Realtime Infrastructure,
Reimagined.
We believe realtime communication shouldn't be expensive, complex, or locked behind walled gardens. Cloudfort exists to give every developer — from solo indie creators to enterprise studios — the tools to build voice and realtime features in minutes, not months.
Our Mission
The realtime infrastructure landscape is dominated by a few big players who charge premium prices and lock you into their ecosystem. We're building the alternative: open, affordable, and developer-first.
Cloudfort's two products — Callum for voice and Tez for realtime networking — are designed to work together or standalone, on your cloud or ours, with SDKs that respect your time.
We're especially proud that Cloudfort is the only voice platform that natively supports both Unity (for games) and .NET MAUI (for apps) with a single backend. That's not an accident — it's by design.
Developer First
Every decision starts with "does this make the developer's life easier?" If not, we don't ship it.
Open & Transparent
Self-hostable source code, clear pricing, no lock-in. You own your infrastructure.
Performance Obsessed
Sub-10ms isn't a marketing number — it's our engineering standard. Every millisecond matters.
Accessible to All
Free tier that actually works. No credit card. No time limit. Build your prototype and show the world.
Built With the Right Tools
We chose every piece of our stack for performance, reliability, and developer experience.
The Story
Cloudfort started with a simple frustration: integrating voice chat into a game or app shouldn't require a PhD in networking or a five-figure monthly bill. The existing solutions were either prohibitively expensive, too complex to set up, or both.
We set out to build what we wished existed: a voice and realtime platform that a solo developer could integrate in an afternoon, and that a studio could scale to millions of users without migrating to a different system.
The result is Cloudfort — a suite of realtime infrastructure products built on modern protocols (UDP, Opus, Rust) with a developer experience that respects your time. Whether you're building a multiplayer game in Unity, a collaboration app in MAUI, or something we haven't even thought of yet — we've got your backend covered.
