Heard that name after such a long time. I recall encountering it over a decade ago. I recall the description and claims made on the site was much more “hyped up” than it is now.

Glad to see it’s still there.


Wow is it really that old? I hope the Chicago Boss team will drop by and give us some background on it, where it’s been and where it’s heading etc :sunglasses:

Yeah I remember Chicago Boss when it was brand spanking new! It had a lot of features and usability things in it but was a bit ‘too heavy’ for my projects so never got around to giving it a proper shakedown.

We don’t use Chacago Boss itself, but we do use boss_db as an ORM layer.


Wow, the memories! ChicagoBoss was my introduction to Erlang back in 2011. I think it was the version 0.3 or so :confused:
I liked it, but the company I was working on decided to drop/rewrite the project due to the lack of Erlang devs :frowning_face:
