ZimIt compared with HTTrack, SingleFile and WebCopy| ZimIt (.zim archive maker) | HTTrack | SingleFile | WebCopy |
|---|
| Output format: A single ZIM file, built by running Browsertrix Crawler to produce WARC files and converting them with warc2zim. The ZIM is meant to be read in a Kiwix reader. | Output format: A local folder that mirrors the site structure, with relative links so it can be browsed offline. Version 3.50 adds WARC output. | Output format: One HTML file per saved page. An optional self-extracting ZIP is also offered, and MHTML and other formats appear in the maintainer comparison. | Output format: A local copy of the site: pages, images and style sheets, with links rewritten to point to the local files. |
| Handling of dynamic content: The crawl runs in an automated browser, and options such as --waitUntil control page loading. | Handling of dynamic content: The FAQ warns that intensive Java and JavaScript sites may be incomplete, and that generated file names are not always recognized. It follows robots.txt by default. | Handling of dynamic content: The page is saved from the browser as displayed, as an extension or a command-line tool. It targets single pages, not a recursive crawl of a whole site. | Handling of dynamic content: There is no JavaScript parsing, so links generated by scripts may be missed and the copy can be incomplete. It stores what the server returns, not source code. |

The same engine runs locally from the Docker image ghcr.io/openzim/zimit, with options such as --pageLimit and --workers. | Licence and openness: Free software under the GNU GPL. | Licence and openness: AGPL-3.0, with third-party code under MIT.
