MeshCore

MeshCore is an open-source software publisher focused on decentralized radio communications, distributing its work through the project's website at meshcore.io. The publisher's catalog centers on a single flagship product, MeshCore, a lightweight hybrid routing mesh protocol designed for packet radios. The software enables low-cost, low-power radio devices to form self-organizing mesh networks in which messages are relayed from node to node until they reach their destination, allowing communication across distances far greater than any single radio link could achieve on its own. Because the protocol operates independently of cellular carriers, internet service providers, and centralized infrastructure, it is well suited to off-grid messaging, emergency and disaster communications when conventional networks are unavailable, outdoor recreation such as hiking and expeditions, and community or amateur radio projects. Typical deployments involve companion radios, repeaters, and room-server nodes running on affordable microcontroller-based LoRa hardware, with users exchanging text messages and location data through connected mobile or desktop applications. The hybrid routing approach is intended to balance efficient delivery with the constraints of bandwidth-limited radio links, keeping overhead low so that even modest devices can participate in the network. As a lightweight protocol, MeshCore targets hobbyists, makers, emergency preparedness groups, and developers who want to build resilient, infrastructure-independent communication systems using inexpensive off-the-shelf hardware. With one package currently listed, the publisher's range is compact but specialized, concentrating on the protocol itself and the firmware and tooling needed to bring compatible devices onto a mesh network. Users interested in the technology can obtain the software, documentation, and setup guidance directly from the project website.
