Why I built 170+ browser-based tools to replace the bloated "Sign-up" utility sites.

I’ve spent the last few months building AllOmnitools, and I want to share why I took on this project.
We’ve all been there: You need to format a JSON file, check a Regex, or generate a CSS shadow. You search Google, click a top result, and then:
You get hit with a "Please sign up to see results" wall.
The page is 90% ads and 10% tool.
Worst of all, your sensitive data (like JWTs or Code) is being sent to a random server.
The Philosophy: Privacy-First & Client-Side
I decided to build a suite of tools where no data ever leaves your browser.
I’ve now reached 170+ tools including:
Dev Utilities: JSON Formatter, JWT Decoder, SQL Beautifier, and Git Cheat Sheets.
Design Tools: Glassmorphism Generator, CSS Loaders, and Navbar Builders.
Creator Tools: YouTube CPM Calculators and Safe Zone Overlays.
How it works technically:
Every tool is written in vanilla JS/CSS/HTML and runs 100% locally. If you turn off your internet, the tools still work.
I’m looking for feedback from this community. What tools are missing? What would make your workflow faster?
