Browser Compatibility
Minimum browser versions supported by Berdee.
Berdee supports modern evergreen browsers. The minimum versions below are based on the frontend toolchain and the browser APIs used by the Studio and learner experience.
| Browser | Minimum version | Release date | Notes |
|---|---|---|---|
| Chrome / Chromium | 111 | March 7, 2023 | Matches Vite's modern default target and Tailwind CSS v4's minimum Chromium support. |
| Microsoft Edge | 111 | March 13, 2023 | Edge 111 is the Chromium-aligned stable release for this support floor. |
| Safari | 16.4 | March 27, 2023 | Required for Tailwind CSS v4's modern CSS feature baseline. This also applies to iOS Safari and iOS WebViews. |
| Firefox | 128 | July 9, 2024 | Tailwind CSS v4 sets Firefox 128 as its minimum supported Firefox release. |
Internet Explorer and legacy mobile browsers are not supported.

Why these versions
The app uses browser-native platform features such as modern CSS color syntax, CSS cascade layers, ResizeObserver, structuredClone, crypto.randomUUID, drag-and-drop APIs, media playback, canvas, and modern JavaScript output. Vite does not add broad runtime polyfills by default, so browsers need native support for the modern web platform features Berdee relies on.
Tailwind CSS v4 is the limiting compatibility floor for CSS support. Vite's default production target is also modern-browser-only, with a lower Firefox floor than Tailwind.
