Thank you, I indeed spent quite some time on brushing up the UI. Regarding the source, it isn’t public. It’s a business, and the one-time optional extras pay for it. Nonetheless, if self-hosting is a hard requirement, I would agree that Super Productivity or Vikunja are better choices. I tried them myself and they work pretty well. If you have improvements in mind, I’m happy to hear them!

Thank you! I really appreciate it! Technically, nobody even has to buy anything. The most important features are free and there are no limitations.

Nice find, hadn’t seen this one. One gap I noticed: the task management category is all team and project tools. Nothing for a plain personal to-do list or day planner, which is what most people leaving Google Tasks or Microsoft To Do actually need.

Disclosure: I build one, OmmiQ (ommiq.com), a day planner made and hosted in Germany. Free, no subscription, no tracking. I’ve just submitted it there. If anyone knows other European personal to-do apps, post them too.
