Amazing coincidence! I've been working on a project using OpenAPI at work and have come across several of your blog posts. I've been testing both oapi-codegen and ogen. Lots to like about both but, while oapi-codegen doesn't have a "proper" website, its docs and examples are much more comprehensible. That and adding std lib http support is just amazing.
I may have some contributions to make based upon internal tooling that I wrote to enable enable support for external refs and the like. Have to check-in with legal once I've got the current project out the door.
Thanks for all of your work!
