Battle-tested NAT traversal
Give every session a proven fallback path for restrictive NATs, mobile carriers, VPNs, and enterprise firewalls.
Xirsys gives real-time apps a battle-tested STUN/TURN API for WebRTC NAT traversal, voice, video, and data. Use our global TURN server cloud with browser WebRTC, native clients, media servers, calling SDKs, or AI voice/video agents without handing over your app layer.
Xirsys is not another calling SDK. It is the neutral connectivity layer underneath: WebRTC NAT traversal, standards-based credentials, global relay routing, and proven fallback paths for real-world networks.
Give every session a proven fallback path for restrictive NATs, mobile carriers, VPNs, and enterprise firewalls.
Use standard ICE server configuration with browser WebRTC, native clients, third-party frameworks, calling SDKs, or your own media servers.
Issue temporary credentials through the API or keep static non-expiring TURN credentials for media servers, AI agents, and long-running infrastructure.
Whether a session starts in a browser, native app, media server, or AI workflow, paid plans can route TURN selection around the end user's location across the full production network.
All paid plans include all 12 production regions behind the same API.
User-geo routing keeps TURN selection aligned with the end user's location, even when the backend is elsewhere.
Flat-rate regional access keeps scaling predictable across geography.
Multiple channels separate apps, environments, or customers for individual usage reports.
Use Xirsys anywhere you need low-friction real-time media or data connectivity: embedded support, collaboration, telehealth, live streaming, voice agents, video agents, and custom WebRTC platforms.
Direct STUN traffic stays free, and paid bandwidth is reserved for TURN-relayed sessions that actually need help crossing networks.
Keep your preferred client, SDK, model provider, or media server while Xirsys handles the relay layer underneath.
Paid plans add dashboard-managed static credentials for trusted infrastructure while the API can issue temporary credentials for dynamic clients, services, and agent sessions.
Prototype with the developer account, then move to a paid plan for all 12 regions, user-geo routing, static credentials, multiple channels with individual usage reports, higher WebSocket concurrency, and clear TURN bandwidth pricing.
