ChromeXt
ChromeXt adds userscript and developer tools support to Chromium-based and WebView-based browsers.
About ChromeXt
ChromeXt adds userscript and developer tools support to Chromium-based and WebView-based browsers on Android using the Xposed framework. It installs userscripts from URLs ending in .user.js, supports many Tampermonkey-style metadata keys and GM functions, and provides a web front end for managing scripts and editing them before installation.
It requires the Xposed framework, with LSPosed for root users and a patched-APK workflow for non-root users. Builds are distributed through GitHub Actions, which requires GitHub login, and installing a patched APK may require uninstalling the existing app.

ChromeXt FAQ
Does ChromeXt require the Xposed framework?
Yes. Root users install LSPosed first, while non-root users patch the browser APK with a modified LSPatch build.
How do I install a userscript?
Open a URL ending in .user.js to trigger the install prompt; canceling the prompt lets you edit the script and install it with the Install UserScript page menu.
For WebView-based browsers, what should the module be enabled for?
Enable it only for the browser application you wish to use, not for WebView applications or the Android system.
