Maskable.app is an online preview tool for PWA developers, designed to help check how maskable icons will appear before adding them to a Web App Manifest. The core value of a maskable icon is that it allows developers to provide a full-bleed icon, which the user agent then crops according to the device’s icon shape. On Android, this helps generate adaptive icons and reduces the visual disconnect caused by default white backgrounds.
Based on the captured text, it supports opening local icon files as well as loading icons via URL. The available preview mask shapes include None, Minimum safe area, Circle, Rounded Rectangle, Square, Drop, Cylinder, Squircle, Flower, Pebble, Vessel, Hexagon, and more. It also provides controls such as Shrink, Show ghost image, and W3C sample icons. Its functionality is highly focused: it is not a full PWA build platform, but rather a tool that helps developers determine whether key visual elements remain intact under different cropping shapes.
The tool mainly revolves around PWA, Web App Manifest, and the W3C maskable icon concept. It does not appear to be tied to any specific language or framework, so React, Vue, Angular, and vanilla Web projects can theoretically all use it during the icon design stage. The page includes an “Edit on GitHub” entry point, suggesting some level of community collaboration, but the captured text does not clearly mention a license, self-hosting options, API, SDK, or CLI.
The captured content does not mention pricing, subscriptions, or an account system, so its pricing status cannot be confirmed. In terms of usability, it is a ready-to-use tool: upload a file or enter a URL, select a mask, and view the result. The learning curve is low. Documentation is limited to a short explanation, which is enough to clarify the purpose, but it does not amount to a full documentation system.
Its strengths are that it is lightweight, intuitive, and directly addresses a common PWA icon adaptation pain point, especially for checking visual safe areas before release. Its limitations are that the scope is narrow: there is no visible support for batch generation, asset export, automatic manifest generation, team collaboration, or API integration. It is suitable for frontend engineers, PWA developers, designers, and small teams looking to improve the Android icon experience.
The captured text does not make it possible to determine network accessibility or payment availability in mainland China, so its access status is marked as unknown. If it is inaccessible, alternatives such as Chrome DevTools, Lighthouse, PWA Builder, or RealFaviconGenerator can be used to help check PWA icon configuration.
