SourceForge is a web-based service that offers software developers a centralized online location to control and manage free and open-source software projects. It provides a source code repository, bug tracking, mirroring of downloads for load balancing, a wiki for documentation, developer and user mailing lists, user-support forums, user-written reviews and ratings, a news bulletin, micro-blog for publishing project updates, and other features.

SourceForge was one of the first to offer this service free of charge to open source projects.[5] Since 2012, the website has run on Apache Allura software. SourceForge offers free access to hosting and tools for developers of free / open-source software.

As of March 2014, the SourceForge repository claimed to host more than 430,000 projects and had more than 3.7 million registered users.[6] The domain attracted at least 33 million visitors by August 2009 according to a survey.[7]

From mid-2013 SourceForge introduced a program called DevShare, which offered projects a way to monetize their downloads by having an optional download that includes prompts for the user to download additional software that is not part of the project. Negative community reactions to the partnership program led to a review of the program, which was nonetheless opened up to all SourceForge projects on February 7, 2014.[8][9] The program was cancelled by new owners BIZX, LLC on February 9, 2016;[10] on May 17, 2016 they announced that it would scan all projects for malware and display warnings on downloads.[11]

SourceForge is a web-based source code repository. It acts as a centralized location for free and open-source software projects. It was the first to offer this service for free to open-source projects. Project developers have access to centralized storage and tools for managing projects, though it is best known for providing revision control systems such as CVS, SVN, Bazaar, Git and Mercurial.[12] Major features (amongst others)[13] include project wikis, metrics and analysis, access to a MySQL database, and unique sub-domain URLs (in the form

The vast number of users at (over 3 million as of 2013)[7] exposes prominent projects to a variety of developers and can create a positive feedback loop. As a project's activity rises,'s internal ranking system makes it more visible to other developers through SourceForge directory and Enterprise Directory.[14][15] Given that many open-source projects fail due to lack of developer support, exposure to such a large community of developers can continually breathe new life into a project.

Revenue model

SourceForge's traditional revenue model is through advertising banner sales on their site. In 2006 SourceForge Inc. reported quarterly takings of US$6.5 million.[16] In 2009 SourceForge reported a gross quarterly income of US$23 million through media and e-commerce streams.[17] In 2011 a revenue of 20 million USD was reported for the combined value of the SourceForge, slashdot and freecode holdings, prior to SourceForge's acquisition.[18]

Since 2013 additional revenue generation schemes, such as bundleware models,[19] have been trialled, with the goal of increasing SourceForge's revenue. The result has in some cases been the appearance of malware bundled with SourceForge downloads.[20] On February 9, 2016, SourceForge announced they had eliminated their DevShare program practice of bundling installers with project downloads.[21]


SourceForge, founded in 1999 by VA Software, was the first provider of a centralized location for free and open-source software developers to control and manage software development and offering this service without charge.[5] The software running the SourceForge site was released as free software in January 2000[22][23] and was later named SourceForge Alexandria.[24] The last release under a free license was made in November 2001;[25] after the dot-com bubble, SourceForge was later powered by the proprietary SourceForge Enterprise Edition, a separate product re-written in Java[26][27] which was marketed for offshore outsourcing.[28]

SourceForge has been temporarily banned in China three times: in September 2002[29], in July 2008 (for about a month)[30][31] and on August 6, 2012 (for several days).

In November 2008, SourceForge was sued by the French collection society Société civile des Producteurs de Phonogrammes en France (SPPF) for hosting downloads of the file sharing application Shareaza.[32]

In 2009 SourceForge announced a new site platform known as Allura, which would be an extensible, open source platform licensed under the Apache License, utilizing components such as Python and MongoDB, and offering REST APIs.[33] In June 2012 the Allura project was donated to the Apache Software Foundation as Apache Allura.[34][35]

In September 2012 SourceForge, Slashdot, and Freecode were acquired from Geeknet by the online job site for $20 million, and incorporated into a subsidiary known as Slashdot Media.[36][37] In July 2015 Dice announced that it planned to sell SourceForge and Slashdot,[38] and in January 2016 the two sites were sold to the San Diego-based BIZX, LLC for an undisclosed amount.[39]

On September 26, 2012, it was reported that attackers had compromised a SourceForge mirror, and modified a download of phpMyAdmin to add security exploits.[40]


Some of SourceForge's monetization practices have been met with criticism by developers and end users.

