• One-click installation from CurseForge and Modrinth. Users can browse any mod or modpack directly within the launcher interface. When a pack is selected, Proxima downloads the files, verifies data integrity, and places the mods into the appropriate folder without any additional manual intervention.
• Automatic dependency management. Many mods require specific libraries or APIs such as Fabric, Forge, or Quilt. Proxima identifies these dependencies during installation, downloads them, and configures them automatically so the mod runs without loading errors.
• Isolated game profiles. Each Minecraft instance is created in a separate directory with its own configuration folders, mods, and worlds. This prevents conflicts between different modpacks and allows profile switching without losing progress in any world.
• Automatic mod and modpack updates. The launcher periodically checks for new versions published on CurseForge and Modrinth. When a modpack receives an update, Proxima downloads the changes and replaces outdated files without requiring a manual reinstallation of the entire pack.
• Automatic installation of the correct Java version. Minecraft requires specific Java versions depending on the game version. Proxima detects which Java the selected profile needs, downloads the appropriate runtime, and executes it without modifying the system's global Java installation.
• Skin support for non-premium accounts. Players without an official Minecraft account can upload custom skins. The launcher injects the selected skin into the game through runtime modifications, allowing other players to see the skin on multiplayer servers.
• Crash analysis with artificial intelligence. When Minecraft closes unexpectedly, it generates a crash log. Proxima processes these logs, extracts the most relevant error lines, and compares them against a database of known issues. The system displays an explanation of the possible error source to the user.
• Lightweight interface and fast startup time. The launcher executable occupies less than 30 MB and is optimized to consume no resources during Minecraft gameplay. The main window appears in less than one second after double-clicking the shortcut.
• Silent launcher updates. Proxima updates itself in the background when the user starts the program. It downloads security patches and new features without showing dialog boxes or asking for confirmation.
• Quick switching between Minecraft versions. The profile selector allows choosing any official game release, from the oldest versions to the latest snapshots. The launcher downloads the necessary client files and automatically configures the appropriate startup arguments.
• Support for custom JVM arguments. Advanced users can add specific parameters for the Java virtual machine, such as RAM allocation, optimization flags, or alternative paths for native libraries.
• Microsoft account integration. The launcher uses the official Microsoft authentication flow for login. Access tokens renew automatically without requiring password re-entry each session.

Proxima Launcher development began in 2023 by an independent European team specializing in gaming tools. The application is primarily written in C# and uses .NET 6 as its core framework. The graphical interface was implemented with Windows Presentation Foundation (WPF) to ensure smooth performance on Windows systems. Network components interacting with CurseForge and Modrinth APIs are developed in C# with asynchronous calls. Skin injection functionality was implemented through in-memory patches written in native C++ to avoid anticheat detection.
