Koi is a free, open-source browser for macOS, made by Alex Whalen. You can use it for anything, personal or commercial.

License

Koi’s source code is released under the Mozilla Public License 2.0 and is available on GitHub, where you can also report bugs. You can use, study, change and share it under that license. The license covers the code; the Koi name and logo aren’t included.

Beta

Koi is in beta. Features may change, break or be removed between releases, so keep backups of anything important.

Other services

The websites, search engines, extensions, Mozilla accounts and AI agents you use with Koi are run by others, under their own terms.
