[[File:Whisker Menu.png|thumb|Whisker Menu - an alternate application launcher for Xfce]]

Applications developed by the Xfce team are based on [[GTK]] and self-developed Xfce libraries. Other than Xfce itself, there are third-party programs which use the Xfce [[Library (computer science)|libraries]].<ref>{{cite web|url=https://goodies.xfce.org/projects/applications/|title=Projects:applications:start &#91;Xfce Goodies&#93;|access-date=24 September 2018|archive-date=6 July 2015|archive-url=https://web.archive.org/web/20150706122903/http://goodies.xfce.org/projects/applications|url-status=live}}</ref>

=== Development framework ===
Xfce provides a development framework which contains the following components:

* exo, an application library for the Xfce desktop environment
* garcon, a Freedesktop.org compliant menu library
* libxfce4ui, a widgets library for the Xfce desktop environment
* libxfce4util, an extension library for Xfce

One of the services provided to applications by the framework is a red banner across the top of the window when the application is running with [[Principle of least privilege|root privileges]], warning the user that they could damage system files.

=== Xfce Panel ===
Xfce Panel is a highly configurable [[taskbar]] with a rich collection of [[Plug-in (computing)|plug-in]]s available for it.<ref>{{cite web |title=panel-plugins [Xfce Goodies] |url=https://goodies.xfce.org/projects/panel-plugins/start |access-date=24 September 2018 |archive-date=24 September 2018 |archive-url=https://web.archive.org/web/20180924145314/https://goodies.xfce.org/projects/panel-plugins/start |url-status=live }}</ref>

Many aspects of the panel and its plug-ins can be configured easily through graphical dialogs, but also by GTK style properties and hidden Xfconf settings.<ref>{{cite web|url=https://docs.xfce.org/xfce/xfce4-panel/preferences|title=xfce:xfce4-panel:preferences [Xfce Docs]|access-date=24 September 2018|archive-date=24 September 2018|archive-url=https://web.archive.org/web/20180924145558/https://docs.xfce.org/xfce/xfce4-panel/preferences|url-status=live}}</ref>

=== Xfce Terminal ===
[[File:XFCE Terminal--February 2007.png|thumb|XFCE Terminal in February 2007]]

A [[terminal emulator]] is provided as part of the Xfce project, but it can be used in other X Window System environments as well. It supports tabs, customizable key bindings, colors, and window sizes. It was designed to replace [[GNOME Terminal]], which depends on the GNOME libraries. Like GNOME Terminal, though, it is based on the VTE library.<ref>{{cite web |url=http://git.xfce.org/apps/xfce4-terminal/tree/README |archive-url=https://archive.today/20130628025459/http://git.xfce.org/apps/xfce4-terminal/tree/README |url-status=dead |archive-date=28 June 2013 |title=xfce4-terminal - A modern terminal emulator |website=Git.xfce.org |access-date=2017-01-09 }}</ref> Xfce Terminal can be configured to offer a varying background color for each tab.<ref>{{cite web|url=https://docs.xfce.org/apps/xfce4-terminal/preferences|access-date=2022-10-11|title=apps:xfce4-terminal:preferences [Xfce Docs]|date=2021-02-26|website=Xfce.org|archive-date=11 January 2023|archive-url=https://web.archive.org/web/20230111041315/https://docs.xfce.org/apps/xfce4-terminal/preferences|url-status=live}}</ref> It can also be used as a drop-down terminal emulator, similar to [[Guake]] or [[Tilda (software)|Tilda]].<ref>{{cite web|url=https://docs.xfce.org/apps/xfce4-terminal/dropdown|access-date=2022-10-11|title=apps:xfce4-terminal:dropdown [Xfce Docs]|date=2022-04-13|website=Xfce.org|archive-date=11 October 2022|archive-url=https://web.archive.org/web/20221011144040/https://docs.xfce.org/apps/xfce4-terminal/dropdown|url-status=live}}</ref>

=== Xfwm ===
Xfwm is a window manager, supporting custom themes.<ref>{{cite web|url=https://wiki.xfce.org/howto/xfwm4_theme|title=howto:xfwm4_theme [Xfce Wiki]|website=wiki.xfce.org|access-date=2019-03-25|archive-date=25 March 2019|archive-url=https://web.archive.org/web/20190325012042/https://wiki.xfce.org/howto/xfwm4_theme|url-status=live}}</ref> Starting with version 4.2, Xfwm integrates its own [[Compositing window manager|compositing manager]].<ref>{{cite web |title=Xfce window manager now includes its own compositing manager |url=http://blog.xfce.org/2004/10/xfce-window-manager-now-includes-its-own-compositing-manager/ |website=Xfce Blog |access-date=20 December 2012 |archive-date=6 February 2012 |archive-url=https://web.archive.org/web/20120206062413/http://blog.xfce.org/2004/10/xfce-window-manager-now-includes-its-own-compositing-manager/ |url-status=dead }}</ref>

