How do you handle your API documentation right now?

I’m working on a lightweight alternative to GitBook/Mintlify for indie devs and API-first startups. Curious:

- Are you using GitBook, Mintlify or something else for your API documentation ?

- What do you think its broken or annoying in your current setup ?

- Would you pay for either a better tool or done-for-you setup service?

I’ve talked to a few founders who say they avoid docs until it become serious problem, curious what about your preferences ?
