Show HN: Mintlify Ignored This Feature Request for 6 Months. Here's My Solution

Mintlify users have been begging for pre-filled API playground fields for months. The GitHub discussion has people literally saying "I just lost two hours of my day banging my head against this issue." (https://github.com/orgs/mintlify/discussions/759) The problem? When you click "Try it" in Mintlify's playground, every field is empty, even though your OpenAPI spec has perfectly good example values sitting right there. Your developers have to manually type or copy-paste data just to test a single endpoint. It's 2025. This is insane.

So we built madrasly. Run

npx madrasly your-spec.json output-dir

and you get a fully interactive API playground with all fields pre-populated from your OpenAPI examples. Path parameters, query params, request bodies—everything just works. One command, zero configuration, and your developers can actually test your API without wanting to throw their laptop. Check out the live demo or grab it from GitHub. If Mintlify won't fix it, we will.

Feel free to star us on GitHub! We also offer free hosting on our website (no paid tiers available). madrasly.com.
