You need something "more" on the website before you ask people to create an account. "Team workspace that stays fast" isn’t clear enough for me, at least. What is a workspace? What does the interface look like? Is it in the browser? Is it an app?
People will go "what is this?", "huh, I’m not gonna make a user for this, can’t tell what it is". Those are my 2 cents.
Thanks, I'll fix that.
+1 to that. As a user, I am tired of having to sign up for an account on a SaaS website or installing an app from Github, only to realize the UI isn't a good fit for me. This will usually result in me bouncing from the app website instead of trying it out.
Suggestion: have a non-login demo available on your website, and high-res screenshots/animed gif of the app in action on your Github repo.
