What Hydrogen Browser is

Hydrogen Browser is a free, open-source mobile browser for Android, based on WebView and released under the MIT License. Its listed browser functions include basic web browsing, address bar search, and popup menus. Users can change the search engine and homepage, while the address bar menu provides back, forward, home, and settings controls. The v0.4.0_alpha release adds tab management through a dropdown menu. That release is a rewrite using Jetpack Compose and Material 3, with dynamic color support on Android 12 and later. The release is marked as a pre-release and warns that it may be unstable or broken, so the listed version should be approached as an early release rather than a settled one. Earlier release notes also identify incorrect display in dark mode as a known issue. The GitHub Releases page lists three assets for v0.4.0_alpha. The repository owner is identified as sileneer (zihao).
