kage

kage saves websites that actually still work offline. Hit "save page" in a browser and half the time you get a broken mess later, because the JavaScript phones home to servers that are gone. kage renders the page in headless Chrome, grabs the finished result, strips every script, and pulls the CSS, images, and fonts down to disk. What's left is a static copy that doesn't rot. Go, MIT licensed, free.

It's a command-line tool that does more than dump a folder. It can output a browsable mirror, a compressed ZIM archive, or a self-contained executable you can hand to someone, and it'll serve the clone locally so you can preview it. It respects robots.txt and sitemaps while crawling, and the output is deterministic, so the same site produces a byte-identical archive you can checksum. That's a thoughtful detail most scrapers skip.

Useful for archivists, researchers, or anyone who wants a permanent, readable copy of something before it disappears or changes. It's a single-purpose CLI, free for everyone, with nothing to buy. Run it when you need a snapshot you can trust to still open in five years.

The catch is what it removes. Stripping JavaScript is the whole point, but it also means anything that genuinely needs scripts to function, a web app, an interactive tool, won't survive the trip. kage preserves pages you read, not apps you use. Know which one you're archiving before you run it.
