   Duck-UI – Browser-Based SQL IDE for DuckDB▲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…

   Open-source, browser-local data exploration using DuckDB-WASM and PRQL▲227

   Hey HN! We’ve built Pretzel, an open-source data exploration and visualization tool that runs fully in the browser and can handle large files (200 MB CSV on my 8gb MacBook air is snappy). It’s also reactive - so if, for example, you change a filter, all the data transform blocks after it re-evaluate automatically. You can try it here: https://pretzelai.github.io/ (static hosted webpage) or see a demo video here: https://www.youtube.com/watch?v=73wNEun_L7w You can play with the demo CSV that’s pre-loaded (GitHub data of text-editor adjacent projects) or upload…

   Use Claude Code to Query 600 GB Indexes over Hacker News, ArXiv, etc.▲397

   Paste in my prompt to Claude Code with an embedded API key for accessing my public readonly SQL+vector database, and you have a state-of-the-art research tool over Hacker News, arXiv, LessWrong, and dozens of other high-quality public commons sites. Claude whips up the monster SQL queries that safely run on my machine, to answer your most nuanced questions. There's also an Alerts functionality, where you can just ask Claude to submit a SQL query as an alert, and you'll be emailed when the ultra nuanced criteria is met (and the output changes). Like I want to know when somebody posts about…

   OpenSheet▲86

   Hi folks. I've been doing some experiments on how LLMs could get more handy in the day to day of working with files (CSV, Parquet, etc). Earlier last year, I built https://datakit.page and evolved it over and over into an all in-browser experience with help of duckdb-wasm. Got loads of feedbacks and I think it turned into a good shape with being an adhoc local data studio, but I kept hearing two main things/issues: Why can't the AI also change cells in the file we give to it? Why can't we modify this grid ourselves? So besides the whole READ and text-to-SQL flows, what seemed…

    TextQuery – Query CSV, JSON, XLSX Files with SQL▲163

    Hiya HN! TextQuery is my sabbatical project that I have been working on for the past six months. It was born out of a personal pain point. Anytime I wanted to analyze raw CSV data, I had to create a schema first before I could import it for querying. And to create charts, I had to use yet another tool. I also disliked how bad charts from popular tools like Excel, Google Sheets looked like. I wanted an easier way to do this and TextQuery was my solution: an all-in-one tool to query CSV files using SQL and create beautiful visualizations as well. Currently, it's a macOS app and focused on CSV…

    Turbolite – a SQLite VFS serving sub-250ms cold JOIN queries from S3▲185

    I built a SQLite VFS in Rust that serves cold queries directly from S3 with sub-second performance, and often much faster. It’s called turbolite. It is experimental, buggy, and may corrupt data. I would not trust it with anything important yet. I wanted to explore whether object storage has gotten fast enough to support embedded databases over cloud storage. Filesystems reward tiny random reads and in-place mutation. S3 rewards fewer requests, bigger transfers, immutable objects, and aggressively parallel operations where bandwidth is often the real constraint. This was explicitly inspired…

    Replicate App-Embedded DuckDBs into PostgreSQL with SyncLite OSS▲73

    Hi HN, We have been building SyncLite, an open-source platform to simplify offline-first application development. If your application uses SQLite or DuckDB, SyncLite lets it continue using the local database as usual while synchronization happens in the background. For SQL-based applications, SyncLite records transactions into transactionally consistent .sqlog files using SQLite as an open replication format. A background consolidator replays those transactions, derives row-level CDC and schema changes, and applies them transactionally to destination databases like PostgreSQL. The same…

    SQLite query inside a Bash function▲134

    Part of the workflow for building my website is the generation of a table in tab-separated column format (.tsv). The source data is found in four other .tsv files. I use an SQLite query to perform a 4-way join and write out the new table. For convenience, I wrote a script that encapsulates the query inside a Bash function. The example below illustrates this technique. repertoire() { pushd $CMM_SOURCES&#x2F;_data sqlite3 <<EOS .headers on .mode tabs .import category.tsv category .import composition.tsv composition .import concert.tsv concert .import program.tsv program .once repertoire.tsv…
