Show HN: CtrlTool – 132 free online tools for developers and everyday tasks

https://ctrltool.wtf
2•jetroni•36m ago
Hey HN, I built CtrlTool because I kept needing small tools for random things and didn't want to install something or sign up for another website.

It currently has 132 tools for things like JSON, JWT, Base64, URLs, text, hashes, PDFs, SEO, converters, generators, and other everyday stuff.

The main thing I tried to focus on is making the tools fast and simple. For tools where it makes sense, everything runs locally in the browser so the data doesn't need to be uploaded to a server.

It's still very new, so I'm mostly looking for feedback on the UX, which tools are actually useful, and what you think is missing.

https://ctrltool.wtf

Would appreciate any feedback.
