I second Vikunja. It’s very customizable. Tasks are saved in Projects, but then there are Saved Filters that can query one or more projects. That should fit your needs well. Fully open-source with a REST API and n8n integration too.
Definitely try the demo! I moved from Taskwarrior to Vikunja (Docker), mostly because I wanted Kanban boards and other GUI features for my GTD workflow.
