Source code

The source code is available either as a tar package or from the source repository.

  • Source Code Tarball (bzip, 59 MB) - note that it doesn't unpack a subdirectory itself, so create a directory to unpack it in.
  • The README file explains how to pull SeaMonkey 2.1 Release Candidate 1 from the source repository.

Language Packs

Experimental builds/languages

Those languages didn't meet the quality criteria for official builds but should be fully usable. Probably they have not completely finished localizing and some parts might still be in English. The localizers would welcome your help to complete the work and make it into the official set for the next release!
