What LibreMesh is
LibreMesh is a free, modular framework for creating OpenWrt-based firmware for wireless mesh nodes. It is intended for people building decentralized, community-run networks. Its codebase provides defaults for Babel, B.A.T.M.A.N. advanced, BMX7, and OLSR; the default network design combines BATMAN-adv at layer 2 with Babel at layer 3 to support roaming and network segmentation. The project describes a default flavor that can work without manual configuration and aims to make setup and management accessible through a web interface usable on smartphones. A customized build can be requested through the online ImageBuilder selector, or users can build LibreMesh on a host or use archived precompiled releases. The project recommends routers with at least 16 MB flash and 128 MB RAM, though installation is possible on 8/64 MB devices. Configuration files can be managed with OpenWrt UCI or edited manually. The software may be used, copied, modified, and distributed under the AGPL license. The project advises customizing builds to preserve firmware space and device RAM, and warns against upgrading packages directly.
