OpenJDK 17 & 21 Support
Java bots require modern runtimes to utilize features like Records and Pattern Matching. VisiHost's Docker containers provide native support for OpenJDK 17 and OpenJDK 21. Simply upload your compiled `.jar` file and specify the startup command.
JVM Memory Management
Unlike standard free hosts that crash when Java performs Garbage Collection, we allow custom JVM flags. You can configure your startup command with `-Xmx` and `-Xms` arguments directly in our panel to optimize heap allocation and prevent OOM (Out of Memory) kills.
Perfect for JDA & Discord4J
Whether you've built a music bot with JDA + Lavaplayer or a complex moderation system using Discord4J, our persistent networking ensures stable WebSocket connections to Discord's API gateways. Zero sleep mode guarantees that your event listeners are always active.
