  500+ Free Online Tools In One Place – developers, designers, studentsNov 2025 · everytoolkit.com · ▲11

  I built EveryToolkit.com — a collection of 500+ free online tools across 24+ categories, all in one clean, fast, and ad-supported site. The goal is to make small, everyday utilities accessible from one place — no popups, no clutter. You’ll find: • Developer tools (JSON, JWT, regex, base64, etc.) • Text and writing tools (word counters, formatters, case converters) • Image & PDF tools (compress, convert, merge) • Finance, health, and SEO utilities • Calculators and converters for daily use I built this to solve my own frustration of having to Google for “that one tool” every time. Would love…

  Talanoa▲346

  Hi 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…

  22 GB of Hacker News in SQLite▲730

  Community, All the HN belong to you. This is an archive of hacker news that fits in your browser. When I made HN Made of Primes I realized I could probably do this offline sqlite/wasm thing with the whole GBs of archive. The whole dataset. So I tried it, and this is it. Have Hacker News on your device. Go to this repo (https://github.com/DOSAYGO-STUDIO/HackerBook): you can download it. Big Query -> ETL -> npx serve docs - that's it. 20 years of HN arguments and beauty, can be yours forever. So they'll never die. Ever. It's the unkillable static archive of HN and it's…
