When working with APIs, I noticed that getting from “API docs” to a working app often takes hours or even days. You need to read through documentation, figure out authentication, and piece together example code before you can even test if the API fits your use case.

I wanted to make this faster, so I built SampleApp.ai. It lets you type in a use case (e.g. “build a price tracker with this API”) and automatically generates a runnable sample app in under 60 seconds. The playground comes pre-wired with authentication, API calls, and example UI (depending on the API/SDK) so you can start experimenting right away.

The idea is to help API providers give developers a “time-to-first-app” experience instead of just “time-to-first-call.” It can be embedded directly in API docs or used standalone for onboarding, sales demos, or internal integrations.

You can try it here: https://statsig.sampleapp.ai, https://groq.sampleapp.ai

Our main website is here: https://sampleapp.ai

I’d love feedback from API developers and providers — what’s missing, what’s confusing, and what would make this genuinely useful for your workflow?
