Your AI app works in the demo. The trouble starts when real people show up angry, confused, typing in another language, or trying to break it on purpose. AppTestSite puts your Gradio and Hugging Face apps through those moments before your users do, then shows you exactly where they hold up and where they fall apart.
Bring your own model and search keys. AppTestSite handles the hosting, the testing, the tracking, and the dashboards, so you stay in control of which models run and what they cost.
Simulate the users who give support bots trouble: the angry customer, the confused newcomer, the non-native English speaker, the deliberate breaker, and the one with oddly worded questions. You pick the model that plays them and the model that judges the results.
