Source: https://listme.name/best/to-do-list-apps/open-source

To-do apps differ on how much planning they support, which platforms they cover and whether they cost money. This ranking favors clear daily lists with reminders, then breadth of platforms, then planning depth and price. Free and open-source options are included where they are maintained.

## 1. Super Productivity (score 86.5)

A free, MIT-licensed task manager with time tracking, timeboxing and Jira, GitLab and GitHub integrations. Its focus is developer and deep-work use, so it suits plain shopping lists less well than Microsoft To Do.

## 2. Vikunja (score 82.0)

An AGPLv3 task manager with Kanban, Gantt and table views that you can self-host. Self-hosting needs your own server, and the hosted plans are paid, which makes it a poorer fit for casual use.
