HttpInfoServer
HttpInfoServer starts a local HTTP and WebSocket server inside the game, so in-game player information can be read from the player's own computer.
What it does
When the game starts, the mod's entry point runs and creates WebSocket instances. A local server then serves player information taken from the running game, which lets other programs on the same computer read it while the game is open. The server does not need to reach any outside host.
Collection is handled by a dedicated class, InfoCollector, whose genJson function gathers the data and converts it into a JSON string. The WebSocket server needs that method to produce its responses, so the two parts work as a pair. The code has been cleaned up, and the project is open source under the Apache License 2.0.
The mod is Fabric-only and is published for 1.20.4 and 1.20.6, with 1.20.6 as the latest file, dated 2024-05-28. It is client-side only, so the server does not need it and players install it on their own computer. Its author is dadencukillia, and the source code, issue tracker and wiki are public.
Key features
Local HTTP API
A small server runs on the player's computer and answers requests with in-game player information.
WebSocket connections
WebSocket instances are created at startup, so external tools can keep a live connection to the game.
JSON player data
The collected information is formatted as a JSON string that other programs can parse without extra conversion.
Startup entry point
The mod's initializer starts the server as soon as Minecraft loads, with no in-game setup needed.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
Use cases
Companion overlays
Tools that show extra information beside the game can read the player data from the local server while playing.
Personal stat tracking
A script on the same computer can log player details over time through the JSON output.
Who it’s for: Players who run helper tools on their own computer, and developers who want a local data feed from a Fabric client without adding a server-side component.
How it compares
ws2tcp is Fabric-only and client-side only, for 1.21.4, and is open source under the Apache License 2.0. AmbleKit covers both client and server for 1.20.1 – 1.20.6 on Fabric and Forge and is open source under the MIT License. HttpInfoServer shares the same client-side environment as ws2tcp but targets the 1.20.4 and 1.20.6 builds.
