BananaStudio: Full-Resolution Nano Banana Image Studio Inside Gemini Canvas

Z3ROCOOL22 · reddit · 2026-09-29

Frustrated by Gemini's compressed image previews, a developer built BananaStudio, an image creation app that runs inside Gemini Canvas using your own account. It offers multi-model switching (Nano Banana 2 via account quota with no API key, Nano Banana Lite and Gemini 3 Pro Image via key), full native-resolution rendering (1K/2K/4K) with lossless PNG download, Style Gems with up to 10 persistent reference files, session-wide master directives, brush-based inpainting with binary masks, auto aspect-ratio matching, a zoomable lightbox with server telemetry, bilingual UI, and local history.
