Free, secure and fast downloads from the largest Open Source applications and software directory SourceForge. Business models for open source software. Open source software is widely used both as independent applications and as components in non open source applications. Many independent software vendors ISVs, value added resellers VARs, and hardware vendors OEMs or ODMs use open source frameworks, modules, and libraries inside their proprietary, for profit products and services. From a customers perspective, the ability to use open technology under standard commercial terms and support is valuable. They are willing to pay for the legal protection e. QA, and professional supporttrainingconsulting that are typical of commercial software, while also receiving the benefits of fine grained control and lack of lock in that comes with open source. FundingeditMuch unlike proprietary off the shelf software that come with restrictive licenses, open source software is distributed freely, through the web and in physical media. Because creators cannot require each user to pay a license fee to fund development this way, a number of alternative development funding models have emerged.

These customers pay developers to have this software developed according to their own needs and they could also closely direct the developers work. If both parties agree, the resulting software could then be publicly released with an open source license in order to allow subsequent adoption by other parties. That agreement could reduce the costs paid by the clients while the original developers or independent consultants can then charge for training, installation, technical support, or further customization if and when more interested customers would choose to use it after the initial release.

Another approach to funding is to provide the software freely, but sell licenses to proprietary add ons such as data libraries. For instance, an open source CAD program may require parts libraries which are sold on a subscription or flat fee basis. Open source software can also promote the sale of specialized hardware that it interoperates with, some example cases being the Asterisk telephony software developed by PC telephony hardware manufacturer Digium and the Robot Operating System ROS robotics platform by Willow Garage and Stanford AI Labs. Many open source software projects have begun as research projects within universities, as personal projects of students or professors, or as tools to aid scientific research. The influence of universities and research institutions on open source shows in the number of projects named after their host institutions, such as BSD Unix, CMU Common Lisp, or the NCSA HTTPd which evolved into Apache. Companies may employ developers to work on open source projects that are useful to the companys infrastructure in this case, it is developed not as a product to be sold but as a sort of shared public utility. A local bug fix or solution to a software problem, written by a developer either at a companys request or to make hisher own job easier, can be released as an open source contribution without costing the company anything. A larger project such as the Linux kernel may have contributors from dozens of companies which use and depend upon it, as well as hobbyist and research developers. A new funding approach for open source projects is crowdfunding, organized over web platforms like Kickstarter, Indiegogo, or Bountysource. ChallengeseditOpen source software can be sold and used in general commercially. Also, commercial open source applications have been a part of the software industry for some time. While commercialization or funding of open source software projects is possible, it is considered challenging. Since several open source licenses stipulate that authors of derivative works must distribute them under an open source copyleft license, ISVs and VARs have to develop new legal and technical mechanisms to foster their commercial goals,7 as many traditional mechanisms are not directly applicable anymore. Traditional business wisdom suggests that a companys methods, assets, and intellectual properties should remain concealed from market competitors trade secret as long as possible to maximize the profitable commercialization time of a new product. Open source software development minimizes the effectiveness of this tactic development of the product is usually performed in view of the public, allowing competing projects or clones to incorporate new features or improvements as soon as the public code repository is updated, as permitted by most open source licenses. Also in the computer hardware domain, a hardware producer who provides free and open software drivers reveals the knowledge about hardware implementation details to competitors, who might use this knowledge to catch up. Therefore, there is considerable debate about whether vendors can make a sustainable business from an open source strategy. In terms of a traditional software company, this is probably the wrong question to ask. Looking at the landscape of open source applications, many of the larger ones are sponsored and largely written by system companies such as IBM who may not have an objective of software license revenues. Other software companies, such as Oracle and Google, have sponsored or delivered significant open source code bases. These firms motivation tends to be more strategic, in the sense that they are trying to change the rules of a marketplace and reduce the influence of vendors such as Microsoft. Smaller vendors doing open source work may be less concerned with immediate revenue growth than developing a large and loyal community, which may be the basis of a corporate valuation at merger time. ApproacheseditA variety of open source compatible business approaches have gained prominence in recent yearsaccording to whom notable examples include dual licensing, software as a service, not charging for the software but for services, freemium, donation based funding, crowdfunding, and crowdsourcing. There are several different types of business models for making profit using open source software OSS or funding the creation. Below are existing and legal commercial business approaches in context of open source software and open source licenses. The acceptance of these approaches varies some of these approaches are recommended like selling services, others are accepted, while still others are considered controversial or even unethical by the open source community. The underlying objective of these business models is to harness the size and international scope of the open source community typically more than an order of magnitude larger than what would be achieved with closed source models for a sustainable commercial venture. The vast majority of commercial open source companies experience a conversion ratio as measured by the percentage of downloaders who buy something well below 1, so low cost and highly scalable marketing and sales functions are key to these firms profitability. Dual licensingeditDual licensing offers the software under an open source license but also under separate proprietary license terms.
