What Is Open Source?

What Is Open Source?

Open source software is software whose code is published openly, free for anyone to use, inspect, improve and share, usually under a licence that sets out how it may be used.

It matters because a great deal of the modern web runs on open source. It lowers costs, avoids lock-in to a single vendor, and benefits from thousands of contributors finding and fixing issues.

An Everyday Analogy

Open source is like a community recipe book that anyone can read, cook from and improve. Because so many people use and refine the recipes, the best ones become very reliable.

  • The code is public and free to use.
  • Anyone can inspect it for security.
  • A community maintains and improves it.
  • Licences define how it may be used.

Why It Matters to You

Building on open source brings practical advantages for your budget and your independence.

  • No licence fees for the core software.
  • Freedom to move between suppliers — no lock-in.
  • Transparency you can have independently reviewed.
  • Mature, widely trusted tools behind your product.

Frequently Asked Questions

Is open source less secure because the code is public?

Often the opposite — many eyes review the code, so problems tend to be found and fixed quickly.
