Created 60 free useful tools in one place
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.

Toolbrew – Free little tools without signups or ads2025 · toolbrew.co · ▲269I got tired of fighting through spammy tool sites just to do something simple, so I made Toolbrew in a few hours on Replit. Just a bunch of free little tools in one place. Text converters, SEO checks, video downloaders, that kind of stuff. No signups, no ads. If there is a tool you wish existed, you can request it on the site and I will build it. Do your worst. Seriously, ANY tool. Maybe it helps, maybe not. Enjoy!

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…

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…

Hello HN! Being a software engineer and an SEO guy I wrote a heap of tools and scripts to make my life easier. Now I've decided to share some of them with the community, and made a small site where I will be publishing them. They are all completely free (yes, free forever) and you don't even need to sign up for the site. Just use the thing as you like, no limits. Currently you can access 4 instruments: - Backlink retriever - Thin/weak content analyzer - Traffic trend analysis - Visitor list retriever I am planning on releasing more free tools with time, and trying to stay original by…

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…

I built the world's most impractical 1000-pixel display and anyone in the world can draw on it. It draws a single pixel at a time and takes 30-60 minutes to complete a single image. Anyone can participate in the project by voting for the next image to be drawn, and submitting images. https://kilopx.com/

Kitten TTS is an open-source series of tiny and expressive text-to-speech models for on-device applications. We are excited to launch a preview of our smallest model, which is less than 25 MB. This model has 15M parameters. This release supports English text-to-speech applications in eight voices: four male and four female. The model is quantized to int8 + fp16, and it uses onnx for runtime. The model is designed to run literally anywhere eg. raspberry pi, low-end smartphones, wearables, browsers etc. No GPU required! We're releasing this to give early users a sense of the latency and voices…

I was wondering how I can arrange objects along a spherical helix path, and read some articles on it. I ended up learning about parametric equations again, and make this visualization to document what I learned: https://visualrambling.space/moving-objects-in-3d/ feel free to visit and let me know what you think!

For HTML Day 2025 [1], I made a web service that displays the current sky at your approximate location as a CSS gradient. Colours are simulated on-demand using atmospheric absorption and scattering coefficients. Updates every minute, without the use of client-side JavaScript.
