I shared a previous version of yapi a few months ago in the comments section of a post talking about the insanity of Postman being 'down'. yapi has developed into a more mature project since then!

Still very early, but it makes me much more productive vs Postman, Bruno, Insomnia, etc.

If youre a nvim/tmux culture human, you might like this!

This is a really interesting approach! How did you end up deciding on executable markdown as opposed to other approaches?

well - the point is. that we wanted to be standards compliant - and want to use existing technologies without actually reiventing a new standard or a proprietary format. (like some of the other api clients took).

and moreover we had this fundamental idea that documentation and testing should be in a single source of truth to avoid documentation drift (not just the spec drift).

And hence we came up with the idea of using markdown as the baseline and doing everything around it.

Love this.

As a literate code aligned shop, we wish more tools adopted these values for knowledge-base-adjacent tasks.

// Love OP's CLI too!

Looks neat! I highly recommend showcasing the interactivity with a few GIFs in your README. You can script them with https://github.com/charmbracelet/vhs

Very nice. Just did not find the spec/format for the config file.
