Ruby on Rails is awesome to write, horrible to maintain. It’s the fastest way to build a web app but good luck with staying productive once you have 100 engineers working on it and a million lines of rails soup to wrangle.

GutHub, Shopify, Coinbase, Square, AirBnB, etc. , can probably answer some of your concerns.

GitHub feels super slow so I can't say I'm all that surprised to hear it's a rails app.

Gitlab is also Rails :) But wait it's probably super slow. You should try Jira heard it was wriiten in Java. Must be a fast app then.
