After more than 10 years, @jazzband is sunsetting.

I started it in 2015 because maintaining Open Source alone was exhausting. The idea was simple: shared access, shared responsibility. It's been an honor to watch it grow: 3,135 members, 84 projects, and a lot of code shipped together.

GitHub's slopocalypse made the open membership model untenable, but the cracks were older than that. I was the only roadie for the entire run and never managed to fix that. The full story, with 10 years of data and some honest reflection:

If you maintain a @jazzband project, expect an email before @pycon. django-commons is a great option if you're looking for a new home, they've already taken on several projects and got the governance right from day one.

@jezdez Thanks for the attempt, even though this particular experiment didn't work out in the long run. I'll consider potential homes for contextlib2 (I have a couple of ideas already), and likely check in with the pip-tools folks as well.

@ancoghlan It's been my pleasure :) I thought you might have ideas, thanks! I haven't started the email run yet, but if you have ideas, it'll be easier to coordinate.
Show threadAlyssa CoghlanMar 14
@jezdez My ideas are fairly specific to those projects rather than being generally available options (contextlib2 will likely find a home with core dev, the PSF, or OpenStack, while pip-tools presumably has a potential home under PyPA)

@ancoghlan Seems reasonable to me!

@jezdez

Thank you for Jazzband. Iโ€™ve several used projects from there and made some minor contributions. Django and Python have gained a lot from Jazzband over the years.

@jezdez @jazzband this post you linked to, looks like an llm bot posted it: https://byteiota.com/open-source-maintainer-crisis-60-unpaid-burnout-hits-44/ (see the bottom for its own seo summary) and I donโ€™t believe there are 300m companies on GitHub

@jezdez @jazzband Thank you for all your work! Everything you wrote makes sense to me, and highlights just how much more progress needs to be made for us to find sustainable ways to do Open Source.

@jezdez @jazzband It was a long and pioneering journey. Thank you for your service and >100 projects is an accomplishment.

@jezdez @jazzband thank you for everything you've done and continue to do for our communities Jannis! Jazzband was one of the ways I got into open source in the first place ๐ŸŽท

@CodenameTim @jazzband Right back at you, Tim! I feel positive about Open Source communities having an impact, not their fault if platforms change. Thank _you_ for participating and pushing

@jezdez thanks for starting and continuing @jazzband for so long. I've really enjoyed the interesting conversations it's inspired over the years about how to handle under-maintained open source projects.

@treyhunner @jazzband Likewise! Luckily there are more of those projects, so we can have more interesting conversations :-) See you in Long Beach?

@jezdez @jazzband Thank you, that was a good read โ€” a gracious, thorough sendoff for an important project. It all makes sense. The roster of projects is amazing, the legacy is secure.

Hey @jezdez thanks for creating @jazzband and for showing to the community an alternative way to sharing responsibility. It has been a great success. ๐Ÿ’ช

@jezdez @jazzband Thank you for everything you did with Jazzband. It *was* important work, and continues to be; but the work didnโ€™t *have* to be done by you, and a graceful handover is a fitting way to end a grand project.

*This* gig may have ended, but that doesnโ€™t mean we stop playing music. Iโ€™ll keep wearing my tour shirt and remember the great shows along the way.
