TL;DR — I built It's All Dev Tools : 50+ free developer utilities that run entirely in your browser . No uploads. No sign-up. Works offline. Built with Blazor WebAssembly + .NET 8 . 🚀

😬 Be honest… have you ever done this?

It's 6 PM. Something's broken in production. You grab a JWT from the logs, Google "jwt decoder" , click the first result and paste it in.

Then it hits you:

"Wait… where did that token just go?"

Most online tools quietly send your input to their server . That's fine for lorem ipsum. It's not fine for:

🔑 Access tokens and API keys

📜 Certificates

📦 API payloads with customer data

🧾 Internal config files

So I built the toolbox I actually wanted to use.
