Trunk Merge (opens in new tab)

Trunk Merge is an intelligent service that orchestrates merging pull requests to maintain a repository of code that always passes tests. Airbnb, Uber, Twitter, Robinhood, and many other big tech companies internally have their own sophisticated merge queues. Now, you can get the same thing without having to build it.

Looks like in theory it works similar to other solutions I've seen, although those rarely get the polish I see in the video (since they're internal tools).

Interesting. Having worked at Uber I've been curious why there aren't more of these types of services available to the public.
