What it does
GizmoSQL is an Arrow Flight SQL server with DuckDB or SQLite as back-end SQL database engines. With GizmoSQL, you can run DuckDB remotely and securely, with TLS and authentication. Run terabyte-scale analytics, outperforming legacy engines for 80% less cost!
GizmoSQL is an enterprise, terabyte-scale OLAP SQL engine powered by Apache Arrow Flight SQL and DuckDB. Ideal for LLM and AI agent workloads — a shared SQL server for multi-agent workflows. Process billions of rows in seconds for 90% less cost.
GizmoSQL runs standard SQL on open formats you control — query terabytes in seconds at up to 90% less than Snowflake or Databricks. Self-host it in your own cloud or on-premises (or let us run it fully managed). Your data and your keys never leave your infrastructure. Warehouse-grade analytics on infrastructure you control — measured, not promised. Flat per-vCPU pricing on hardware you choose — no credits, no DBUs, no per-byte scan charges. Costs stay fixed while your usage grows. The full TPC-H 1 TB benchmark in about 80 seconds on a single cloud VM — about $0.17 of compute per run. Arrow Flight SQL, JDBC, ADBC, and ODBC. Tableau, Power BI, dbt, DBeaver, and your notebooks keep working —…from gizmodata.com

- DUDuck-UI – Browser-Based SQL IDE for DuckDB2025 · demo.duckui.com · ▲213
I built Duck-UI, a web-based SQL editor that runs DuckDB entirely in your browser via WebAssembly. No backend required. The Problem: Every time I needed to query csv, parquet, or even to play with SQL, I had to either: (a) spin up a Jupyter notebook (b) use the CLI (c) upload to a hosted service. Friction at every step (TOO MUCH to load a csv or even to test some sql (study)... The Solution: DuckDB's WASM runtime lets us run SQL analysis client-side. Load CSV/JSON/Parquet files from disk or URL, write SQL, get results instantly. Data stays on your machine. What It Does: SQL editor…

Talanoa▲340Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
