Offline maps
State map packs and local tile serving for navigation when cloud maps are not reachable.

For what you cannot look up later
A long outage does not wait for coverage to return. The beta is organized around what you need to find, decide and execute when there is no margin left.
02
Local library
Curated ZIM references and field guides with local search, no telemetry and clear source boundaries.
03
Mesh comms
USB Meshtastic bridge for local node awareness, messaging and emergency relay workflows.
04
Inventory
Household supplies, expiry tracking, starter seeds and recovery planning for repeated use.
05
Family continuity
Kids learning, simple checklists and routines that still work during long outages.
06
Controlled beta
Private keys, activation limits and admin controls for distributing test builds responsibly.
Prepared before failure, useful during failure
The website only controls beta access. The product is the offline Windows experience that remains usable when the connection is no longer helping.
Current beta UI
The screenshot is generated from the local app, so it reflects the active walkthrough and private beta shell.
Offline-first posture
The top status bar highlights the core promise: no cloud, no telemetry, local data and blackout-friendly workflows.
Designed for the worst moment
The beta prioritizes fast access, clear paths and available content before the problem begins.

These areas increase real resilience, but they should not be sold as finished until they are ready for testers.
Tester portal
A place for each tester to view license status, downloads and activation history.
Guided updates
Beta channel with release notes, hashes and recommended builds.
Expanded packs
More offline content by capability: radio, repairs, power and family readiness.
Tester access
Private beta access, so you can test it before you need it.
GridDown OS is currently distributed through private license keys. Testers receive an installer and a limited-activation key to validate the system under normal conditions, before a real outage turns preparedness into urgency.
