High Desert Institute

LocalNet

A resilient off-grid application stack that gives every outpost a local digital hub for knowledge, AI, and mesh-integrated services.

LocalNet

LocalNet is the resilient, off-grid server stack for the High Desert Institute outposts. It is designed to be a “set-it-and-forget-it” digital hub that empowers regional communities to run their own local tools while integrating seamlessly with the wider mesh network.

As part of the High Desert Institute’s mission to build a foundation for the survival of humanity, LocalNet provides the critical digital infrastructure required for communities to function independently of the traditional internet grid. It is a primary project of the Lorekeepers’ Guild.

Key Features

The Digital Hearth

LocalNet serves as an application server on the local intranet at each outpost, hosting rich services on low-power hardware (e.g., Raspberry Pi, mini PCs, Steam Machines):

  • The Library: Hosting a vast, offline-first repository of survival, technical, and cultural knowledge.
  • The Librarian: A local, privacy-focused LLM (Large Language Model) that acts as an intelligent interface to The Library, answering complex questions without internet access.
  • Pubsub: A lightweight publish-subscribe messaging system to facilitate communication between local applications and services and maintain updated records and library content.
  • Kasm Workspaces: Containerized applications accessible via web browser, providing a variety of tools and environments for users.
  • Collaboration Tools: Local instances of GitLab, Nextcloud, and other collaboration platforms to facilitate teamwork and resource sharing within the community.
  • Knowledge Management Systems: GitLab/Pages for documentation, wikis, and project management.
  • Open WebUI: An open source chat interface for interacting with all the bleeding edge LLMs.
  • Creative AI: Local AI-powered tools for image, code, and music generation.
  • Offline-First Design: All services are designed to function fully offline, ensuring reliability in remote locations.
  • Internet-In-A-Box: Complete local copy of Wikipedia, OpenStreetMaps, and other educational materials.

Mesh Integration (The Cyberpony Express)

LocalNet integrates directly with The Cyberpony Express, HDI’s public Meshtastic-based mesh network.

  • Acts as a bridge between the local high-bandwidth intranet and the low-bandwidth, long-range LoRa mesh.
  • Facilitates secure communication between disparate outposts (e.g., High Ground, Mammoth, Slab City).
  • Hosts the BBS, allowing for asynchronous messaging, bulletin boards, and lightweight applications over the mesh.
  • Records data from regional sensors for things like weather forecasting, environmental monitoring, and resource management.

This project is hosted in a submodule.
