F12
thef12app
F12 is an all in one developer toolbox. It tries to give you all the tools that you need as a developer. We currently have: Unix time converter + timezone converter, JWT Decoder, Base64 Encoder / Decoder, URL Inspector / Constructor, KeyCode Finder and JSON Formatter. We're working on adding more tools in near future. Our aim is to provide a safe set of tools where your sensitive data doesn't leave your browser. You don't have to paste your JWT into that fishy website ever again.
