@jpostma they took it private without any notice, which I find quite problematic for an OSS project.

I hope (and expect) that someone will take up the project. The latest code can be found at https://github.com/enthec/webappanalyzer. This repository may also become the successor to #wappalyzer.

I didn't know #enthec before, but I'm willing to give them the benefit of the doubt.
