Appendable – Index JSONL data and query via CDN
Hi HN! A friend and I were inspired by projects like https://github.com/sql-js/sql.js and the idea of querying files served over CDN with HTTP range requests. We started thinking: what would a database that was specifically designed for this type of use case look like? So we started building one, and we landed on a functional prototype that we're pretty proud of! With our prototype, Appendable, we're able to serve and query large (GB+) datasets by hosting them on a static file host like Amazon S3 or Cloudflare R2 without running a separate server and worrying about things…
Appendable – Index JSONL data and query via CDN launched on March 5, 2024 with 8 votes, #1,754 of 4,270 launches that month and more than 75% of that year's launches. The site was still online in September 2026, 2 years on.
What it does
Appendable is querying the JSONL and index files that GitHub pages hosts directly . There is no server involved here! Keep in mind that while the query syntax supports a lot of different operations, Appendable doesn't support composite indexes yet. Therefore, only one field at a time can be filtered on and that field must be used forfrom kevmo314.github.io

SQLite Plugin for Jekyll2024 · github.com · ▲227I love Jekyll, especially the Datafiles[0] feature, which lets you use CSV/JSON/YAML files and iterate through them. Mixed with the Jekyll Data Pages generator[1], which lets you create a page for every row in your dataset, it is a very powerful combination. However, Liquid is a terrible language for data-mangling, and simple filtering/sorting/merging can become very annoying. So I wrote a Jekyll SQLite plugin that lets you use the same data interface in Jekyll/Liquid, but backed by a SQLite file(s). It gives you the simplicity of the Baked Data pattern[2], and the…

TextQuery – Query CSV, JSON, XLSX Files with SQL2025 · textquery.app · ▲163Hiya 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…

Talanoa▲346Hi 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…
