Nexo Client
by Lokifisch
Nexo Client is a Fabric mod for Minecraft 26.1.2 that pairs with a rebranded install and launch app as a personal client project.
What it does
The mod is the Fabric half of a personal Minecraft client project. Its author describes it as a small client with new features, and the companion app replaces a monolithic custom launcher with a rebranded install and launch tool. A built jar lands in build/libs/, and the instance's mods folder needs it next to Fabric API.
Rather than rebuilding the underlying protocols from scratch, the mod takes over functioning code from two MIT-licensed open-source projects. It draws on a LAN tunnel relay client from vgskye's e4mc project, a Microsoft OAuth sign-in flow from axieum's authme, and an own-nametag visibility technique from Fix85's SelfNametag. The UI uses the bundled Noto Sans font under the SIL Open Font License. Attribution and the exact ported code are listed in THIRD-PARTY-NOTICES.md.
Nexo Client runs on Fabric Loader 0.19.3 or newer and Java 25 or newer. Only the client needs it, so servers run without it. It is released under the MIT License and is open source. Files exist for 26.1.2 and 26.2, with 0.1.0 for 26.2 as the latest Fabric file, published on 2026-07-14 on the alpha channel.
