> It became the foundation for numerous successful companies - Airbnb, Shopify, Github, Instacart, Gusto, Square, and others. Probably a trillion dollars worth of businesses run on Ruby on Rails today.
Do those companies still run their businesses on RoR? My impression was that companies started out with it, but migrated to something more robust as their traffic grew.
Shopify made the new Ruby JIT compiler. [0] They're on the Rails Foundation, as is 1Password, among others.
Stripe is still in on Ruby too; they're behind the Sorbet gradual type system, and Ruby is a first-class language for working with their API.
I always hear the stereotype of companies starting on Rails and migrating later, and I think it sticks around because it makes some level of intuitive sense, but it doesn't actually appear to happen all that often. I guess successful companies don't see the need to rewrite a successful codebase when they can just put good engineers to work on optimising it instead.
