Best Open Source Alternatives to Things3?

Asked by CasualCoder92
I've been using Things3 for a while because I really enjoy its user interface and the simplicity it offers for managing my calendar. However, I face a significant issue as it's locked to the Apple ecosystemโ€”there's not even a web app available. I'm looking for recommendations for good to-do list apps that are preferably open source. While I'm open to paid options, I'd like to avoid subscription models like Todoist and TickTick.

I get what you're saying about Things3 being locked to Apple. For something cross-platform, consider using Joplin. It's an open source note-taking app with to-do features, and it's available on various platforms. Plus, you can sync your notes across devices without the need for subscriptions!

If you're seeking an open source alternative, have you checked out Todo.txt? It's very simple and allows you to manage tasks using a plain text file. Another great option is Wekan, which is a Trello-like kanban board that's also open source. Both are user-friendly and donโ€™t tie you to any particular ecosystem!
