We (Chatlio) like to think we started the trend ;) But verify that with the wayback machine. :) And if imitation is a form of flattery, we are very &quot;flattered&quot; by these.<p>But in all seriousness, before you install a Slack App, make sure to verify how much permissions they request. We at Chatlio strive for asking for as little permission as possible.  If some feature requires more, we ask for that on an as-needed basis after signup.