DevShare adware Diagramm
Number of hosted projects, 2000-2010

In July 2013 SourceForge announced that it would provide project owners with an optional feature called DevShare, which places closed-source ad-supported content into the binary installers and gives the project part of the ad revenue.[41] Opinions of this new feature varied; some complained about users not being as aware of what they are getting or being able to trust the downloaded content, whereas others saw it as a reasonably harmless option that keeps individual projects and users in control.[42]

In November 2013 GIMP, a free image manipulation program, removed its download from SourceForge, citing misleading download buttons that potentially confuse customers, as well as SourceForge's own Windows installer, which bundles potentially unwanted programs. In a statement, GIMP called SourceForge a once "useful and trustworthy place to develop and host FLOSS applications" that now faces "a problem with the ads they allow on their sites ..."[43][44][45]

In response to the DevShare adware many users and projects migrated to GitHub, other software hosting facilities, or self-host their software.[46][47] In May 2015, SourceForge took control of pages for five projects that had migrated to other hosting sites and replaced the project downloads with adware-laden downloads.[48] Community concerns triggered a prompt review of SourceForge mirroring program, and third-party bundling of mirrored content was discontinued on May 27, 2015.[48]

After SourceForge was sold to BizX in 2016, DevShare was discontinued.[49][50] On May 17, 2016, SourceForge announced that they were now scanning all projects for malware, and displaying warnings on projects detected to have malware.[51]

Project hijackings and bundled malware

GIMP, who discontinued their use of SourceForge as a download mirror in November 2013,[43][52] reported in May 2015 that SourceForge was hosting versions of their Windows binaries that "put other software apart from GIMP on our users' systems" on their Open Source Mirror directory,[53][54] which SourceForge claims is a collection of abandoned projects.[55][56] This came despite SourceForge's commitment in November 2013 to never bundle adware with project downloads without developers' consent.[52][53][57] GIMP said "To us, this firmly places SourceForge among the dodgy crowd of download sites."

On June 1, 2015, SourceForge claimed that they stopped coupling "third party offers" with unmaintained SourceForge projects.[58] Since this announcement was made, a number of other developers have reported that their SourceForge projects had been taken over by SourceForge staff accounts (but have not had binaries edited), including nmap,[57][59] and VLC media player.[60] On June 18, 2015, SourceForge announced that SourceForge-maintained mirrored projects were removed, and anticipated the formation of a Community Panel to review their mirroring practices.[61] However, no such Community Panel ever materialized.

Reception - Download Forbidden
An error message seen by someone attempting to access SourceForge from Iran, an ITAR-restricted country.


As of May 2013, the SourceForge repository hosted more than 300,000 projects and had more than 3 million registered users,[63] although not all were active. The domain attracted at least 33 million visitors by August 2009 according to a survey.[7]

Country restrictions

In its terms of use,[64] SourceForge states that its services are not available to users in countries on the sanction list of the U.S. Office of Foreign Assets Control (including Cuba, Iran, North Korea, Sudan and Syria). Since 2008 the secure server used for making contributions to the site has blocked access from those countries. As of January 2010 the site had blocked all access from those countries, including downloads. Any IP address that appeared to belong to one of those countries could not use the site.[65] A month later SourceForge relaxed the restrictions so that individual projects could indicate whether or not SourceForge should block their software from download to those countries.[66]

Crimea has been blocked since 1 February 2015.[67][68][69]

7-Zip is a free and open-source file archiver, a utility used to place groups of files within compressed containers known as "archives". It is developed by Igor Pavlov and was first released in 1999. 7-Zip uses its own 7z archive format, but can read and write several other archive formats. The program can be used from a command-line interface as the command p7zip, or through a graphical user interface that also features shell integration. Most of the 7-Zip source code is under the GNU LGPL license; the unRAR code, however, is under the GNU LGPL with an "unRAR restriction", which states that developers are not permitted to use the code to reverse-engineer the RAR compression algorithm.

