what alternatives to google.android.webview do we have?
are there any actual open source apps that i can install to replace it?
Isn’t that for developers to replace reliance on webview rather than users to replace their webview implementation?
There was bromite but that seems to have died. open webview has some similar webview replacements I think, but I havent gotten it to install yet so can’t promise anything.
If you are rooted with Magisk then you can install an alternate webview. As mentioned the Bromite webview is stalled. Mulch webview (from DivestOS) is regularly updated and has been added to Open WebView module.
I use Mulch SystemWebView Overlay on my ROMs. It is a straight flashable zip but with alternate ways of installing if it does not work (like via adb). A Magisk module is also available. I use Mulch webview on all ROMs including Oreo. I do not run OEM stock so no comments/ideas on that front.
Once the webview is installed and visible it can be updated regularly using your preferred F-Droid client with Divest OS repo added.
If I remember correctly GrapheneOS develops their own chromium fork called Vanadium, that also provides a webview. I don’t know if it’s installable on other ROMs tho
