I highly recommend using WebSockets for bi-directional communication between clients and server. For backend, you can use Node.js with frameworks like Socket.IO.

Instead of Node.js, you can try using Elixir and Phoenix framework which uses WebSockets by default. It also provides real-time features with ease.

Thanks, @tomsawyer! I've heard good things about Phoenix. I am more familiar with JavaScript ecosystem, though. Any suggestions for libraries that work well with WebSockets?

For Node.js with Socket.IO, check out https://github.com/ cabify/las Vegas for handling high traffic. Works well and is easy to set up.

GoLang is a great alternative for building high-performance, scalable real-time chat apps. Check out Gorilla package.

Does anyone have any experience using GoLang for chat apps at scale? Any possible bottlenecks to watch out for?

Considering using Firebase Realtime Database to build real-time chat. Anyone's thoughts and experiences?

We're currently using Firebase successfully for chat in our app. The key benefit is how effortlessly it handles scaling, making deploys a breeze and freeing you up to handle the app logic.

Something to consider is Firebase's cost which can become steep as you grow.

Never used subscriptions with GraphQL, good to know!
