Tail Lens – Tailwind editor in browser
Hey HN - I built Tail Lens, a browser devtool that lets you click any element and tweak its Tailwind classes right on the page. Changes appear instantly, so you can see results as you edit. Smart class suggestions, Tailwind v3/v4 + JIT support, and quick element navigation and many more. Based on early feedback, I am working on a feature to live sync changes to React/HTML files, so tweaks persist after a full reload. Link -> https://taillens.io. Happy to hear any feedbacks
In plain words
Tail Lens is a browser developer tool that allows users to select any webpage element and modify its Tailwind CSS classes in real-time, with changes displayed instantly. It supports Tailwind v3 and v4, includes JIT compilation, offers smart class suggestions, and provides quick element navigation. The tool is designed for developers working with Tailwind CSS who want to experiment with styling directly in the browser without editing source files.

Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…

Hey HN! Pilots everywhere are required to keep a logbook of all their flying hours, aircraft, airports, and so on. Since I track everything digitally (some people still just use paper logbooks!), I put together some data visualizations and a few 3D globes to show my flying history. This globe is probably my favourite so far: https://jameshard.ing/pilot/globes/all If you’ve got ideas for other graphs or ways to show this kind of data, I’d love to hear them!

I was the main contributor to workout.lol, an open-source fitness app to easily build a workout routine. The project had traction (1.4k GitHub stars, 95 forks, ~20K visits/month), but was eventually sold due to video licensing hurdles. The new owner stopped maintaining it, and the repo went abandoned. Over the next 9 months, I sent 15 emails to try to save it : no replies. Feature requests & issues were ignored. The community was left with a "broken" tool let's say. I couldn't just let it die So I built the new version from scratch with the same open-source spirit, but a better…
