To the people saying this asset has been abandoned, it isn't. There's still a very active community on Discord and GitHub around this asset. If you're using 2018.x, you need to make sure you have the HLAPI included in your project or it won't build! Thank you for a solid asset and sample project to learn from!

This asset appears to be abandoned. The creators have not answered support or been active for a long time. The asset and Github versions crash in 2018x.

The framework is extremely helpful to start messing with proper netwoking in Unity. I love it.

Be good people, intelligent and a great professional level God. This server is amazing!

The detail and consideration included in Master Server Framework makes it an all-around amazing asset and applicable in any large multiplayer project. Code is well-written and can be extended to meet your needs. I can't believe it's free!

I've tried a few 'Master Server' assets, but this one is best :). In my case, For my turn-based game, i dont really need to have a ServerSpawner and GameServers. It can communicate easily by using lobby. But i have a question about connection limit. What is the max number(+-) of clients connected to MasterServer?

Even though it went open source and it because a bit harder to receive support (though the community is quite helpful) this is still very easily the best option out there (free or paid) that I have used in terms of features, extensibility, ease of user and overall performance. You can quickly and easily add authentication, "rooms" (players can start up their own game rooms), chat, etc hosted on your own linux server (or whatever you prefer).

I downloaded this yesterday. Today I had the demo up and running on Amazon EC2 virtual server and was playing it in 2 rooms from 2 computers with 7 clients. As far as my skill level goes, a month ago I didn't know what an RPC was. Today I was running a legit public online game because of this. I'd give this asset 6 stars if it was possible.
