VaporBoy review
A free, open-source web emulator with flexible input and cloud ROM loading.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
VaporBoy is a free, open-source Progressive Web App for playing Game Boy and Game Boy Color games in a web browser. It is aimed at people who want browser-based play across desktop and mobile devices without installing a traditional emulator. ROMs can be loaded from a local device, preloaded open-source sources, and supported cloud services. The interface supports keyboard, touch, and gamepad input, with responsive layouts for desktop and mobile screens. VaporBoy runs on the web and supports browsers including Chrome, Firefox, and Safari.
The feature set covers the main needs of a browser-based emulator. Configurable emulation settings, save states, and video and audio effects provide control beyond basic ROM playback. Progressive Web App installation can also make the browser-based tool easier to access from a device. Google Drive integration adds cloud-service ROM loading, while local ROM loading keeps the workflow flexible. These options make VaporBoy a practical fit for users who value multiple input methods and access across screen sizes.
VaporBoy is free, with no paid tier to evaluate. Its focus is narrow: Game Boy and Game Boy Color emulation through the web rather than a broader platform library. The project is still in beta, and ROM compatibility may vary. It also lacks RTC and netplay features, so users looking for those capabilities should choose another emulator. Pick VaporBoy for accessible browser play, save states, cloud integration, and PWA installation; avoid it if you need a non-web platform or multiplayer and real-time clock support.
