On the roadmap: Code next to data (0.3), Mixin (0.5)

In the author's words

Simple mod with helpful data attaching and networking utilities including attaching data to entities, chunks, players, and worlds with low boilerplate code. Its own system built from the ground up for multiloader support.

Scan

Scanned on 4 November 2026 against Kiln 0.2.0, file dataanchor-fabric-26.3-6.0.0.2.jar. The scan reads the mod's classes; it does not run them.
