Capture a webpage, preserve its contents and create an independently verifiable timestamped package—without uploading the webpage itself. Capture it. Seal it. Prove it. Beaver Page Proof creates verifiable records of online content using a focused, private web browser and OpenTimestamps. Open any webpage, sign in if necessary and create a complete Page Proof. The app captures the webpage and packages its screenshot, PDF report, web archive, URL and metadata into a standard ZIP archive. The completed archive is timestamped through the public OpenTimestamps network. Only a cryptographic hash is submitted—the webpage, screenshots, login information and archive remain on your Mac. A complete evidence package Each Page Proof includes: Full-page screenshot Readable PDF report Original URL and page title Capture date and technical metadata Web archive for later inspection SHA-256 integrity information Independent OpenTimestamps proof Clear verification instructions Independently verifiable After the evidence archive has been created, Beaver Page Proof waits for confirmation through OpenTimestamps and the Bitcoin blockchain. The final package contains: The original evidence ZIP Its matching OpenTimestamps proof A readable timestamp report Step-by-step verification instructions Anyone receiving the package can verify it independently at OpenTimestamps.org. No Beaver account or paid verification software is required. Works with private pages Because the webpage is opened directly inside Beaver Page Proof, you can also document content that requires a login, such as customer portals, orders, account pages and personalized offers. Support depends on the website. Some passkey, third-party OAuth or enterprise single sign-on systems may not permit authentication inside embedded browsers. Designed for privacy No Beaver account No analytics or tracking No webpage uploads No screenshots stored in the cloud No subscription Only a cryptographic commitment is submitted to OpenTimestamps Important Beaver Page Proof verifies the integrity and timestamp of the generated archive. It does not certify that statements displayed on a webpage are factually correct and does not provide legal advice or guarantee acceptance as evidence in a particular proceeding. Timestamping is provided through independent public OpenTimestamps calendars. Availability and confirmation time are outside the developer’s control. - = - = - = - = - = - = - = - = - = - = - = - = - = - = - = - = - = - = - Part of The Beaver Tools — a collection of focused Mac utilities.
