Internet Archive: WayBack Machine compared with Perma.cc and Webrecorder
Internet Archive: WayBack Machine	Perma.cc	Webrecorder
Purpose and scope: A public archive of the web that lets you enter a URL, pick a date and browse earlier versions of a page. Its Save Page Now function also captures a page as it appears at that moment, so it can be cited later.	Purpose and scope: A service from the Harvard Library Innovation Lab that turns a cited URL into a permanent link. The reader reaches a page offering both the original source and the archived copy, with the creation date.	Purpose and scope: A set of tools rather than one service: ArchiveWeb.page records pages while you browse, ReplayWeb.page plays archives back, and Browsertrix crawls whole sites automatically.
Capture method and limits: Captures come from web crawls. Standard HTML archives well, but pages relying on forms, JavaScript or live interaction lose that functionality. Password-protected pages are excluded, and robots exclusions or owner requests can block a site.	Capture method and limits: The user submits a URL and Perma.cc downloads the content.	Capture method and limits: Browsertrix crawls in real browsers, so JavaScript-loaded content can be captured, and browser profiles give access to logged-in pages without exposing a password. Crawls can be scheduled and compared with the live site.
Formats and programmatic access: Stored files include WARC. A Wayback availability JSON API returns the closest snapshot to a date, and a CDX server API supports filtering and analysis of capture data.	Formats and programmatic access: Archives can be downloaded as WARC or WACZ files through a REST API at api.perma.cc/v1. Most endpoints need an API key, and ReplayWeb.page is recommended for viewing them.	Formats and programmatic access: Archives are exported as WACZ, which can be unzipped to obtain the WARC files. Browsertrix signs WACZ outputs digitally and deduplicates content across crawls.
	Openness and licence: The Perma code is public on GitHub under a dual MIT and GPL version 3 licence.	Openness and licence: ArchiveWeb.page is published under AGPL-3.0. Browsertrix can be self-hosted, and professional support is sold for self-hosted deployments.
Cost and access: Free to use at archive.org, with the collections searchable through the Wayback Machine.	Cost and access: Academic institutions and courts can register for free and provide accounts to their users. Other users take a paid subscription or buy batches of links. A subscription limits only new links created each month, not access to existing ones.	Cost and access: ArchiveWeb.page is free. Browsertrix is a paid subscription (Starter after a 7-day trial, Standard and Plus), with custom quotes for Pro and Enterprise.
