General development tools

I've created some tools that have helped me while developing interactive websites. Since I've learned a lot from other developers, I made these tools free for everyone to use. These tools respect your privacy (I don't datamine or sell/give the data to anyone).
You can find these tools at:
https://tools.feron.it/

At the moment there are 3 tools available:

• Get your IP
• Check if a site is up and running
• Json viewer/visualiser

When I create an other tool that might be useful for other people I add it to this site.

If you have any questions or remarks or may a request for a tool, please use this thread
