Ask HN: Must have Web app tools like gitlab, graylog, etc

Hey guys, I was wondering what tools everyone is running in their organizations.

I have been running gItlab since the summer and I just recently discovered graylog. These two tools are so fundamentally useful they have completely changed the way we work. We stumbled upon airbrake recently and probably will be giving that a try soon.

Our scm is git, builds are with maven, stored in nexus. We don't have ci yet, or anything that monitors performance, or an agile project management suite.

Anyway, I'd love to hear what's out there. Thanks!
