Heritrix: Open-Source Web Crawler
An open-source, extensible web crawler project built on Apache stack for archiving periodic captures of content from the web and large intranets.
What is Heritrix?
Heritrix is an open-source web crawler software project that was originally developed by the Internet Archive. It is designed to systematically browse and archive web pages by recursively following hyperlinks and storing the content in the WARC file format.
Some key features of Heritrix include:
- Extensible and modular architecture based on Apache standards to support customization
- Respects robots.txt and other directives to avoid overloading servers
- Supports metadata extraction, post-processing of archived data, recovery from errors
- Distributed architecture for high performance, scalability and robustness
- Advanced configuration for in-depth crawling jobs targeting specific parts of websites
Heritrix is well-suited for building specialty search engine indexes, archiving online content for preservation purposes, and offline browsing of websites. Its focused crawling features allow users to customize crawl scopes and avoid unrelated content.
While Heritrix excels at archival-quality crawls, it has higher overhead than some other crawler software. It prioritizes quality, completeness and politeness over crawling speed. Heritrix is typically run on powerful servers and can handle complex, large-scale web crawling projects.
