24 alternatives to I vibecoded 177 tools for my own use (CalcBin)
Hey HN! I've been building random tools whenever I needed them over the past few months, and now I have 177 of them. Started because I was tired of sketchy converter sites with 10 ads, so I just... made my own. Some highlights for the dev crowd: Developer tools: - UUID Generator (v1/v4/v7, bulk generation): https://calcbin.com/tools/uuid-generator - JWT Generator & Decoder: https://calcbin.com/tools/jwt-generator - JSON Formatter/Validator: https://calcbin.com/tools/json-formatter - Cron Expression Generator (with…
CalcBin is a collection of 177 utility tools built ad-free for developers and general users. It includes developer-focused features like UUID generators, JWT and Base64 tools, JSON formatters, regex testers, cron… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

I figured I needed to work on my coding skills before building the next groundbreaking AI app, so I started working on this free tool site. Its basically just an aggregation of various commonly used calculators and unit convertors. Link: https://www.calcverse.live Tech Stack: Next, React, Typescript, shadcn UI, Tailwind CSS Would greatly appreciate your feedback on the UI/UX and accessibilty. I struggled the most with navigation. I've added a search box, a sidebar, breadcrumbs and pages with grids of cards leading to the respective calculator or unit convertor, but not sure if…

Hey there, I'm a solo dev behind KewlTools. So I'm one of those people who like to build their own tools/utilities whenever they a) want to get something done, or b) want to learn something. c) don't want to spend ages finding a utilty and going through walls of ads. I gradually built 66 tools, all free, fast, ad-free, and zero login. I (and my family/friends) use these daily, so thought some of you will find it useful! Any suggestions, improving current tools or adding new ones, please let me know.
