CorentinTh/it-tools ? reverse-engineered prompt

Build me a website that's a collection of handy online tools for developers and IT people. I want it to be a sort of digital Swiss Army knife with a really great user experience. It should have tools like a JWT decoder, Base64 converters, hash generators, and maybe a UUID generator.

The design should be very clean, modern, and fast, with a dark mode option. I want it to feel like a polished, professional product. It should be built as a single-page application using Vue. Make it easy for me to add new tools to the site later on. Also, it's really important that this can be easily self-hosted, so please set it up to be deployed with Docker.
