Bragging about my own: https://github.com/andrey-utkin/taskdb/ https://github.com/andrey-utkin/taskdb/ My take starts from the most backend thing - the database. Using PostgreSQL as data storage was a huge win, making all sorts of great features easy to do. Some highlights: * I use Grafana with my own defined metrics, and it was a piece of cake to set up; * I have two-ways sync with CalDAV calendaring, so I can see, and change scheduled date of a task in any calendaring app of my choice; * I can have full power of SQL data management using SQL interface apps like OmniDB.
