Mirror is a high level Networking API for Unity, built on top of the low level Telepathy library.
Mirror is optimized for ease of use and probability of success. Projects that use Mirror are small, concise and maintainable. uMMORPG was possible with <6000 lines of code. We needed a networking library that allows us to launch our games, period.
With Mirror, the Server & Client are ONE project (hence the name). Instead of having one code base for the server and one for the client, we simply use the same code for both of them.
[Client]tags can be used for the server-only and client-only parts.
[Command]are used for Client->Server, and
[TargetRpc]for Server->Client communication.
SyncLists are used to automatically synchronize state.
What previously required 10.000 lines of code, now takes 1.000 lines of code. Therein lies the magic of Mirror.
Note: Mirror is based on Unity's abandoned UNET Networking system. We fixed it up and pushed it to MMO Scale.
The main difference is that you have to use
using Mirror; instead of
using UnityEngine.Networking; at the top of your scripts.
If you are coming from a current UNET implementation or are seeking the stable version:
Import mirror from the Asset Store into your project.
Alternatively, you can install new releases manually:
Note: New releases are bleeding edge and may come with undiscovered bugs. Use at your own risk!
- Download Mirror (for Unity 2018.2.20 or 2018.3.x).
- Decompress the zip file in Assets
If you are still using UNET and want to switch to Mirror, you should check out our Migration Guide. Don't panic, it's very easy and won't take more than 5 minutes.
Download Mirror from the Asset Store, we have several small example projects included.
If you don't want to use Telepathy or UNET's LLAPI as low level transport, then check out:

Mirror is developed by volunteers. If you like what we are doing, consider leaving a small donation.
- Telepathy 1000 connections test
- uMMORPG 480 CCU worst case test (everyone broadcasting to everyone else)
- uSurvival 122 CCU worst case test
We follow the KISS principle, so make sure that your Pull Requests contain no magic.
We need Mirror to be MMO Scale. Bug fixes are always highly appreciated. New features will be considered very carefully.
