Froala allows HTML editors to use their services in the web browser for free, but it has multiple subscription tiers as well. Subscription prices start at $199 per year (Basic), with the next at $899 (Pro), and finally, at $1,999 per year (Enterprise). All three of these subscription tiers allow for unlimited active users per month, free updates for the latest version, and self-hosted content.
The two more expensive tiers allow for unlimited domains, whereas Basic only allows three at once, and offers support from the company, where Basic only offers community-based support.
We have been gushing over this, and we tried to come up with any cons to account for, but to no avail. The only cons you could actually come up with, to be honest, are to do with WYSIWYG editors in the first place. If you are down to try a WYSIWYG editor though, this is one of your best bets.
