They also have an extension (which is the default version on Linux/Chromebooks) that does not require the 1Password application. I have used it since the betas in Linux and it works nicely. Also, this thread seems to imply that having a binary component is always bad. It can also increase security. If the extension is rate-limited in retrieving passwords from a vault, then a compromised browser can only extract a limited number of passwords, whereas with a browser-native extension the attacker could extract all passwords.