=== Catfish ===
A file searching tool, able to perform in-name and in-text matching, as well searching by file type and last modified time. It is also capable of performing [[Search engine indexing|indexing]] by using an [[locate (Unix)|mlocate]] database.<ref>{{cite web|url=https://docs.xfce.org/apps/catfish/start|title=apps:catfish:start [Xfce Docs]|website=docs.xfce.org|access-date=2019-02-23|archive-date=24 February 2019|archive-url=https://web.archive.org/web/20190224173441/https://docs.xfce.org/apps/catfish/start|url-status=live}}</ref>

=== Thunar ===
{{Main|Thunar}}

Thunar is the default file manager for Xfce, replacing Xffm. It resembles GNOME's [[Nautilus (file manager)|Nautilus]], and is designed for speed and a low memory footprint,<ref>{{cite web |url=http://thunar.xfce.org/pwiki/articles/memory_usage |title=Thunar in comparison to Nautilus, ROX, Konqueror and Xffm |website=ThunarWiki |access-date=4 September 2012 |archive-url=https://web.archive.org/web/20120418135505/http://thunar.xfce.org/pwiki/articles/memory_usage |archive-date=18 April 2012}}</ref> as well as being highly customizable through plugins. Xfce also has a lightweight [[Archive file|archive manager]] called Xarchiver, but this is not part of the core Xfce 4.4.0.<ref>{{cite web |title=4.4.0 release status so far |url=http://foo-projects.org/pipermail/xfce4-dev/2007-January/022198.html |website=foo-projects.org |date=20 January 2007 |url-status=dead |archive-url=https://web.archive.org/web/20070928060420/http://foo-projects.org/pipermail/xfce4-dev/2007-January/022198.html |archive-date=28 September 2007 }}</ref> More recently, ''Squeeze'' has been started as an archive manager designed to integrate better into the Xfce desktop, and though no releases have been made since 2008,<ref>{{cite web |title=Squeeze - news |url=http://squeeze.xfce.org/news |work=xfce.org |access-date=13 September 2011 |archive-date=12 May 2012 |archive-url=https://web.archive.org/web/20120512152503/http://squeeze.xfce.org/news/ |url-status=dead }}</ref> the git repository of squeeze has been active and this version is more feature-rich than the last stable release.

=== Orage ===
Starting with version 4.4, Xfcalendar was renamed to ''Orage'' (French for "thunderstorm") and several features were added. Orage has alarms and uses the [[iCalendar]] format, making it compatible with many other calendar applications, e.g. [[vdirsyncer]] to sync via [[CalDAV]].<ref>{{cite web|url=https://github.com/pimutils/vdirsyncer|title=pimutils/vdirsyncer|website=GitHub|date=28 October 2021|access-date=26 August 2017|archive-date=24 October 2017|archive-url=https://web.archive.org/web/20171024005207/https://github.com/pimutils/vdirsyncer|url-status=live}}</ref> It also includes a panel clock plugin and an international clock application capable of simultaneously showing clocks from several different time zones. With Xfce 4.16, and the dropping of GTK2 support for panel plugins, orage was replaced with DateTime plugin.<ref>{{cite web|url=https://forum.xfce.org/viewtopic.php?id=14574|title=Xfce 4.16 Released! / Announcements / Xfce Forums|access-date=17 January 2021|archive-date=11 January 2023|archive-url=https://web.archive.org/web/20230111041318/https://forum.xfce.org/viewtopic.php?id=14574|url-status=live}}</ref><ref>{{cite web|url=https://forum.xfce.org/viewtopic.php?id=14632|title=&#91;SOLVED&#93; Please, where is Orage Panel Clock? / Desktop / Xfce Forums|access-date=17 January 2021|archive-date=16 January 2021|archive-url=https://web.archive.org/web/20210116075555/https://forum.xfce.org/viewtopic.php?id=14632|url-status=live}}</ref>

=== Mousepad ===
{{Main|Mousepad (software)}}
Mousepad is the default [[text editor]] for Xfce in some Linux distributions, including [[Xubuntu]].<ref>{{cite web |url=http://docs.xubuntu.org/1410/appendix-packages.html |title=Xubuntu 14.10 Documentation |website=xubuntu.org |date=29 October 2014 |access-date=28 March 2015 |url-status=dead |archive-url=https://web.archive.org/web/20150402130605/http://docs.xubuntu.org/1410/appendix-packages.html |archive-date=2 April 2015}}</ref> Mousepad aims to be an easy-to-use and fast editor, meant for quickly editing text files, not a software development environment or an editor with a large plugin ecosystem. It does offer tabbed files, syntax highlighting, parentheses matching and indentation features commonly found in software editors.<ref name="nestor">{{Cite news |last=Nestor |first=Marius |date=2 May 2022 |title=Roundup of Xfce's Apps Update for April 2022: New Releases of Mousepad, Xfce Terminal, and Thunar |work=Linux Today |url=https://www.linuxtoday.com/developer/roundup-of-xfces-apps-update-for-april-2022-new-releases-of-mousepad-xfce-terminal-and-thunar/ |access-date=22 August 2022 |archive-date=15 August 2022 |archive-url=https://web.archive.org/web/20220815010916/https://www.linuxtoday.com/developer/roundup-of-xfces-apps-update-for-april-2022-new-releases-of-mousepad-xfce-terminal-and-thunar/ |url-status=live }}</ref> It closely follows the [[GTK]]-system release cycle.

