Why Cloudfort

Built Different. Built Better.

We obsess over the details so you can focus on building great experiences.

Ultra-Low Latency

Pure UDP transport with Opus codec delivers sub-10ms voice latency. Your players hear each other in real-time, not real-slow.

5-Minute Integration

Drop-in SDKs for Unity, .NET, Java, Swift, Unreal, Flutter, and React Native. Install, add your API key, and you're live. No boilerplate, no config hell.

Self-Hostable

Full backend binary or source code available for on-prem deployment. Your data, your servers, your rules. Perfect for regulated industries.

7 SDKs, One Backend

Native SDKs for Unity, .NET, Java, Swift, Unreal, Flutter, and React Native — all powered by a single backend. Games, mobile apps, desktop, web — every platform covered.

Crystal-Clear Audio

Opus HD codec with forward error correction. Voice sounds natural even on flaky networks. No robotic artifacts, ever.

Developer Dashboard

Real-time analytics: CCU, bandwidth, room status, and latency metrics. Know exactly how your infrastructure is performing at a glance.
