Geyser

Pros of Velocity

• Designed specifically for proxying Minecraft servers, offering optimized performance
• Supports multiple backend servers, allowing for load balancing and seamless server switching
• Extensive plugin API for customization and additional features

Cons of Velocity

• Limited to Java Edition servers, lacking cross-platform support
• Requires additional setup and configuration compared to standalone servers
• May introduce slight latency due to the proxy layer

Code Comparison

Velocity (Java):

@Subscribe
public void onProxyInitialization(ProxyInitializeEvent event) {
    logger.info("Velocity plugin initialized!");
}

Geyser (Java):

@Override
public void onEnable() {
    this.getLogger().info("Geyser plugin enabled!");
}

While both projects use Java, their code structures differ due to their distinct purposes. Velocity focuses on proxying and server management, while Geyser emphasizes cross-platform compatibility between Bedrock and Java editions.

Velocity excels in managing multiple Java servers, offering advanced proxying features. Geyser, on the other hand, bridges the gap between Bedrock and Java editions, allowing cross-platform play. The choice between them depends on specific server requirements and whether cross-platform support is needed.

Pros of BungeeCord

• Mature and widely adopted proxy solution for Minecraft servers
• Supports a wide range of Minecraft versions
• Extensive plugin ecosystem for customization

Cons of BungeeCord

• Limited to Java Edition servers only
• Requires more setup and configuration compared to Geyser
• May have performance overhead for large server networks

Code Comparison

BungeeCord (Java):

@EventHandler
public void onServerConnect(ServerConnectEvent event) {
    ProxiedPlayer player = event.getPlayer();
    ServerInfo target = event.getTarget();
    // Handle server connection logic
}

Geyser (Java):

@Subscribe
public void onBedrockClientConnect(BedrockClientConnectEvent event) {
    BedrockClientSession session = event.getSession();
    // Handle Bedrock client connection logic
}

Both projects use event-driven architectures, but Geyser focuses on Bedrock client connections while BungeeCord handles Java Edition server connections. Geyser's codebase is more specialized for cross-platform compatibility, while BungeeCord provides a broader proxy solution for Java Edition servers.

Pros of PocketMine-MP

• Designed specifically for Minecraft: Bedrock Edition, offering better performance and compatibility
• Extensive plugin ecosystem tailored for Bedrock servers
• More customizable and flexible for Bedrock-specific features

Cons of PocketMine-MP

• Limited cross-platform compatibility, primarily focused on Bedrock Edition
• May require more setup and configuration compared to Geyser's proxy approach

Code Comparison

PocketMine-MP (PHP):

$this->getServer()->getPluginManager()->registerEvents($this, $this);
$this->getScheduler()->scheduleRepeatingTask(new ClosureTask(
    function (): void {
        $this->getServer()->broadcastMessage("Hello, world!");
    }
), 20 * 60);

Geyser (Java):

@Subscribe
public void onServerStart(GeyserStartEvent event) {
    GeyserImpl.getInstance().getBootstrap().getGeyserLogger().info("Server started!");
    GeyserImpl.getInstance().getBootstrap().getGeyserConfig().saveConfig();
}

The code snippets demonstrate different approaches to server management and event handling in their respective languages and frameworks.
