers the embedded query engine for fast analytics on large datasets. And because it uses the Postgres wire and query protocol, it works with any existing Postgres-compatible tool right out of the box.

It means you don't need separate processes to extract, transform, or load data for analytics. BemiDB automatically syncs data from Postgres and stores it in a query-ready columnar format—removing the overhead of building and maintaining complex pipelines.

No. The sync process is lightweight and won't add any noticeable load to your transactional database. Once data is synced, BemiDB handles analytics queries separately, reducing strain on your primary Postgres.

Just run a single binary. Point it to your Postgres instance, and BemiDB takes care of the rest—syncing schemas and data automatically. No extra configuration or manual steps. Contact us for best practices and how to deploy.

BemiDB natively supports storing data on a local disk or in your own S3 bucket. This means you have full control of where the data resides, ensuring no vendor lock-in and complete ownership.

Yes, BemiDB is an open-source project with an AGPL-3.0 license approved by the Open Source Initiative (OSI). You can use it for free, modify it, and contribute to the project. We believe that open-source is the best way to build software.
