What it is

LibreMesh is a free, modular framework for creating OpenWrt-based firmware for wireless mesh nodes. It is intended for decentralized, community-run networks and is available for self-hosted and web deployment. The code provides defaults for Babel, B.A.T.M.A.N. advanced, BMX7 and OLSR. Its default design combines BATMAN-adv at layer 2 with Babel at layer 3 for roaming and network segmentation. A default flavor is described as working without manual configuration, while the project aims to support setup through a smartphone-usable web interface. Users can request customized builds through the online ImageBuilder, build on a host or use archived precompiled releases. Recommended hardware has at least 16 MB flash and 128 MB RAM, although installation is possible on 8/64 MB routers. Configuration uses OpenWrt UCI or manual editing. The software can be used, copied, modified and distributed under AGPL. The project advises customizing builds to preserve space and RAM and warns against direct package upgrades.
