App0 homepage screenshot, coding AI tool

Our take: App0 suits solo builders and small teams who want a full-stack app generated from a written brief with GPT-5.6 or Claude 5 models, a live HTTPS preview and exportable code.

Main limitation: Free plan allows 1 app and 5 conversations per month; day and weekly passes cap at 5 apps and one model; subscription prices were not visible on the fetched page.
