Overview
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.
