The cost to self-host a chat app depends on several factors like the size of the communication app, scalability factor, number of users in a chat platform, number of features, and other factors. Therefore, considering all the above factors, if you search in the market for the overall cost of self-hosting a chat app, you can expect somewhere between S50 to $10,000 per month.  However, if you are using MirrorFly's self-hosted chat solution, you can self-host apps, avail 100% customizations, and make a secure and scalable white-label chat solution for custom pricing.
