Hi! For the ones of you that use Trello, I made a simple to use and host alternative in PHP. It's not a complete alternative like other projects, and I mainly made it to be able to host it on free PHP web servers while having control over data/attachments. It also support a basic importer for Trello JSON exports.
I'm hosting a test instance here, you can make an account to try it out (no email required):
Legacy software still requires maintenance.
Legacy dependencies still require to be used in new projects.
Dual booting multiple times a day is not feasible.
For those reasons none of my co-workers can fully switch to Linux.
