Philip kindly posted the link, but I can also say a bit about it. My project using rqlite is a bot for Telegram that sends alerts and provides info. I also operate an instance of this bot that serves a small but substantial group of users.

My motivation in adapting the bot to work with rqlite was looking for a low resistance path to higher availability. I store the small amount of state that the bot requires in rqlite and also use it to implement a simple leader election.