Ares Galaxy

Ares Galaxy is an open source peer-to-peer file sharing application that uses its own decentralized supernode/leaf network. It was spun off from the gnutella network in 2002, and is hosted on Ares Galaxy has a simple, quick access interface with a built in audio/video viewer. The latest versions also support the BitTorrent protocol and Shoutcast radio stations.

Audacity (audio editor)

Audacity is a free and open-source digital audio editor and recording application software, available for Windows, macOS/OS X and Unix-like operating systems. Audacity was started in the fall of 1999 by Dominic Mazzoni and Roger Dannenberg at Carnegie Mellon University and was released on May 28, 2000 as version 0.8.As of October 10, 2011, it was the 11th most popular download from SourceForge, with 76.5 million downloads. Audacity won the SourceForge 2007 and 2009 Community Choice Award for Best Project for Multimedia. In March 2015 hosting was moved to FossHub and by March, 2019 it had exceeded 70.6 million downloads there.

Comparison of free geophysics software

This is a list of free and open-source software for geophysical data processing and interpretation. The list is split into broad categories, depending on the intended use of the software and its scope of functions.

Notice that 'free and open-source' requires that the source code is available. Simple being 'free of charge' is not sufficient—see gratis versus libre. The reader interested in freeware (just free of charge) software is referred to the list of freeware geophysics software.

Comparison of source-code-hosting facilities

A source-code repository is a file archive and web hosting facility where a large amount of source code, for software or for web pages, is kept, either publicly or privately. They are often used by open-source software projects and other multi-developer projects to handle various versions. They help developers submit patches of code in an organized fashion. Often these web sites support version control, bug tracking, release management, mailing lists, and wiki-based documentation...

People who write software retain their copyright when their software is posted to any code hosting facilities, including the "non-gnu" section of GNU Savannah—with the exception of contributors to Free Software Foundation (FSF)-copyrighted programs at GNU Savannah.


FileZilla is a free software, cross-platform FTP application, consisting of FileZilla Client and FileZilla Server. Client binaries are available for Windows, Linux, and macOS, server binaries are available for Windows only. Both server and client support FTP and FTPS (FTP over SSL/TLS), while the client can in addition connect to SFTP servers.

FileZilla's source code is hosted on SourceForge and the project was featured as Project of the Month in November 2003. However, there have been criticisms that SourceForge bundles malicious software with the application.


Freecode, formerly Freshmeat, is a website owned by BIZX, Inc. It is popular source of open source software for programmers and developers. Among other things, the site also hosted user reviews and discussions. A majority of the software covered is open source for Unix-like systems, although Freecode also covered releases of closed-source, commercial and cross-platform software on Mac OS X and handhelds. Freecode was notable for its age, having started in 1997 as the first web-based aggregator of software releases.The site was renamed from "Freshmeat" to "Freecode" on October 29, 2011, and in September 2012, Dice Holdings acquired the website from Geeknet.Purportedly as a result of low traffic levels, the site is no longer being updated as of June 18, 2014. Because many of the linked software projects are otherwise difficult to find, the site contents have been kept online. After Open Source Initiative co-founder Eric S. Raymond called for a replacement, was created and is accepting submissions.On January 27, 2016, Freecode was sold, along with SourceForge and Slashdot, to current owners BIZX, Inc. The site remains in its archived state, but some discussion is on going to restore it.

GNU Savannah

GNU Savannah is a project of the Free Software Foundation initiated by Loïc Dachary, which serves as a collaborative software development management system for free Software projects. Savannah currently offers CVS, GNU arch, Subversion, Git, Mercurial, Bazaar, mailing list, web hosting, file hosting, and bug tracking services. Savannah initially ran on the same SourceForge software that at the time was used to run the SourceForge portal.Savannah's website is split into two domain names: for software that is officially part of the GNU Project, and for all other software.

