author of Lucky here. Would love to hear what you don't like about Lucky's ORM (Avram). It is not quite as feature complete as ActiveRecord, but in some ways it has more features (like being able to do more advanced queries in Crystal `>`, `ILIKE`, etc.
But both are still very early stage of dev. Is Amber still being developed?
Edit: Looks like Amber had a new release a few days ago, and GitHub got a new design?