=== Parole ===
[[File:Parole Media Player 1.0.5 (2019-11).png|thumb|Parole 1.0.5 (2019–11)<ref>{{cite web |url=https://mail.xfce.org/pipermail/xfce/2019-November/036740.html |title=ANNOUNCE: parole 1.0.5 released |publisher=Mail.xfce.org |date= 15 November 2019|accessdate=2022-08-11 |archive-date=14 August 2020 |archive-url=https://web.archive.org/web/20200814120756/https://mail.xfce.org/pipermail/xfce/2019-November/036740.html |url-status=live }}</ref>]]
[[File:Parole media player Xubuntu 20.04.png|thumb|Parole 1.0.5]]

''Parole'' is a simple media player based on the [[GStreamer]] framework. It is designed with simplicity, speed and resource usage in mind, and is part of the Xfce Goodies<ref>{{cite web|url=https://docs.xfce.org/apps/parole/start|title=apps:parole:start [Xfce Docs]|website=docs.xfce.org|access-date=2019-02-23|archive-date=14 February 2019|archive-url=https://web.archive.org/web/20190214061743/https://docs.xfce.org/apps/parole/start|url-status=live}}</ref> and uses at least three libraries from the Xfce project (libxfce4ui, libxfce4util, and libxfconf).<ref>{{cite web |title=Debian -- Details of package parole in bullseye |url=https://packages.debian.org/bullseye/parole |access-date=3 May 2020 |archive-date=18 March 2022 |archive-url=https://web.archive.org/web/20220318033325/https://packages.debian.org/bullseye/parole |url-status=live }}</ref>

It is similar to ''[[GNOME Videos]]'', but it has some advantages and disadvantages compared to it:

;Advantages
* It has (X11/[[XShm]]/[[XVideo|Xv]]) video output that provides a much higher frame rate than Clutter-based video output of GNOME Videos which relies upon OpenGL or OpenGL ES for rendering
* Traditional text-based playlist on the main window for both audio and video files which provides an easy and fast switch between the files and shows their time
* [[Audio visualization]]
* Showing a banner upon the videos that have multiple audio or subtitle files

;Disadvantages
* Lacks a mechanism to speed up or slow down the media playback<ref>{{cite web|url=https://bugzilla.xfce.org/show_bug.cgi?id=13550|title=13550 – No way to speed up or slow down video playback|access-date=3 May 2020|archive-date=15 June 2020|archive-url=https://web.archive.org/web/20200615022208/https://bugzilla.xfce.org/show_bug.cgi?id=13550|url-status=live}}</ref>
* Lacks many advanced features of GNOME Videos
* As of version 1.0.5 (2019–11) it cannot run under [[Wayland (display server protocol)|Wayland]]

=== Ristretto ===
An [[image viewer]] (supporting slideshow mode). Ristretto can operate on folders of images, and display their thumbnails in addition to the active image.<ref>{{cite web |last1=Nesbitt |first1=Scott |title=4 lightweight image viewers for the Linux desktop |url=https://opensource.com/article/17/7/4-lightweight-image-viewers-linux-desktop |website=Opensource.com |access-date=15 April 2020 |archive-date=28 September 2020 |archive-url=https://web.archive.org/web/20200928143617/https://opensource.com/article/17/7/4-lightweight-image-viewers-linux-desktop |url-status=live }}</ref>

=== Xfburn ===
A CD/DVD [[optical disc authoring software]]. Starting with the 4.12 release of Xfce, Xfburn is also able to burn Blu-ray discs.

=== Xfce Screensaver ===
A screen saver and session-locking program first packaged with the 4.14 release of Xfce. It uses screensaver themes compatible with Xscreensaver.<ref>{{cite web |title=apps:screensaver:start |url=https://docs.xfce.org/apps/screensaver/start |website=Xfce.org |access-date=10 November 2019 |archive-date=10 November 2019 |archive-url=https://web.archive.org/web/20191110165040/https://docs.xfce.org/apps/screensaver/start |url-status=live }}</ref> Although forked from MATE Screensaver, it depends only on Xfce libraries.
