I have put together a list of most famous and popular applications and software packages written in C or C++ programming languages.  The surprising thing is that majority of these applications are commonly used in our daily routine. Many tech giants such as Google, Microsoft, Apple and Adobe have number of applications written in C/C++. I have included both C and C++ as the majority of these applications are partly or completely written in either of the programming language.

These applications are mainly, but not limited to, Operating Systems, Device Drivers, Compilers, Graphical User Interfaces (GUIs) and Integrated Development Environments (IDEs) written in C/C++. Operating Systems include Windows 95, 98, 2000, XP, Apple OS X, Symbian OS and BeOS. General applications include Mozilla Firefox, MySQL Server, Adobe Photoshop and Maya 3D Animation software.

Applications written in C/C++

Adobe Systems


Many of the major applications of adobe systems are developed in C++ programming language.

These applications include Adobe Photoshop and Image Ready, Illustrator and Adobe Premier. Adobe has released a lot of open-source code in the past, mostly in C++, and their developers have been active in the C++ community.

Google Applications


Google developed some of the applications using C++. These include Google file system and Google Chromium browser and MapReduce large cluster data processing.

Google open source community has over 2,000 projects and many of them use C or C++ as their main Programming languages. These include WebRTC, gRPC and DeepMind Lab, which freely available as open source at GitHub.

Many a parts of Android mobile operating system, primarily designed for handheld devices, which uses modified version of the Linux kernel. Both C and C++ are primary development languages for Linux kernel development.

Mozilla Firefox and Thunderbird


Mozilla Internet browser i.e. Firefox and email client i.e. Thunderbird are both written in C++ programming language.

Both are open source projects and their source code can be downloaded from Mercurial repositories.

The C++ source code of these applications can be found on MDN web docs which is maintained by open community of developers.

MySQL Server


MySQL is one of the world’s most popular open source database software. It has over 100 million copies downloaded or distributed throughout its history. (source: DB-Engines)

Many of the world’s largest and fastest-growing organizations use MySQL to save time and money; powering their high-volume web sites, critical business systems, and packaged software.

MySQL open source C++ code is available at GitHub.

Alias System – Autodesk Maya


Maya 3D software was originally developed by Alias System Corporation and was later carried over by Autodesk.

Maya® 3D animation, modeling, simulation, and rendering software provides an integrated, powerful tool set. Use it for animation, environments, motion graphics, virtual reality, and character creation.

AutoDesk open source center hosts plenty of C++ projects.

Winamp Media Player


Winamp is the ultimate media player, allows you to manage audio and video files, rip and burn CDs, enjoy free music, access and share your music and videos remotely.

Winamp supports dozens of media file formats, plugin systems, media library, media monitor and tons of different skins.

It was written in C and C++ and initially released in 1997.
