• It's fast, designed from the ground and up with speed-optimization in mind.
• Scriptable through Javascript with E4X
• User-defined filetype filtering (according to MIME type, file extension or UMEX expression)
• Multi-threaded
• Highly configurable from command line
• Extensible module system, supporting custom data parsers, filters and protocol handlers.
• MySQL support through the Javascript-MySQL binding (lmm_mysql).
• Simple yet powerful filtering of URLs through UMEX.
• Automated downloading
• Support for automatic cookie handling when running over HTTP
• Robots Exclusion Standard
• Reliable, fault-tolerant networking, redirect-loop detection and some spider trap detection
• Parser chaining, share data easily between C and javascript parsers
• Unix-friendly interface, piping in and out data for parsing and crawling
• HTML to XML/XHTML conversion
• Portable, tested with success on 32-bit/64-bit Linux 2.6, 32-bit/64-bit FreeBSD 6.x/7.0 and Mac OS X. Should work on almost any Unix-like OS, partial support for Windows. Old versions of Methabot have full support for Windows.
