Features

This page gives a quick overview of Sea Lantern's current capabilities and practical use cases.
If you're getting started, begin with "Server Creation", "Java Management", and "Console".

Console

• Real-time server log output for both startup and runtime stages
• Direct command input with command history and quick command panel
• Toolbar actions for common tasks like clearing view and exporting logs

server.properties Editor

• Edit server config with a graphical interface instead of manual file edits
• Categorized browsing and search filtering for faster navigation
• Great for daily tuning; some settings still require a server restart

Player Management

• Online player status overview
• Whitelist management
• Ban management
• OP permission management
• Common actions like kicking players

Plugin System

Lua script-based plugin extension mechanism:

• Plugins can register custom UI components and pages
• Context menu extensions
• Plugin permission management panel
• Sandboxed plugin runtime
• Plugin install / enable / disable / delete workflow
• Plugin market entry with improved failure feedback and state retention

Theme System

• 5 built-in themes: Default, Midnight, Ocean, Rose, Sunset
• Dark/light mode toggle
• Acrylic/frosted glass effect (Windows)
• Complete CSS Variables design token system with runtime switching

Multi-language Support

10 built-in languages:

• 简体中文, 繁體中文
• English, 日本語, 한국어
• Français, Deutsch, Español
• Русский, Tiếng Việt
• Runtime language switching without app restart

Java Management

• Auto-detect Java runtimes installed on the system
• Built-in Java downloader for one-click installation
• Manual Java path selection with validation support
• Expanded scan paths for common install locations to reduce missed detections

Mod Management

• View installed mod/plugin files under the server directory
• Helpful for conflict checks, duplicate cleanup, and version inspection
• Focused on local management for now; online search and one-click install are still evolving

Server Creation

• Guided workflow to lower setup friction for new servers
• Supports jar / bat / sh startup modes
• Supports importing existing servers or startup files
• Smart startup-mode detection with custom startup command support
• Modpack auto-install is available during the creation flow
• Includes first-launch guidance for EULA-related steps

Safe Shutdown

• Triggers a safe stop flow when Sea Lantern closes
• Reduces the risk of save corruption from abrupt termination

Auto Update

• Check for updates and show current/latest version info
• Includes release-notes preview and download jump
• Arch Linux follows AUR workflow; other platforms follow their own installer flow

System Tray

• Keep server processes running after minimizing to tray
• Quickly restore window or exit from tray actions

Usage Suggestions

• First-time setup: use "Server Creation" to bootstrap, then tune key options in "server.properties Editor"
• Daily operations: rely on "Console" and "Player Management" for frequent actions instead of repetitive manual commands
• Long-running hosting: combine "System Tray" and "Safe Shutdown" to reduce accidental interruption risk

Scope Notes

• Behavior can differ by server core and operating system; follow page-specific notes when configuring
• Auto update is "version check + download guidance"; installation replacement is still user-confirmed
