This is the public wiki for the Heritrix archival crawler project.
Heritrix is the Internet Archive's open-source, extensible, web-scale, archival-quality web crawler project.
Heritrix (sometimes spelled heretrix, or misspelled or mis-said as heratrix/heritix/heretix/heratix) is an archaic word for heiress (woman who inherits). Since our crawler seeks to collect and preserve the digital artifacts of our culture for the benefit of future researchers and generations, this name seemed apt.
All topical contributions to this wiki (corrections, proposals for new features, new FAQ items, etc.) are welcome! Register using the link near the top-right corner of this page.
Heritrix is designed to respect the robots.txt exclusion directives† and META nofollow tags, and collect material at a measured, adaptive pace unlikely to disrupt normal website activity.
If you notice our crawler behaving poorly – The Internet Archive uses archive.org_bot as User Agent when crawling – please send us email at archive-crawler-agent@lists.sourceforge.net.
(If you see a different User-Agent in your logs that still says 'heritrix', it may be someone else using this open-source software. In such a case, even if we can't directly change how your site is crawled, we are happy to help you interpret your logs and identify, contact, or block the source of any troublesome crawling.)
† The newer wildcard extension to robots.txt is not yet supported (feature request).

Heritrix release 1.14.4 is now available at Sourceforge: https://sourceforge.net/projects/archive-crawler/files/

Project bug/issue tracking For Heritrix is in a JIRA-based system: http://webteam.archive.org/jira/browse/HER
If you register to report/comment on JIRA issues, that same login will work for wiki edits and comments, and we welcome people to 'be bold' in adding/updating/improving project wiki pages.
For starting with Heritrix3, the Heritrix 3.0 and 3.1 User Guide provides getting-started and reference information.
Javadoc API documentation, which also serves as the canonical documentation for crawl operators on configuration of built-in modules:
The 1.x-based Heritrix User Manual covers getting started with Heritrix and many advanced topics. This User Manual is generally focused on Heritrix 1.X versions, not fully updated for 1.12/1.14 or the larger changes in 2.0/3.0, but provides a reasonable basis for getting started with Heritrix, especially 1.14.4.
There is a FAQ from the 1.x era: http://archive-crawler.sourceforge.net/faq.html
The Knowledge Base contains topical articles documenting parts of the crawler and common problems or usage scenarios.
For developers, the 1.x-based Heritrix Developer Manual provides a guide to extending and customizing Heritrix code for your own purposes, though of course the source code itself, which is fairly well-commented, is the best guide.
For future documentation improvements, we have a [Documentation Wishlist](Documentation Wishlist).
An Introduction to Heritrix provides more detailed information on the structure and design of Heritrix.
Some very-old info can still be gleaned from the old wiki (http://web.archive.org/web/*/http://crawler.archive.org/cgi-bin/wiki.pl?HomePage).
