Endweave

Seamlessly interweaving Bedrock protocol versions.

An Endstone plugin that lets Bedrock clients connect to servers with different protocol versions by rewriting packets at the network layer. Inspired by ViaVersion.

Supported Versions

Endweave translates between any two of these:

26.45 puts the same bytes on the wire as 26.40-26.44 under a different number, so Endweave carries a client on either onto a server on the other by writing the server's number into the handshake, and translates nothing.

Not translated

These versions are known to Endweave but not carried by the 0.5.0 engine:

Endweave up to 0.4.3 translated 1.21.120 through 26.20, and 26.30 was never translated by any release. A client on one of these can still join a server speaking the same protocol; it just gets nothing from Endweave.

Quick Start

1. Open the latest release and download the wheel that matches your server. Several are attached, one per platform and Python version:
   • win_amd64 for Windows, manylinux_2_28_x86_64 for Linux on glibc 2.28 or newer.
   • cp310 for Python 3.10, cp311 for 3.11, cp312-abi3 for 3.12 and later.
2. Drop it in your server's plugins/ folder
3. Restart the server

Endstone installs the file you drop in, so a wheel built for another platform or Python version is refused and the plugin does not load. The install also fetches a few dependencies from PyPI, so the server needs network access the first time it starts with Endweave in plugins/.

Players on newer clients will connect transparently. No additional configuration needed.

How It Works

Endweave handles protocol differences between Minecraft versions, allowing players to join servers on different protocol versions. Whether a client is newer or older than the server, packets are translated in real time. Only fields that actually changed get rewritten, and players already on the server's version go through zero extra processing. A packet the other version has no counterpart for is dropped rather than forwarded, so neither end is handed something it cannot read.

Since 0.5.0 the translation runs in a C++ engine compiled from bedrock-protocol rather than in Python.
