https://taskwarrior.org/docs/commands/synchronize/ > The synchronize command, which first appeared in version 2.3.0, allows your Taskwarrior instance to share tasks with other instances. You can have several instances making local changes all of which sync to a single server, and they will all be kept up to date, with changes flowing from instance to instance. $ task sync Syncing with foo.example.com:53589 Sync successful. 1 changes uploaded. There was a site inthe.am which provided sync service. While that's been shut down, the code is available on https://github.com/coddingtonbear/inthe.am - the local hosting wasn't ever finished or not designed with that in mind ( https://github.com/coddingtonbear/inthe.am )

Looks like a self-hosted taskserver is the way now: https://github.com/coddingtonbear/inthe.am : > Note:: Inthe.AM will be shutting down on January 1st, 2024. See #427 for more informaion. Looks like there are a number of ways to sync over just git now? https://taskwarrior.org/tools/ - [ ] DOC: taskwarrior-flutter: add the 'taskwarrior' topic label https://github.com/topics/taskwarrior

Have you ever looked at task warrior? https://taskwarrior.org (and you could host it online yourself (I believe) with inthe.am - https://github.com/coddingtonbear/inthe.am if you aren't comfortable with the existing version) It's well documented ( https://taskwarrior.org/docs/ ) had enables a number of different workflows and export and import options (I've dabbled with jira imports to task warrior for my own sorting views).

Also check https://github.com/coddingtonbear/inthe.am You can use their hosted version or host your own.
