Yes there is
$3.50/user/month just for that seems a bit steep
Actually Zulip may be the most affordable open source chat app out there. Those $3.5/user/month only come into play if you have more than ten users and want to have mobile notifications using Zulip's relay server.
For Mattermost, you only get a basic version if you don't pay at least $10/user/month for a non-open source version.
Rocket.chat limits the open source community edition to 10,000 notifications per month. Depending on the usage, this may not be enough even for ten users. Yes, you could use the starter edition up to 25 users for free. But that is apples and oranges as it is not open source anymore.
And with Cloudron you can have multiple instances running, so if you are really on a budget, but want mobile notifications, each team of less than 10 people gets its own instance of Zulip.
