What is Dropbox?

For users looking for a central repository to share, sync, and store files, Dropbox is a secure cloud storage service for virtually any size and media type. Dropbox offers anytime, anywhere access, and real-time syncing across all devices. Users can access Dropbox accounts with desktop apps on Windows or Mac, with its mobile app for iOS and Android mobile devices, and any web browser.

Popular Dropbox Features  

Dropbox was introduced in 2007 as a file management system with a free plan to make it accessible to everyone. Since then, Dropbox has grown its offerings to include: 

  • File storage and syncing
  • Built-in word processor (Dropbox Paper)
  • Commenting and collaboration
  • Backup and file recovery
  • Ransomware protection
  • Multi-factor authentication

Others have tried to emulate Dropbox’s features giving rise to a host of Dropbox alternatives. Businesses that want control over their options can turn to free and open source cloud storage and file hosting solutions.

What Does Free and Open Source Mean?

Free and open source software is software for which anyone can inspect, modify, and enhance the source code, according to Opensource.com. Unlike proprietary (or closed source) software controlled by the business that owns it, like Dropbox, open source software is developed with the intent and permission for others to use the software for any purpose they wish. When open source code is modified, the licensing usually stipulates it must be released to the community.

Benefits of Open Source Software

Open source software is popular for cloud-based data storage, file storage, and remote collaboration and is critical to internet-based programming. Linux is the largest and best-known example of open source software, and other examples include LibreOffice and Mozilla Firefox. Here are some examples of open source software benefits:

Community support. Open source software has a community of developers behind it creating an open exchange of ideas and knowledge, referred to as the “open source way.”

Free software. “Free” in “free and open source software” refers to the freedom of use instead of free of charge. However, open source software usually has a version available for free or a nominal licensing charge.

Secure and stable. With a community accessing the code, users are comfortable that software bugs are found and fixed quickly. Open source software often uses zero-knowledge, or end-to-end encryption, and is HIPAA and GPDR compliant.

Tailored software. Small business owners can hire open source programmers to modify the software to meet their business needs.

Business owners are responsible for managing and securing the code, and they can be liable for any issues the software causes to their business, customers, or clients. Companies are discouraged from using open source software for financial and HR functions.
