The person behind Sunasty
Hi, I'm Bastien. I make Sunasty.
Who I am
I'm a developer, currently between jobs. Instead of sitting around waiting for the next one, I decided to build something people might actually use.
Why I made this
It started with a small annoyance. I wanted to resize an image, so I found a website, uploaded the file, and got my result. Then it hit me: I'd just handed a personal photo to some company's server for a job my laptop could have done in a fraction of a second. That bothered me. So Sunasty does the opposite. The tools run on your own machine, nothing gets uploaded, and if you cut your internet they keep working anyway.
The promise, in plain terms
I don't want your files. More than that, I built the site so I couldn't take them even if I wanted to: no upload, no account, no tracking. Don't take my word for it. Open your browser's Network tab and watch, your file stays put.
Off the clock
When I'm not writing code, I'm playing old games, shuffling Yu-Gi-Oh cards, or hanging out with my cat. He's the one the logo is based on.
Say hi
It's just me running Sunasty. Found a bug, or wishing a tool existed that doesn't yet? Tell me about it. I read everything. Get in touch
