Products that do what Qduck – DuckDB client API for KDB/Q does

Open source library for allowing KDB users to interact with DuckDB. The main motivation was to be able to query open data formats on s3 buckets without having to rely on python/pykx. Great for adhoc research when you want to join new data with existing data stored in KDB.

    Dear HN, I am Riwaj, the cofounder of dstack.ai (https://github.com/dstackai). A few months ago, we built an online service that allows users to publish data visualizations from Python or R. The idea was to build a tool that did not require additional programming or front-end development for publishing data visualizations. Such a code can be invoked from either Jupyter notebook, RMarkdown, Python, or R scripts. Once the data is pushed, it can be accessed via a browser. Open-sourcing dstack: During our customer discovery phase, we realized that dstack.ai should integrate a lot…

    Hi everyone, I'm a PhD student in databases at CMU. Over the past few months, I've been interning at Columnar and building a community extension for DuckDB that lets you query Snowflake, Databricks, BigQuery, PostgreSQL, MySQL, and any other system with an ADBC (Arrow Database Connectivity) driver. The extension supports querying ADBC databases directly through a read_adbc table function. It also supports using ATTACH to connect to an ADBC database and then running SELECT, INSERT, COPY, and CTAS statements as if the database were local to DuckDB. You can install it from DuckDB by running:…

    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…

    Hi, A few months ago, I shared a tool I built for personal use to easily trace HTTP client requests in any Python app. It links requests to the corresponding Python code and comes with a nice UI. By easily, I mean: no external dependencies, no setup, no superuser rights, and no code modifications — just do "pip install httpdbg" and then launch your code using the "pyhttpdbg" command. That’s it. I received a lot of positive feedback — not just here, but also on social media, in podcasts, and beyond. So, thank you! Since I last introduced httpdbg, I’ve made many improvements — based on both my…

    I built this library because I kept rewriting the same fetch wrapper for every project. Each time, I needed the same core features: - Make fetch throw errors to integrate smoothly with libraries like TanStack Query - Add sensible defaults to the Fetch API, like a base URL and authentication headers - Validate responses for type safety when OpenAPI isn’t an option I also wanted the library to feel exactly like using fetch — no new API to learn, and no extra friction for my teammates. While there are other great options out there, I found many were either too rigid or too bulky. Doesn’t it…

    Hi there HN! I wanted to show you a weekend project I put together. Pingquick (https://www.pingquick.dev/) is a way to create APIs from your python functions. Just write/paste the function in, and it'll give you an endpoint to POST to. I made Pingquick because I just couldn't stand having to deal with deployment for some simple python functions. So, now I just put my code there and I can ping it as needed without needing to worry about any setup. Any and all feedback is very much welcome! Ian

    Hey hacker news! I built Melchi, an open-source tool that handles Snowflake to DuckDB replication with proper CDC support. I'd love your feedback on the approach and potential use cases. *Why I built it:* When I worked at Redshift I saw two common scenarios that were painfully difficult to solve: Teams needed to query and join data from other organizations' Snowflake instances with their own data stored in different warehouse types, or they wanted to experiment with different warehouse technologies but the overhead of building and maintaining data pipelines was too high. With DuckDB's…
