BemiDB – Postgres read replica optimized for analytics

In plain words

BemiDB is a Postgres read replica optimized for analytics workloads. It allows teams to run large-scale data scans and aggregations without the complexity of separate OLAP systems or the performance trade-offs of adding indexes to production databases. The tool is designed for growing startups and engineering teams that want to keep their analytics stack simple while scaling their Postgres infrastructure.

Open-source Snowflake & Fivetran alternative, with Postgres compatibility. - BemiHQ/BemiDB

In the maker’s words, at launch

Hi HN! We're Evgeny and Arjun, and we’re building a better way to do analytics with Postgres. We love Postgres for its simplicity, power, and rich ecosystem. But engineers have to still get bogged down with heavyweight and expensive OLAP systems when connecting an analytics data stack. Postgres is amazing at OLTP…

  BemiDB – Open-source data warehouse with zero-ETL2025 · bemidb.com · ▲13

  Hi HN! We're Evgeny and Arjun, and we’re building a simpler way for startups to do data analytics. Since open-sourcing our Postgres read replica optimized for analytics (https://github.com/BemiHQ/BemiDB), we started hearing a familiar story. Teams would connect Postgres, feel relieved that they didn’t have to wrangle complex ETL pipelines, but then hit a wall as soon as they wanted to join data from HubSpot, Stripe, etc. They’d do hacky things like use Airbyte to sync data to their Postgres, so that it’d then auto sync to their BemiDB analytical database. We want to…

  PostgreSQL performance and cost across 23 EC2 instance typesJul 2026 · postgres.saneengineer.com · ▲97

  Hey! I'm Andrei. I got frustrated by how people tend to build overcomplicated backend systems, being "motivated" by big tech case studies and popular books. So, I started exploring lean architecture, and building my digital garden of ideas, approaches and data that align with this direction. Here I want to present one of the tools – Sizing tool for PostgreSQL. I've benchmarked PostgreSQL on different EC2 instances and disks, with different initial data sets to see performance that these instances can give you. And I've built a tool to visualize this data, which I welcome you to explore. So,…

  Hydra 1.0 – open-source column-oriented Postgres2023 · hydra-so.notion.site · ▲269

  hi hn, hydra ceo here hydra is an open source, column-oriented postgres. you can set up remarkably fast aggregates on your project in minutes to query billions of rows instantly. postgres is great, but aggregates can take minutes to hours to return results on large data sets. long-running analytical queries hog database resources and degrade performance. use hydra to run much faster analytics on postgres without making code changes. data is automatically loaded into columnar format and compressed. connect to hydra with your preferred postgres client (psql, dbeaver, etc). following 4 months…

  Lovable▲1,477

  Hey HN! Previous CERN physicist turned hacker here. We've developed a way to make AI coding actually work by systematically identifying and fixing places where LLMs typically fail in full-stack development. Today we're launching as Lovable (previously gptengineer.app) since it's such a big change. The problem? AI writing code typically make small mistakes and then get stuck. Those who tried know the frustration. We fixed most of this by mapping out where LLMs fail in full-stack dev and engineering around those pitfalls with prompt chains. Thanks to this, in all comparisons I found with: v0,…

  I wasn't quite sure if this qualified as "Show HN" given you can't really download it and try it out. However, dang said[0]: > If it's hardware or something that's not so easy to try out over the internet, find a different way to show how it actually works—a video, for example, or a detailed post with photos. Hopefully I did that? Additionally, I've put code and a detailed guide for the netboot computer management setup on GitHub: https://github.com/kentonv/lanparty Anyway, if this shouldn't have been Show HN, I apologize!
