Unlikely.

1. I no longer work at Airbnb, so I can't help you there.

2. The wrapper is somewhat deeply embedded in the dev tools swiss army knife, and is written in Ruby, so (a) it's difficult to extract since its tied with other Airbnb specific concerns and support libraries, and (b) distributing perf-sensitive Ruby code to end-users is challenging so you might not want it anyways.

You might want to take a look at Mutagen, a unison replacement written in Go which seems to avoid most of what makes Unison annoying to work with. I haven't tested it, though, so I can't vouch for it.

That makes sense. I hadn't heard of Mutagen before, but it seems like it would solve a lot of the issues that drove me away from Unison. Thanks for mentioning it!

Here’s a similar project we made for syncing stuff to remote docker hosts:

Very cool. I always thought a node/TypeScript implementation would be easier than our Ruby one because of the natural event-orientation of Node.
