Firebolt Core – #1 in ClickBench – Free Scale-Out Analytical SQL Engine
Hi HN, there’s a distinct lack of modern self-hosted scale-out query engines. A lot of the innovation in the last 10 years has been in SaaS-only systems. That’s also been true for Firebolt until now. We’re now taking the radical step of offering our query engine as a Docker image that’s free for commercial use without any real restrictions on what you can use it for (basically everything except competing with our SaaS offering). There are helm charts and docker compose files in the repo as well to help you get started. The focus of Firebolt is on low-latency, high-concurrency analytics like…

In the maker’s words, at launch
Hi HN, there’s a distinct lack of modern self-hosted scale-out query engines. A lot of the innovation in the last 10 years has been in SaaS-only systems. That’s also been true for Firebolt until now. We’re now taking the radical step of offering our query engine as a Docker image that’s free for commercial use without any real restrictions on what you can use it for (basically everything except competing with our SaaS offering). There are helm charts and docker compose files in the repo as well to help you get started. The focus of Firebolt is on low-latency, high-concurrency analytics like you might have them in user-facing workloads (dashboards, data-heavy apps, ...). To show just how fast it is, we submitted Core to ClickBench and instantly took the top spot: https://benchmark.clickhouse.com/. But Firebolt isn’t just a query accelerator, it can also handle scale-out ETL/ELT and all the other things you might want to use a data warehouse for. I’ve been working on Core for the last few months, and moshap (our CTO), wagjamin (VP Eng) and I are here for your questions. Mosha and Benjamin have written about our motivations to offer Core on the company blog: https://www.firebolt.io/blog/introducing-firebolt-core

- DRDuckDB + React = SQLRooms Framework for Analytics Apps Without Backend2025 · sqlrooms.org · ▲9
We’ve built SQLRooms, an open-source framework for creating single-node data analytics apps powered by DuckDB. It lets you build fully client-side, data-centric apps using React and DuckDB running in the browser (via WebAssembly) or in Electron. No server or backend is required — apps can work offline, preserve data privacy, and run queries on large datasets with sub-second performance. Features: - Query large datasets in browser with DuckDB (WASM) - Modular design for building composable data UIs (query editors, dashboards, notebooks, etc.) - Data privacy-preserving AI assistant that can…

Hey HN! Pilots everywhere are required to keep a logbook of all their flying hours, aircraft, airports, and so on. Since I track everything digitally (some people still just use paper logbooks!), I put together some data visualizations and a few 3D globes to show my flying history. This globe is probably my favourite so far: https://jameshard.ing/pilot/globes/all If you’ve got ideas for other graphs or ways to show this kind of data, I’d love to hear them!

I was the main contributor to workout.lol, an open-source fitness app to easily build a workout routine. The project had traction (1.4k GitHub stars, 95 forks, ~20K visits/month), but was eventually sold due to video licensing hurdles. The new owner stopped maintaining it, and the repo went abandoned. Over the next 9 months, I sent 15 emails to try to save it : no replies. Feature requests & issues were ignored. The community was left with a "broken" tool let's say. I couldn't just let it die So I built the new version from scratch with the same open-source spirit, but a better…
