Open Source

At Yoast, open source is at the heart of what we do; even the existence of our company is partly due to the open source model. We believe openness and collaboration lead to better code, better websites and maybe 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 – we encourage others to help improve it, too. In return, team Yoast also contributes to the betterment of WordPress itself.
