About The Last Light
A complete, fully-offline survival library — built for the moment the grid isn't there.
The Last Light Survival Guide exists on one principle: knowledge should keep working when everything else stops. No internet, no accounts, no company that can switch it off. Just a folder of plain files you can keep on a USB stick, a phone, or a bunker's laptop — and reach when you need it most.
How it's built
The whole thing is shaped by one question: will this still work when the infrastructure is gone?
Offline-first, by design
Pure static HTML, CSS and JavaScript — no build step, no framework, no server. It opens straight from a folder and runs with zero internet on anything from a phone to a 15-year-old laptop to a Raspberry Pi.
Zero dependencies
Nothing to install, nothing to update, nothing that can rot. The guide is plain files you can read, copy, and keep — the same way you'd keep a paper book.
Private by default
No accounts, no ads, no tracking, no analytics that phone home. What you read is nobody's business. Nothing leaves your device.
The AI runs on your machine
Bunker Bot's AI runs on your own computer, not in the cloud — no internet needed. It answers using the books bundled in this guide, and always shows exactly which book and page it got the answer from, so you can check it yourself.
Resilient
A SHA-256 manifest lets you verify your copy hasn't been tampered with, and torrent / IPFS options mean it survives takedowns. Copy it as many times as you like.
Free and open
Free to download, free to share, and licensed CC BY-SA — mirror it, fork it, rehost it. It belongs to everyone who keeps a copy.
The content is broad and AI-assisted, and the medical material has not yet been reviewed by a licensed clinician. It's a reference, not professional advice — verify anything critical, and seek qualified help whenever it's available. The inline citations are there so you can check every claim.
Get involved
This is a community resource. The most valuable help right now is expert review — if you're a clinician, ham, vet, engineer or experienced homesteader and can correct a section, please do. And mirror it, share it, keep it alive.
