SeaMonkey Development Resources

The SeaMonkey Project is constantly in need of developers, testers, marketers and other contributors to our success. If you want to help, you can find some resources here.

Our Getting Involved with SeaMonkey page is another good entry point to helping out our project, as well as the SeaMonkey pages on the Mozilla wiki - and the SeaMonkey blog features development news every now and then.


You can help make SeaMonkey available in your language! This process not only involves translating text but also adapting resources to fit for people in your local environment, which is why we call it "localization", often abbreviated to "L10n" (an "L", 10 other characters, then an "n"). Get more information about how to help with this on our SeaMonkey Localization wiki page.


Testing our code is a very major and important task in every software project, and the good thing is that anyone can participate in that by downloading "Nightly" builds, using them and reporting bugs.

"Nightly" builds are versions of our software that are made every night from the most current source code, the most experimental and dynamically changed versions are from the so-called "trunk" of the development tree, available as trunk nightly builds. Those are the versions that need the highest amount of testing, often contain exciting new features but also can easily crash or destroy any of your data (some people claim they can also eat children or make your kitchen go up in flames, but we have no actual evidence of such things actually happening - yet).
To cut things short, we're happy about everyone testing those builds, but be very careful and keep backups of your data if you do so, as some of the code you're testing might not have been tested at all before.

Our Getting Involved page and the Mozilla wiki on SeaMonkey QA (Quality Assurance) offer some good additional info about testing and helping us improve our software quality through that.

Marketing And Other Contributions

Even as a normal user of stable SeaMonkey versions, you can help the project a lot by spreading the word and telling all your fellow friends, web developers and other people around you about our great software.

You can use our logo & artwork for pointing other people to SeaMonkey, as that is explicitly allowed by our SeaMonkey trademark policy.

The merchandise available from the SeaMonkey shop can also help you in spreading the word.

If your company is willing to contribute development resource to SeaMonkey, you can get in touch with SeaMonkey e.V. or SeaMonkey Council to discuss details.

And, last but not least, you can donate money to the SeaMonkey project via the SeaMonkey Association (SeaMonkey e.V.). If your company is considering donating to SeaMonkey, please read the same section about how to sponsor our project.
