I got tired of Googling the same tools every day, so I built my own collection

You know that moment when you're deep in a debugging session and you need to quickly decode a JWT, or format a messy JSON response, and you end up with 6 browser tabs open across 4 different websites?
That was me. Every single day.
Some sites were slow. Some had aggressive ads that made the page unusable. Some required an account just to paste a string. And half of them looked like they hadn't been updated since 2009.
So I decided to just build my own.
Introducing MyDevSuite, 10 free browser-based developer tools, no login, no tracking, no nonsense.
Everything runs client-side. Your data never touches a server. It's just you and your browser.
Here's what's in it right now:

🔧 JSON Formatter & Validator
🔐 Base64 Encoder / Decoder
🔑 JWT Decoder
🔗 URL Encoder / Decoder
🆔 UUID Generator
⏱ Unix Timestamp Converter
🎨 Color Converter (HEX / RGB / HSL)
✅ Regex Tester with live highlighting
📝 Markdown Previewer
⏰ Cron Expression Builder

The whole thing is plain HTML, CSS, and vanilla JS — no frameworks, no build step, no dependencies. I wanted it to be fast and I wanted it to stay fast.
I'm planning to keep adding tools over time. If there's something you reach for constantly and wish had a clean, fast, no-BS version — drop it in the comments. I'll probably build it.
Would love any feedback on the UX, the tools themselves, or anything that feels off. Be brutal, I can take it 😄
