What is Open Source Software?
Open source software is free to use, free to understand, free to modify, and free to share with others. Major open source projects, like TYPO3 CMS, attract thousands of developers and businesses who collaborate on improving and maintaining it.
During the last decade, technical executives—CIOs and CTOs—have concluded that open source is a safe bet: secure and of high quality. Microsoft moved into open source long ago, and recently purchased GitHub, a popular collaboration platform for open source projects. More and more governments have moved to an “open source first” policy because of benefits including improved ROI, reusable functionality, access to local service providers, and more.
