Thanks! Going oss was definitely about trust in the beginning -- people were more open to using the platform because they could see our codebase
Agreed that self-hosting billing can be a pain just cuz of how complex the whole system can be, which also means that it's prob p hard to debug / fix when something goes wrong. We don't see a lot of people self-hosting Autumn at the moment, but would be interesting to see that happen.
We've got a bunch of requests for a go sdk, so definitely on our roadmap to launch that soon!
DX is our bread and butter though, and we're fully focused on perfecting it for a single language (Typescript) before we start journeying into other languages!
