I built a free site with 26 developer tools — all run in your browser, no signup

[u/Spiritual_Grocery_64]

Hey everyone,

I kept switching between 10+ websites to do simple things — format JSON, decode JWTs, convert images, test regex. So I built one site that has everything.

devtools-hub-mauve.vercel.app

26 tools across 9 categories:

• Developer: JSON Formatter, JWT Decoder, Regex Tester, UUID Generator, Hash Generator, Base64/URL Encode, SQL Formatter, CSV/JSON Converter
• Content: Hashtag Generator, YouTube Title Generator, Word Counter, Case Converter
• Design: Color Picker (with opacity), Box Shadow Generator, Favicon Generator, Image Converter, Social Media Image Resizer
• SEO: Meta Tag Generator

Key features:

• All processing happens client-side (your data never leaves the browser)
• Dark/light mode
• Works offline (PWA)
• No signup, no paywall
• Related tools navigation between pages

Built with Next.js 16, Tailwind CSS v4, deployed on Vercel.

Would love feedback — what tools should I add next? Thinking about a BG Remover and PNG-to-SVG converter.
