I chose Flutter+Supabase as a tech stack to build kinda Slack clone. There are plenty of simplistic examples of real-time chat apps with Supabase, but I wonder if anyone had success with it in real life scenarios with any substabtial userbase (say, 1k+ active users online).<p>Another thing that I'm concerned about is whether I would be able to run it as a self-hosted app.
We have customers receiving many millions of requests per day, and hundreds of thousands of users. It will be able to handle your workload, probably even on the free tier
I hope it's suitable because I will be using as well for an app that will have 1k+ user base. As far as self-hosting goes, if you're planning on using Supabase Realtime, it can be self-hosted along with the other pieces of the Supabase stack.
