In their own words
Alternate Current
Alternate Current is a free, MIT-licensed mod for Minecraft: Java Edition that changes how redstone dust calculates power and updates blocks. It builds networks from connected wires and spreads power from wires receiving power outside a network. The project says this makes updates deterministic and less dependent on location, while retaining high Vanilla parity.
The mod focuses on reducing server work. Its README says redstone dust contributes up to 20 times less MSPT with Alternate Current, and that network-level optimizations can reduce updates by up to 20%. Listed Minecraft versions include 1.14 through 1.21.11, with some specific releases also listed; supported versions and loaders vary by release. Modrinth lists Fabric, Forge, NeoForge, Ornithe and Quilt, and server-side and singleplayer environments. The project links to its source repository, issue reporting and a Discord server. Its GitHub repository has no detected security policy and no published security advisories.
FerriteCore
FerriteCore is a free, MIT-licensed coremod for Minecraft: Java Edition that targets RAM use. It reduces memory associated with block states, models, predicates, strings, voxel shapes and baked quads through a set of documented optimizations. Examples include replacing block-state neighbor tables with FastMaps, caching multipart model predicates, deduplicating model instances and reducing baked-quad memory. The project reports that individual techniques saved hundreds of megabytes in cited tests; one pack example showed post-garbage-collection memory moving from roughly 3.1 GB to 1.1–1.2 GB on the title screen. Several optimizations have no CPU impact during play, while some add load-time CPU cost. ThreadingDetector optimization is disabled by default because it may very rarely cause race conditions. FerriteCore supports Fabric, Forge, NeoForge and Quilt and is listed for Minecraft Java Edition versions 1.16.5 through 26.3, depending on loader builds. It is marked for both client and server use, and the maintainer recommends installing it on both because some optimizations apply server-side. Versions before 1.16 are not supported for backporting.
