App0
AI-native app builder that automates planning, coding, and testing while delivering a complete codebase you can export and own.
About App0
App0 is an AI-native application builder. For each task, you can choose GPT-5.6 or Claude 5; App0 automatically plans, codes, runs, tests, and fixes the project in an isolated development environment, ultimately delivering a standalone HTTPS preview and a complete, polish-ready, exportable codebase. Users own all code generated and exported through App0 and may modify, deploy, or commercialize it; each task runs in an isolated sandbox with its own workspace and transparent execution logs. Billing includes a free plan and a one-time 1-day pass purchase. Paid plans include unlimited conversations, and plans differ by the number of apps that can be created while the monthly fee stays fixed. It is suitable for independent developers, design studios, early-stage startup teams, and product and operations teams.
