Hey there! I'm the author of Ash Framework, happy to answer any questions you have. A few people have deployed to production with Ash and are seeing good results, but it is definitely at the "sharp edges" phase, where its great if you're okay with hanging out in our discord and troubleshooting, and even better if you're the kind of person who can dive in and PR whatever change is needed.
Feel free to join the discord as well if you just want to follow along: https://discord.gg/WZCECgMe
