Current statusOnline (formerly is an archive site which stores snapshots of web pages. [2] It retrieves one page at a time similar to WebCite, smaller than 50MB each, but with support for modern ("Web 2.0") sites such as Google Maps and Twitter.

In web archiving, an archive site is a website that stores information on webpages from the past for anyone to view.

WebCite is an on-demand archive site, designed to digitally preserve scientific and educationally important material on the web by making snapshots of Internet contents as they existed at the time when a blogger, or a scholar or a Wikipedia editor cited or quoted from it. The preservation service enables verifiability of claims supported by the cited sources even when the original web pages are being revised, removed, or disappear for other reasons, an effect known as link rot.

Web 2.0 World Wide Web sites that use technology beyond the static pages of earlier Web sites

Web 2.0 refers to websites that emphasize user-generated content, ease of use, participatory culture and interoperability for end users.

Contents uses headless browsing to record what embedded resources need to be captured to provide a high-quality memento, and creates a PNG image to provide a static and non-interactive visualization of the representation. [3]

Portable Network Graphics Family of lossless compression file formats for image files

Portable Network Graphics is a raster-graphics file-format that supports lossless data compression. PNG was developed as an improved, non-patented replacement for Graphics Interchange Format (GIF). can capture individual pages in response to explicit user requests. [4] [5] [6]

Since July 2013, supports the Memento Project application programming interface (API). [7] [8]

An application programming interface (API) is an interface or communication protocol between a client and a server intended to simplify the building of client-side software. It has been described as a “contract” between the client and the server, such that if the client makes a request in a specific format, it will always get a response in a specific format or initiate a defined action.

History was founded in 2012. The site originally branded itself as, but in May 2015, changed the primary mirror to [9] In January 2019, it began to deprecate the domain in favor of the mirror. [10]

Worldwide currently blocks requests from Cloudflare's recursive DNS resolver, [20]

Additionally, since late 2018, has implemented a data cap limitation, presumably to help protect against denial-of-service attacks. Individual users can only archive and/or retrieve approximately 10 to 20 megabytes of data per day. After that limitation is reached, their web server blocks the individual user's IP address by no longer responding.[ citation needed ]

Features records only text and images, excluding video, xml, rtf, spreadsheet (xls or ods) and other non-static content. It keeps track of the history of snapshots saved, returning to the user a request for confirmation before adding a new snapshot of an already saved Internet address. [21]

Web pages cannot be duplicated from to as second-level backup, as places a exclusion for Wayback Machine [22] and don't save its snapshots in WARC format. The reverse - from to - is possible, [23] but the copy usually takes more time than a direct capture. Some web sites get deleted from Internet Archive's listings retroactively or blocked from being saved due to their robots.txt file, but does not use this.

The research toolbar enables advanced keywords operators, using * as the wildcard character. A couple of quotation marks address the search to an exact sequence of keywords present in the title or in the body of the webpage, whereas the insite operator restricts it to a specific Internet domain. [24]

Once a web page is archived, it cannot be deleted directly by any Internet user. [25] Nevertheless, regularly controls or deletes web pages saved some days before, without any policy or right of discussion and appeal.[ citation needed ]

While saving a dynamic list, searchbox shows only a result that links the previous and the following section of the list (e.g. 20 links for page). [26] The other web pages saved are filtered, and sometimes may be found by one of their occurrences.

The search feature is backed by Google CustomSearch. If it delivers no results, attempts to utilize Yandex Search.

If a page has already been archived, asks the user to confirm archiving a new revision, instead of immediately archiving it.