Unlike SourceForge or GitHub, Savannah's focus is for hosting free software projects and has very strict hosting policies, including a ban against the use of non-free formats (such as Macromedia Flash) to ensure that only free software is hosted. When registering a project, project submitters have to state which free software license the project uses.


Geeknet, Inc. is a Fairfax County, Virginia–based company that owns the online retailer ThinkGeek and is a subsidiary of GameStop. The company was formerly known as VA Research, VA Linux Systems, VA Software, and SourceForge, Inc.. It was founded in 1993 and was formerly headquartered in Mountain View, California.

Irrlicht Engine

Irrlicht (pronounced [ˈʔɪɐ̯lɪçt] in German) is an open-source game engine written in C++. It is cross-platform, officially running on Windows, macOS, Linux and Windows CE and due to its open nature ports to other systems are available, including FreeBSD, Xbox (up to 1.8.1), PlayStation Portable, Symbian, iPhone and Google Native Client.Irrlicht is known for its small size and compatibility with new and older hardware alike, ease of learning, and a large friendly community. Unofficial bindings for many languages exist including AutoIt, C++Builder, FreeBASIC, GameMaker Language, Java, Lua, .NET, Object Pascal (Delphi), Perl, Python, and Ruby, though most of them have not been maintained for five years or more.

Irrlicht's development began in 2003 with one developer, Nikolaus Gebhardt. Only after the 1.0 release of Irrlicht in 2006 did the team grow to ten members as of 2011, most of them being developers.Irrlicht is a common German term for a will-o'-the-wisp.

The MUTE client is open source software released under the Public domain and includes support for the Linux, Mac OS X and Microsoft Windows computer operating systems.

All MUTE compatible clients use RSA encryption to exchange keys, and AES (128 bits) to encrypt stream data.The design of the MUTE network is vulnerable to a man-in-the-middle attack.

Potentially unwanted program

A potentially unwanted program (PUP) or potentially unwanted application (PUA) is software that a user may perceive as unwanted. It is used as a subjective tagging criterion by security and parental control products.

Such software may use an implementation that can compromise privacy or weaken the computer's security. Companies often bundle a wanted program download with a wrapper application and may offer to install an unwanted application, and in some cases without providing a clear opt-out method.

Antivirus companies define the software bundled as potentially unwanted programs which can include software that displays intrusive advertising (adware), or tracks the user's Internet usage to sell information to advertisers (spyware), injects its own advertising into web pages that a user looks at, or uses premium SMS services to rack up charges for the user. The practice is widely considered unethical because it violates the security interests of users without their informed consent.

Some unwanted software bundles install a root certificate on a user's device, which allows hackers to intercept private data such as banking details, without a browser giving security warnings. The United States Department of Homeland Security has advised removing an insecure root certificate, because they make computers vulnerable to serious cyberattacks.A growing number of open-source software projects have expressed dismay at third-party websites wrapping their downloads with unwanted bundles, without the project's knowledge or consent. Nearly every third-party free download site bundles their downloads with potentially unwanted software.Software developers and security experts recommend that people always download the latest version from the official project website, or a trusted package manager or app store.


Shareaza is a peer-to-peer file sharing client running under Microsoft Windows which supports the gnutella, Gnutella2 (G2), eDonkey, BitTorrent, FTP, HTTP and HTTPS network protocols and handles magnet links, ed2k links, and the now deprecated gnutella and Piolet links. It is available in 30 languages.

Shareaza was developed by Michael Stokes until June 1, 2004, and has since been maintained by a group of volunteers. On June 1, 2004, Shareaza 2.0 was released, along with the source code, under the GNU General Public License (GPL), making it free software.


SmallBASIC is a BASIC programming language dialect with interpreters released as free software under the GNU General Public License version 2.

Stripes (framework)

Stripes is an open source web application framework based on the model–view–controller (MVC) pattern. It aims to be a lighter weight framework than Struts by using Java technologies such as annotations and generics that were introduced in Java 1.5, to achieve "convention over configuration". This emphasizes the idea that a set of simple conventions used throughout the framework reduce configuration overhead. In practice, this means that Stripe applications barely need any configuration files, thus reducing development and maintenance work.
