Register your .BIO domain

For the sciences and beyond

Why choose a .BIO domain?

Biology, biography, biophysics, biosphere, biotech, biopic. The term "bio" has many uses, and the .bio top-level domain (TLD) can be used as a URL extension for a multitude of different industries, sciences, and studies.

Is a .BIO domain extension right for me?

Because the .bio TLD represents a complex prefix (the Greek root can be found in the words of over six different languages), it's an internationally recognized and expansive extension for broad use. This is a perfect domain choice for researchers, scientists, directors, writers, and historians alike.
