Opinions on any of these in-app user onboarding tools?

Hey guys,

We are at a stage in which it's sort of difficult to manage onboarding though live chat, we are still a relatively small team compared to the number of sign-ups.

I'm not a fan of user mass mailing, so I'd like to avoid it, whenever possible.

So, I will need one of those tools that onboard users in app, with overlay menus and tip boxes, logical path and so on.

The ones I find interesting (and startup-friendly) are the following:

FREE

• https://introjs.com/ (FREE)
• https://github.com/LinkedInAttic/hopscotch

PAID / FREEMIUM

• https://www.usetiful.com/pricing
• https://www.pendo.io/pricing/
• https://stonly.com

Have you used any of these? Opinions?

Thanks!
