Arachnophilia is a source code editor written in Java by Paul Lutus. It is the successor to another HTML editor, WebThing. The name Arachnophilia comes from the term meaning "love of spiders", a metaphor for the task of building on the World Wide Web.

Arachnophilia is free and open-source software subject to the terms of the GNU General Public License.


Once written as a Windows application, the program was rewritten by Lutus in Java as part of his boycott against Microsoft and its product activation features for Windows XP. Arachnophilia requires the Java 2 runtime environment, release 1.5 or later.

The program was licensed as Careware software, then as LGPL-2.1-or-later in 2011, and now as GPL-2.0-or-later since 2018 with the source available on the website.


The program can import and convert to HTML various RTF documents, tables and outlines from any Windows 95 (and above) compliant application. The output of the code can be previewed in up to six different web browsers. It supports CGI, frames and other languages beside HTML, for instance PHP, Perl, C++, Java, and JavaScript development.

Other features include:

  • Multiple-document interface
  • User-customizable toolbars
  • Full drag and drop support
  • Global search and replace
  • Built-in FTP client
  • Automatic uploading of files
  • User-defined templates
  • User-defined macros
  • User-defined key bindings
