EDIT: The original question asked for a real-time solution. I am not sure this is necessary. It should be about as fast as sending a standard SMS text message.

I want to integrate group chat in my android / ios app. There is a similar question found here, but the answers are old and I would like to see if there are any new / better solutions.

I am currently using multiple AWS services in my app, and would like to keep my chat solution in the same ecosystem. However, if there is a solution outside of AWS that is much easier to implement with good results, I am open to the suggestion.

Based on my research I have come across a couple of possibilties:

Requirements for my chat:

  • Would like to be able to support up to 500 people per chat group

  • Usable from the web via online portal that has the same general functionality as the mobile app

  • Needs to be scalable to handle thousands of groups

  • Needs to handle emojies (cross platform)

  • Needs to allow for file transfers. Images and GIFs at the very least.

  • Send push notifications to users who have elected to recieve them when they are not currently active in the group

Are either of my possiblities a good fit for my requirements? Which would be the easiest to implement? Are there other, easier solutions inside of AWS? Outside of AWS?

Take a look at https://github.com/tinode/chat

It's not a 100% what you want but close. There is a third-party DynamoDB adapter for it: https://github.com/riandyrn/chat

I am posting this answer to close the question. I ended up switching from AWS to Google Firebase in order to use the Real Time Database.

There is a chat example here that might help anyone that stumbles onto this question.
