Thinking of adding a feature to directly connect api so my backend folks never have to learn bloated frontend frameworks for simple tasks. It can be used for internal presentation, MVP etc where you don't want a complex ui. Checkout the Twitter post : https://x.com/AnuttamAna56189/status/1808423300571316500?t=2...
