Homepage: Betterbird. Simply better.
Download: Betterbird: Downloads


Betterbird is a fine-tuned version of Mozilla Thunderbird, Thunderbird on steroids, if you will.

Betterbird is better than Thunderbird in three ways: It contains new features exclusive to Betterbird, it contains bug fixes exclusive to Betterbird and it contains fixes that Thunderbird may ship at a later stage. Please refer to this feature table for examples. This should give you an impression of where the project is headed.

Easy adoption: You can install Betterbird at the same time as Thunderbird and run them on the same profile. That means that you can try out Betterbird with zero hassle, and go back to Thunderbird if you don't like it - which is unlikely. Please read the fine print on our support page.

More information on why we're doing the project can be found at the FAQ.

Betterbird 115.5.0 released on 27th November 2023​

Today we are shipping Betterbird version 115.5.1-bb19. Please refer to the release notes for details.

German, Dutch, French, Spanish, Italian, Portuguese, Polish, Russian, Czech, Albanian, Japanese and Chinese localisations available, other languages on request. A portable version for Windows is also available. There's also a Mac build in English only, which can be localised using Betterbird language packs.
