Hoping someone will boot-up an open-source version. Linear seems to be the most popular alternative to Pivotal Tracker. What did you like most about Tracker? Thanks for the kind words!
As I recall there wasn't an abundance of notice of Pivotal Tracker's sunset, but I did kind of expect someone to come up with a more 1:1 open-source replacement with a one-step migration tool.
We looked at Linear and other options but ultimately ended up going with Shortcut. We wrote our own small migration script and moved over the old Pivotal IDs to keep as much historical context as we could. Shortcut's been a good tool overall, though I preferred Pivotal's Goldilocks level of compactness as far as the UI was concerned, as well as the general design.
Pivotal's API was tidy and integrated nicely into our development process. We have some git aliases such as `git start <branch>` where the branch name will end with a story ID by convention. The alias would do the work of creating the branch, setting the remote to the dev's fork of our repo, marking the story as started, and assigning the dev as the owner. It saved a lot of manual steps, so thank you for your involvement in the project which allowed such a nice workflow!
I would love to see an open-source one exist, potentially using open formats like Markdown / SQLite which could run locally or on a network share, and could potentially "live" inside of the repository.
I'm currently in LATAM, and often teach students - so having a no-cost tool which supports agile development would be so valuable (rather than having yet another tool to create a login for)
RIP Pivotal Tracker, and thank you for your involvement! It was a nice piece of software.
