Is Gmail Lab API open?

Question

I am thinking about writing a plugin for email application. It can be put on Gmail Labs. It can be thunderbird plugin or even chrome/firefox plugin. But to get the most exposure I should put it on Gmail Labs if possible. Actually, I don't know if it's possible at all. BTW, I'm aware of this. Let me know what you think.

Answer 1

No, Gmail Labs is not open to external contributions. However, Gmail users can add external gadgets to Gmail.
