Voice & Video
1:1 and group calls up to broadcast scale.
WebRTC SFU built on LiveKit, tuned for mobile networks. Adaptive simulcast, dynacast and hardware acceleration keep calls crisp on a 3G handset and a gigabit laptop alike.
The self-hosted CPaaS

you actually own.
suryacloud is the self-hosted alternative to Agora and ZEGOCLOUD. One SDK for calls, chat, live streaming and recording — running on your own cloud, at roughly half the price.

The platform
Every real-time primitive, one SDK
Calls, ringing, chat, streaming and recording — designed to work together and learned once. Mix what you need; ignore the rest.
Call Invitations
Ring real phones — even when the app is closed.
A full signalling layer over WebSockets with push-triggered ringing through FCM and Apple CallKit. Invitations, accept/reject, timeouts and busy states are handled for you.
Prebuilt Call UI
Drop in a full call screen in an afternoon.
Batteries-included call views for Flutter and Web — grid & spotlight layouts, PiP, mic/camera/speaker controls, mirroring, and hang-up wired to the SDK. Theme it or fork it.
Persistent Chat
1:1 and group messaging with history.
Realtime messaging with delivery, unread counts, typing indicators, read receipts and paginated history — sharing the same connection as your calls, so there's one socket to manage.
Live Streaming
Go from a call to a stadium-scale broadcast.
Promote any room to an RTMP/HLS broadcast for audiences of thousands. Ingest from OBS or a phone, egress to HLS, and pull viewers in at a fraction of streaming-CDN cost.
Recording
Compliant recordings, straight to your bucket.
Server-side composite or track recording via egress, written directly to S3-compatible storage you control. Nothing leaves your account — ideal for regulated telehealth and fintech.
Developer experience
From npm install to a ringing phone in minutes
An API small enough to hold in your head. The same calls work in Flutter, Web and React Native — no rewrites between platforms.

A control plane, not just a connection
The pieces a real product needs around media — tenancy, keys, metering, residency — are built in. The same panel we run in production ships with the platform.
Multi-tenant control plane
Projects, API keys, per-tenant quotas and rotation — the same panel we run in production.
Usage metering & billing
Every participant-minute metered at the edge, with exportable usage for your own invoicing.
Data residency by default
Media and recordings stay in the region and account you deploy to. No third-party hop.
Token-based auth
Your backend mints short-lived session tokens with an API key. Users never see a secret.
SDKs that match
One identical API across Flutter, Web and React Native. Learn it once, ship everywhere.
Deploy in a day
Docker Compose to a single VM, or Kubernetes for scale. You hold the keys the whole way.
Deploy in a day, not a quarter
One Docker Compose file brings up the SFU, signalling and control plane on a VM you own. Point a subdomain at it and you're taking real calls — with every byte of media staying inside your account.
your-vm ~ deploy
$ docker compose up -d
✓ control-plane started
✓ signalling started
✓ sfu (livekit) started
● live at cloud.yourco.com — you own every byte
The honest comparison
Everything the big vendors do — on infrastructure you own
Same features. Better data control. A fraction of the per-minute cost. Here's the side-by-side.

How it works
From zero to a connected call in four steps
No black boxes. You can trace a call from your backend token all the way to media flowing through your own SFU.
01
Deploy the stack
One Docker Compose file brings up the SFU, signalling and control plane on a VM you own. Point a subdomain at it and you're live.
02
Mint a session token
Your backend calls /v1/session with an API key and gets back a short-lived user token. Secrets never touch the client.
03
Connect & ring
The SDK opens one socket for calls and chat. invite() rings the other user — on a real, locked phone if they're offline.
04
Media flows peer-to-SFU
Accepted calls join a LiveKit room. Tracks are simulcast to the SFU and fanned out, adapting to each viewer's bandwidth.
Proof, not promises
Teams that swapped their vendor for their own stack
Real products running calls, chat and offline ringing on suryacloud today.
We swapped ZEGOCLOUD for suryacloud in a weekend. Calls ring on locked phones, chat rides the same socket, and our comms bill dropped by an order of magnitude.

Recordings write straight to our own bucket, so compliance stopped being a blocker. The self-hosted deploy took an afternoon.

One API across Flutter and Web meant our mobile and web teams shipped calling the same week. That never happens.
