Rated 1 out of 5 stars

I was a long-time user of Scriptish but recently I moved back to Greasemonkey.

Ironically, the developer all but abandoned it while Greasmonkey is actively maintained and supported.

Scriptish does not implement some functions used by Greasemonkey (like GM_info) which causes scripts to fail installing.

Last version was released Released June 14, 2013. In the same period of time Greasmonkey released 6 versions and countless betas.

103 open issues on Github, some opened over 2 years ago.

Oh, and good luck trying to contact the developer.

Avoid.
