The Archive.org project (Internet Archive Wayback Machine), which has been storing website changes since 1996, is a collaborative initiative with the developers of the Brave web browser, resulting in a feature that checks for the existence of a page in archive.org when attempting to open a non-existent or unavailable page in Brave, providing a suggestion to view the archived copy if found. This innovation was introduced in Brave Browser version 1.4.95. For , and it, extensions with similar functionality have been prepared.
The check occurs when the site returns error codes 404, 408, 410, 451, 500, 502, 503, 504, 509, 520, 521, 523, 524, 525, and 526. Notably, after this capability was implemented, some challenges arose: Web developers issues while testing their 404 handlers on a local system (instead of a server response, a placeholder for the Wayback Machine is displayed). Security researchers
identified a potential information leak while actively using Tor (calls to the API brave-api.archive.org are made not through Tor). The suggestion to view the archived page when opening sites that use CloudFlare's DDoS protection service.
Let us remind you that the web browser is developed under the guidance of Brendan Eich, the creator of JavaScript and former head of Mozilla. The browser is built on the Chromium engine, focuses on protecting user privacy, includes an integrated ad-blocking engine, can operate through Tor, and provides built-in support for HTTPS Everywhere, IPFS, and WebTorrent, an alternative to banners for funding publishers based on subscriptions. The project code is licensed under the MPLv2 license.
