The lightweight Tox client.
Tox is a peer-to-peer, end-to-end encrypted, instant messaging protocol, with end-to-end encryption as its default and only mode.
µTox is cross-platform: Primary support for Windows 7+ and Linux, secondary support for OpenBSD, FreeBSD, NetBSD, and DragonFlyBSD. MacOS is unmaintained (needs your contributions).
µTox is multi-lingual: Complete translations for German, Russian, Swedish, Polish, Spanish, Hungarian, Estonian, Ukrainian, and Bulgarian. Partial translations to many more languages.
Just like Toxcore, µTox is still alpha software, so you may encounter bugs, or maybe a crash or two. µTox also needs your help, if you do encounter any bugs or problems please open an issue. If you do not have a GitHub account, you may also send an email directly to avoidr.
