Real-time Network Engine That Scales

Get Started

Increasing Real-Time Communication Needs and Challenges

In recent years, we are witnessing the increase of services and technologies such as autonomous driving, IoT devices, and VR etc. that are focusing on large-scale concurrent connection and real-time communication.
However, providing robust and maintainable system has been a technical challenge for many companies and their services.

With 5G, you will be able to achieve roughly 10 times more concurrent connections.
Our network infrastructure has been improving so that events with thausands of participants have almost no network connectivity issues.
We are expecting to see more interactive services with technologies such as VR/AR etc.

For latency-sesitive systems such as autonomous driving etc., if we could use low-latency communication that exchange the data from sensors of connected vihecles, the ability of the system will improve dramatically.
Moreover, auto industry is now looking at bringing in the entertainment to our every day vihecles, and having scable real-time network communication is becoming even more important.

Diarkis enables you to build the critical component for all of these new systems.
Diarkis supports all major network protocols: TCP, UDP, RUDP, WebSocket, and HTTP and its client SDK supports crossplatform engine such as Unity etc. In addition to relay-based communication, Diarkis also allows communication via P2P (peer-to-peer) orver UDP in order for clients to connect directly.

Our Technology

Diarkis is our own engine that provides real-time network-based communications over TCP, UDP, RUDP, and WebSocket as well as HTTP protocol.
Diarkis also enables its clients to communicate directly via P2P (peer-to-peer) over UDP for least amount of latency and combines it with server-to-client relay commnunication extending the ability to create both fast and massive network communication for your applications.
Diarkis is designed to scale automatically according to your application network traffic without halting the service at all.
Decentralized design of Diarkis' internal core provides fault-tolerance and reliability that your application needs.

Diarkis also provides you with client SDK. For TCP and UDP, RUDP, and P2P, we have ready-to-use Unity compatible C# SDK and C++ SDK with Unreal Engine support is on the way.
For WebSocket, we have javascript SDK.

Auto-Scalable Architecture

Diarkis is designed to scale without adding or changing any of your application configurations or code.
This architecture also allows Diarkis to deploy without stopping your application process to allow seamless updates.


Decentralized design of Diarkis makes your application extremely resilient against server failures and other unexpected problems.
If one or more server instances fail, other instances are able to step in to fill in the gap and your application will never know if anything at all happened.

Ready To Use Modules

Diarkis provides you with plethora of modules to aid your application development.
Creating chat rooms, match making, and more are avilable along with Diarkis client SDK.

Unparalleled Performance

Diarkis' innovative engineering gives performance effeciency and best performance per CPU.
Performance is one of our main focus and we take it seriously. Diarkis is fine-tuned to output the best performance in any situation.
