Last time I ran SNOW a few years ago, it was slowly but steadily heading into the SAP trajectory - highly-customazible per customer needs, expensive to pay and even more expensive to migrate onto. And it doesn't seem to prioritize any developer-oriented features to appeal to that crowd.

I.e., they have GitHub integration but it's not something I could convince a developer to use on a daily basis unlike Jira's one: https://docs.servicenow.com/bundle/vancouver-it-asset-manage...
