Hi

I have created a website with web tools for programmers: http://fordev.online/#/info
Currently it contains tools for base64 encoding/decoding, JSON viewing/editing and calculating sha256 hashes.

I would appreciate any feedback. Feel free to write what would be useful for you.
It's just a start but I have many ideas for next features like making history for all features, add more features according to users expectations, and many more.
