Hello! Founder of Mintlify here - would love to hear what features were missing for your use case so that we can work on them.
I've had long conversations about our requirements at Cryptlex with Kate from your team but it has been a while since and I am aware that you have improved OpenAPI spec support greatly.
From whatever updates I have followed, I think Mintlify completely supports our use cases now but I'm not too sure if the packaging of the plans is well-suited for us.
I'll drop Kate another message after an internal discussion and we'll look into Mintlify again. Thanks for reading my naive exploration.
