Open Source

At Yoast, open source is at the heart of what we do. We even dare say that the existence of our company, is partly due to the open source model. We truly believe that with openness and joint efforts we can create better code, products, websites and perhaps even a better world.

That’s why all our plugins are open source, as is our flagship plugin, Yoast SEO. We don’t just open up the source code, but we encourage other people to help us improve it as well. In return, team Yoast also contributes to the betterment of WordPress itself.
