Sure there is. JavaFX ships a WebView component (literally called that) which runs on every platform including embedded. It's WebKit-based. You don't like WebKit but at every point in the web's history there were some browsers with more features or fewer bugs than others. If you're writing web apps then you're meant to run on more than one rendering engine. At any rate there's also JCEF, again for JVM apps. https://github.com/JetBrains/jcef It embeds Chromium.

It would be, were JetBrains IDEs currently compatible with the latest JDK, but they are not, so it's not quite as simple as that, unfortunately. IDEA and CLion won't start with JDK 16 or later, so I'm using JDK 15 for those. All the other JetBrains IDEs work with JDK 16. In all cases, features using the JCEF [1] runtime library, which is bundled with the JBR [2], will not be available. I'm using these options on Debian/unstable on all JetBrains IDEs, with both JDK 15 and JDK 16. -XX:+IgnoreUnrecognizedVMOptions -XX:+UnlockExperimentalVMOptions -XX:+UseZGC -XX:-UseG1GC -XX:C1CompileThreshold=100 -XX:C2CompileThreshold=5000 -Xms4G -Xmx4G -XX:ReservedCodeCacheSize=512m -XX:SoftRefLRUPolicyMSPerMB=50 -XX:CICompilerCount=2 --illegal-access=permit Adding -XX:ReservedCodeCacheSize= and -XX:SoftRefLRUPolicyMSPerMB= made

all the difference in keeping heap usage down. I have not yet experimented with different values for those parameters. The option --illegal-access=permit is required on JDK 16, but this option was removed in JDK 17, and because of this (but probably not only this) I haven't yet been able to make any JetBrains IDE work with JDK 17. In adjusting all of these settings, YMMV depending on your system. Good luck! [1] https://github.com/JetBrains/jcef [2] which is currently based on JDK 11
