Launcher

What the launcher does

The Bedrock Cosmos Launcher is a Windows application that acts as a local proxy to add custom capes and skin packs to Minecraft Bedrock Edition. The README is short and says more documentation is coming soon, but the core function is clear: it intercepts and modifies the traffic between the game and Mojang's servers so that cosmetic items not normally available can be presented to the client. The project homepage is bedrock-cosmos.app, and the launcher is positioned as a tool for players who want to personalize their character appearance beyond the official catalog. Because it works as a proxy rather than by modifying game files directly, the approach keeps the game installation itself untouched and routes cosmetic data through the local interception layer.

Dependencies and how it is built

The launcher is written in C sharp and depends on several NuGet packages. AutoUpdater NET handles launcher updates, Discord Rich Presence C sharp displays a Discord activity for the launcher, and System.Text.Json handles response queries and other JSON data. Titanium Web Proxy allows the decryption and modification of web traffic, and the README notes that a reference is included in the source code to fix an exception thrown while debugging with the latest NuGet package. A reference to System.IO.Compression.FileSystem is used for extracting the contents of zip files, which is how downloaded assets are unpacked. The dependency list is the main technical content in the README, and it tells a clear story: the proxy capability comes from Titanium Web Proxy, the presentation hook comes from Discord Rich Presence, and updates are managed by AutoUpdater NET.

Status and licensing

The project is early in its public documentation, with the README promising more details later and currently focusing on the dependency list and the high level description. The repository carries 29 stars and 4 forks with no open issues at the time of this writing, the default branch is main, and the license is MIT. The practical takeaway is that this is a Windows only, C sharp based cosmetic loader for Minecraft Bedrock Edition that works through local proxy interception, and anyone evaluating it should watch the project's documentation for the promised setup and usage details. As with any tool that modifies game traffic, users should understand their game platform's terms before using it.

Editorial conclusion

The Bedrock Cosmos Launcher is an MIT licensed C sharp Windows tool on the main branch with 29 stars that uses Titanium Web Proxy to inject custom capes and skins into Minecraft Bedrock Edition, with more documentation promised by the maintainer.
