What FirstApp is

FirstApp is a web service that turns plain-language descriptions into working web applications. It plans an application architecture and generates production code for a frontend, backend, and database. While chatting, you can open an interactive preview, refine the result, and then deploy it with one click to a global edge network. Custom domains can be connected with automatic HTTPS. The stated workflow runs from describing an app through preview and refinement to a hosted, shareable application. FirstApp’s example is a yoga studio booking app with schedules and Stripe checkout. The service is paid but includes a free plan, and its homepage says building can start without a credit card. It supports web apps and hosted deployment, not mobile apps. Prompts and project context are processed by its AI infrastructure; the company says these are not used to train third-party foundation models. Terms caution that generated output may be inaccurate or unsuitable, so users must review and validate applications before deployment.
