Open Source software is defined as software in which source code is open for programmers to modify, share, and create applications without paying licensing fees. Developers tend to love Open Source software, mainly because it drives innovation and creativity. Luckily for them, ProgrammableWeb lists hundreds of Application Programming Interfaces, or APIs, in its Open Source category.
The category covers a huge variety of open projects that developers can integrate with to create applications. These categories include Government, Business, Artificial Intelligence, Speech, Recognition, Automobile, Music and Arts, IoT, Food and Entertainment databases, DevOps, Application Development, Healthcare & Fitness, and even Finance & Banking.
Please note: It’s important to distinguish the difference between an Open API (or Public API), to an Open Source API. An Open API allows a company to publicly expose data and functions for developers to create third-party applications. The antithesis to an Open API would be a Private API, which is used to facilitate integrations within internal systems. An Open Source API, on the other hand, is simply an integration tool that connects developers to an Open Source product or service. (Read more about public vs. private APIs in our series about Maximizing the ROI on Your API. )
Whichever Open Source API a developer may be on the hunt for can probably be found in the ProgrammableWeb Open Source category. In this article, we list the twelve most popular APIs in our directory for integrating with Open Source products and services, based on website page visits.
