Eclipse is an integrated development environment (IDE) used in computer programming. It contains a base workspace and an extensible plug-in system for customizing the environment. It is the second-most-popular IDE for Java development, and, until 2016, was the most popular. Eclipse is written mostly in Java and its primary use is for developing Java applications, but it may also be used to develop applications in other programming languages via plug-ins, including Ada, ABAP, C, C++, C#, Clojure, COBOL, D, Erlang, Fortran, Groovy, Haskell, JavaScript, Julia, Lasso, Lua, NATURAL, Perl, PHP, Prolog, Python, R, Ruby, Rust, Scala, and Scheme. It can also be used to develop documents with LaTeX and packages for the software Mathematica. Development environments include the Eclipse Java development tools (JDT) for Java and Scala, Eclipse CDT for C/C++, and Eclipse PDT for PHP, among others.

Tomboy is a free and open-source desktop notetaking app written for Windows, macOS, Linux, and BSD operating systems. Tomboy is part of the GNOME desktop environment. As Ubuntu changed over time and its cloud synchronization software Ubuntu One came and went, Tomboy inspired various forks and clones. Its interface is a word processor with a wiki-like linking system to connect notes together. Words in the note body that match existing note titles become hyperlinks automatically, making it simple to construct a personal wiki. For example, repeated references to favorite artists would be automatically highlighted in notes containing their names. As of version 1.6 (2010), it supports text entries and hyperlinks to the World Wide Web, but not graphic image linking or embedding.
The following tables compare general and technical information for many wiki software packages.
