About Me

This was built by me, Alicia Sykes (@lissy93 on GitHub). I'm an open source developer, passionate about Linux, security and the web.

I build free and open source software for the developers, sysadmins and sometimes humans. My objective is to build tools that respect a user's privacy and are accessible to everyone. I have a particular interest in security, Linux and self-hosting. But also just love to build things that are fun and (sometimes, maybe) useful.

Sponsorship

I have developed, open sourced and maintain 100+ applications and libraries, used by over 1 million people every year. And pretty much everything I build is free to use, open source, and without ads, tracking or paywalls. Because I believe software should be free and accessible to everyone.

But running these projects does cost money. And maintaining them takes time. So, if you've found this app useful, please consider sponsoring me. My sponsors mean the world to me, and it's because of their generosity that this app can remain free for everyone.
