Build mode for full-stack web and Android apps with Gemini.
Google AI Studio generates and iterates on full-stack web apps and native Android apps through prompts. Build mode uses components of the Antigravity Agent, manages multiple files and supports server runtimes, external services and two-way GitHub sync. It is not just a frontend prototype generator. Gemini allowances, API usage and Cloud Run resources require separate checks.
Full-stack Build mode, multi-file management and two-way GitHub support application coverage. Precision depends on Gemini and the project. A guided interface helps, but keys and security need setup; separate API and Cloud Run costs rule out a top value rating.
