Hey Product Hunt! 👋 I built DevToolsCave because I kept running into those tiny developer tasks that take only 30 seconds — but somehow still require opening 3 different websites, finding the right tool, dealing with ads, or pasting data into a service you don't really want to trust. So I started building my own collection. It has grown to **45+ tools** already, covering everything from JSON/JWT/log utilities to converters, generators, analyzers and visual tools. One principle I'm particularly trying to stick to: **if a tool can work entirely in the browser, it should.** That means less waiting, fewer dependencies, and better privacy for things like logs, tokens and data. This is still very much a work in progress, and that's actually what I'm hoping to get from Product Hunt today: **What developer task do you find yourself doing repeatedly that deserves a really good tool?** Tell me below — the best ideas may become the next DevToolsCave tools. 🛠️
