Open-source tools for devs who don't like ads
Hey HN, wanted to share a new collection of dev utilities that are ad-free, client-side (nothing leaves your device), with a command+k menu for fast search. github.com/jamdotdev/jam-dev-utilities Why? The sites we use every day for data conversion (e.g. PNG to data URI) are cluttered with ads, one of those mildly annoying things engineers deal with while writing code. This came up at a recent team dinner, and we got interested in creating nicer, modern, uncluttered versions of these tools. Since then, every time we needed a util, we added it to our stack. Lots more tools still to…
What it does
In the maker’s words, at launch
Hey HN, wanted to share a new collection of dev utilities that are ad-free, client-side (nothing leaves your device), with a command+k menu for fast search. github.com/jamdotdev/jam-dev-utilities Why? The sites we use every day for data conversion (e.g. PNG to data URI) are cluttered with ads, one of those mildly annoying things engineers deal with while writing code. This came up at a recent team dinner, and we got interested in creating nicer, modern, uncluttered versions of these tools. Since then, every time we needed a util, we added it to our stack. Lots more tools still to add, but so far we’ve got 15 like JSON converters to/from CSV, YAML, etc. You can check them out at jam.dev/utilities. It’s built with next.js, tailwind css, and shadcn/ui. It’s ad-free, open source, and all runs client side – data never leaves your computer. There’s a command K search powered by cmdk.paco.me. Are there any other tools that you wish existed or are there any other tools that like you've made for yourself like this? By the way, we’re hiring engineers and if you like building dev tooling, that’s our jam and we’d love to chat: jam.dev/careers

Hi HN! I've created [UFreeTools](https://www.ufreetools.com/), a collection of developer utilities (60+ tools and growing) that's completely free, ad-free, and runs entirely in the browser. No data leaves your device - everything is processed locally. ## Background As a developer, I found myself constantly searching for simple utilities like JSON formatters, UUID generators, and color pickers. Most existing options were cluttered with ads, required sign-ups, or sent data to servers. I wanted clean, fast tools that respected privacy. So I built UFreeTools as a modern SPA using…

Hey there HN! We’re Joe and Stopa, and today we’re open sourcing InstantDB, a client-side database that makes it easy to build real-time and collaborative apps like Notion and Figma. Building modern apps these days involves a lot of schleps. For a basic CRUD app you need to spin up servers, wire up endpoints, integrate auth, add permissions, and then marshal data from the backend to the frontend and back again. If you want to deliver a buttery smooth user experience, you’ll need to add optimistic updates and rollbacks. We do these steps over and over for every feature we build, which can…
