Logseq is opensource.

Lots of apps are too graphically flexible in how they allow content to be entered, placed, and formatted. They act like Word when what you want when authoring content is Markdown. Content and semantic structure, not graphical frills.

Logseq support Emacs Org syntax out of the box.

Checkvist hits a sweet spot between minimal and complexity. It gives you a host of options and extras to use on your lists, but you can completely ignore them if you don't need them and keep it very simple. This makes Checkvist a one-stop shop, regardless of what type of 'list' you need.

Search filters help you search for tasks by tag, due date, assignee, etc.

To-do lists often need to be grouped and regrouped for clarity. The outline-based nature of Checkvist makes it easy to move things across categories, to increase and decrease priority, etc.

Parses markdown, html links, hashtags to become formatted text, clickable links, and tags, respectively.

Checkvist offers many free features if you are using this individually.

Any item can have a free-text comment, which can be shown or hidden as desired.
