Link Rot Prevention
The web forgets. You don't have to.
Save sources permanently, not just as bookmarks.
Studies estimate over 50% of links in academic papers are broken within a decade. Wikipedia citations die. News articles disappear behind paywalls. Backdrop permanently archives any URL in four formats so your work is never invalidated by a 404.
Four-format capture
HTML, PDF, screenshot, and readable text archived simultaneously. Multiple formats mean multiple recovery options.
Instant archiving
One-click capture via browser extension. No copy-pasting URLs into separate tools.
Original URL preserved
The source URL and capture date are stored with every archive, maintaining clear provenance.
Permanent storage
Archives don't expire. A page saved today is available years from now.
Searchable full text
Every word of every archived page is indexed for full-text search.
Offline access
Archived pages are available even when the original source goes down.
How it works
Find a page worth keeping
Any URL — article, study, dataset, policy document, product page, or social post.
Archive with one click
The browser extension captures all four formats silently in the background.
Reference the archive, not just the URL
Cite the Backdrop archive alongside the original URL. If the original dies, the archive lives.
Find it years later
Full-text search surfaces any archived page by content, not just by URL or title.
“I stopped trusting URLs years ago. Now I archive anything I might ever need to cite. My thesis bibliography is 100% intact three years after submission. Not one dead link.”
