What it is. Why it exists.
ChronoKeep is a Manifest V3 browser extension that silently submits every web page you visit to the Internet Archive Wayback Machine. The moment a page finishes loading, a background service worker fires a save request to https://web.archive.org/save/. The page gets a permanent, publicly-accessible snapshot — without any action from you.
Pages disappear. Articles get paywalled. Documentation moves. Link rot is real. ChronoKeep ensures that everything you read has a permanent snapshot — so you, or anyone with the URL, can always find it again.
Your ignore list, on/off toggle, and archive delay sync across all your signed-in Chrome and Edge instances via chrome.storage.sync. This uses the browser's own sync mechanism — no account we manage, no server we run.
ChronoKeep is fully open source under the MIT License. The source is on GitHub. Contributions, bug reports, and feature requests are welcome.
The extension has no server, no database, no analytics, and no accounts. All local state lives in chrome.storage. The only network requests it makes are save requests to web.archive.org.
