Meetings, group and one-to-one calls, classrooms, audio rooms, live streams and AI agents, on one platform with one token flow.

Start free: 10,000 minutes

One platform and one set of SDKs for every real-time moment in your app: Video meetings and classes, Voice calls and rooms, Live streams, AI agents that join the conversation, a Beauty filter included free, and Studio to design the look.

From sign-up to a liveroom in three steps

No media servers to run. You keep control of who joins, because every join needs a token from your own server.

  1. Create a project

    Sign in to the Gravix Cloud console and create a project. You get an App ID and an App Certificate. The App Certificate stays on your server.

  2. Issue tokens from your server

    When a user joins, your backend signs a short-lived access token for that user and that room. Your app never sees the secret.

  3. Join from your app

    The SDK fetches the token from your backend and joins the room. Each person connects through a region near them.

join_room.dart (Flutter)
import 'package:gravix_rtc/gravix_rtc.dart';

final room = GravixRoomService();

final tokens = GravixTokenProvider.endpoint(
  Uri.parse('https://api.example.com/rtc/token'),
  headers: {'Authorization': 'Bearer $session'},
);

final ok = await room.connectWithTokenProvider(
  tokenProvider: tokens,
  request: GravixTokenRequest(room: roomId, identity: uid, name: name),
  publishMic: true,
  enableVideo: true,
);

The token comes from your server. Never put the App Certificate in app code.

Flutter and Web.One token flow.

Build Android and iOS apps with Flutter and web apps with the Web SDK. Both join the same rooms, so an Android user, an iOS user and a web user can be in one call.

Built forglobal real-time

Conversations feel natural when the route is short. Gravix Cloud handles the routing, so your users just talk.

  • A region near each person

    Each person connects through a region close to them, and media takes a short route between participants.

  • Quality that adapts

    Video is sent in several quality layers, so each viewer gets the best picture their connection can carry.

  • Encrypted in transit

    Audio and video are encrypted between devices and the platform with DTLS-SRTP.

  • Tokens from your server

    Every join needs a short-lived token that your backend issues. Nobody gets in without one.

Questions,answered

Anything else? Call or WhatsApp us and a person will answer.

What is Gravix Cloud?

Gravix Cloud is a real-time communication platform for app developers. It gives your app voice calls, video calls and meetings, online classes, live audio rooms, live streaming and AI voice and video agents through SDKs, so you do not have to build or run your own media infrastructure.

How do I add voice or video calling to my app?

Create a project to get your App ID and App Certificate, issue a short-lived access token for each user from your own server, then join a room with the Gravix Cloud SDK in your app. The SDK connects each user to a nearby region and handles audio and video for you.

Which platforms do the Gravix Cloud SDKs support?

Gravix Cloud provides SDKs for Flutter and Web. The Flutter SDK is published as gravix_rtc.

Does my secret key go inside the app?

No. Your secret stays on your server. Your server issues a short-lived access token for each user and room, and the app only ever receives that token.

Can I build video meetings and online classes?

Yes. Team meetings, group calls, one-to-one calls and live classes all run on the same rooms and SDKs. People can share their screen, calls and classes can be recorded in the cloud, and the host can mute or remove participants. Video is sent in several quality layers, so each person gets the best picture their connection can carry.

Can I build live audio rooms with hosts, speakers and listeners?

Yes. Audio rooms are a core use case: hosts and speakers talk while a large audience listens, and you can move people on and off stage in real time.

What are AI voice agents and AI video agents?

They are AI participants that join a call or room like a person would. A voice agent listens and talks back, for example as a support assistant or room host. A video agent also appears on camera, for example as a tutor or presenter.

Is the beauty filter really free?

Yes. The Gravix real-time beauty filter is included free with a Gravix Cloud subscription. It adds skin smoothing, tone and colour grading, face shaping and makeup effects to live video on Android and the web, with a Flutter plugin.

What is Gravix Studio?

Gravix Studio is an editor that runs in your browser for creating beauty and camera looks. You design a look with tone, face shaping, colour grades, makeup, stickers and captions, preview it live on your camera, a video or a photo, and export a single look file that the Gravix beauty filter renders in your app.

How much does Gravix Cloud cost?

Starter is $1 per 2,000 minutes. Professional is $200 per 150 concurrent participants. Enterprise is $7,999 per year, terms and conditions apply. Contact sales for a custom plan.

Can I try Gravix Cloud first?

Yes. Every new account gets 10,000 free minutes when you sign up, so you can build and test calls on your own network before you pay.
