If you are building a WebRTC app, you are not just choosing a video SDK, You are choosing the infrastructure that will affect call quality, latency, recording, transcription, live streaming, mobile support, developer speed, and long-term scaling.
Most teams evaluate platforms like VideoSDK, Agora, Twilio, and LiveKit when building real-time video or audio features. However, the right choice depends on what your product needs beyond a basic video call.
Here are the key factors that help in choosing the right real-time communication API for a WebRTC app:
1. Cross-platform SDK support
A good RTC API should work across the platforms your users already use.
For most WebRTC products, that means support for:
- JavaScript
- React
- React Native
- Android
- iOS
- Flutter
- Backend or REST APIs
This is one area where VideoSDK is useful because it provides SDKs across web, mobile, and backend environments. If your product roadmap includes web today and mobile later, choosing an API with strong cross-platform support helps avoid rebuilding the communication layer again.
2. Managed infrastructure instead of WebRTC complexity
WebRTC is powerful, but production WebRTC is not simple.
You need to think about:
- Media routing
- SFU architecture
- Participant events
- Network changes
- Device permissions
- Browser behavior
- Call quality
- Recording
- Scaling
A managed RTC API like VideoSDK helps teams focus on the product experience instead of operating the full media infrastructure themselves. This is especially useful if your team wants to build custom video calls, in-app voice, customer support video chat, live streaming, or video collaboration without spending months on infrastructure.
3. Built-in production features
A basic video SDK may help you start a call. A production-ready RTC API should support the full workflow around that call.
Look for features like:
- Group video calls
- Screen sharing
- Recording
- Transcription
- HLS streaming
- RTMP streaming
- End-to-end encryption
- Participant controls
- Webhooks
- Monitoring and debugging
VideoSDK fits well here because it is not limited to simple audio/video calling. It also supports recording, transcription, HLS, RTMP, E2EE, SIP Connect, and real-time communication workflows that developers usually need after the first version of the app is live.
4. Developer experience and quickstart quality
The best real-time communication API for live video apps should be easy to test quickly.
Before choosing any platform, consider:
- How easily you can create a room
- How quickly you can join a meeting
- Whether mic and camera controls are straightforward
- How participants are rendered
- The clarity of documentation
- Availability of working examples
VideoSDK’s React quickstart is useful because it follows a simple flow that makes it easy for developers to move from evaluation to implementation.
5. Pricing and scaling clarity
When evaluating pricing for real-time video APIs, it is important to look beyond the base video minute cost.
A real WebRTC app may also involve:
- Recording usage
- Transcription
- Storage
- Streaming (HLS or RTMP)
- TURN usage
- Analytics
- Mobile SDK support
- Enterprise-level features
The right API is not always the cheapest one on paper. It is the one that provides predictable costs aligned with your actual product usage and growth.
Implementing a WebRTC call with the VideoSDK React Quickstart
Once you know what to look for in a real-time communication API, the next step is to test how fast you can actually build with it.
App Architecture
Prerequisites
Before proceeding, ensure that your development environment meets the following requirements:
- VideoSDK Developer Account (If you don’t have one, create it from the VideoSDK Dashboard)
- Basic understanding of React
- Familiarity with React VideoSDK
- Node.js and NPM installed on your device
- Basic understanding of React Hooks (
useState,useRef,useEffect) - React Context API (optional)
Token Generation
Token is used to create and validate a meeting using API and also initialise a meeting.
Important: One should have a VideoSDK account to generate a token. Visit the VideoSDK dashboard to generate your token.
VideoSDK’s React quickstart follows a simple flow:
- Create a React app
- Install the VideoSDK React SDK
- Create an
API.jsfile for room creation - Add
MeetingProvider - Create a join screen
- Add meeting controls
- Render participants
Let’s walk through the same quickstart flow.
Step 1: Create a React app
npx create-react-app videosdk-rtc-react-app
cd videosdk-rtc-react-app
Step 2: Install VideoSDK
Install the VideoSDK React package.
npm install "@videosdk.live/react-sdk"
For participant video rendering, also install react-player.
npm install "react-player"
Your basic project structure will look like this:
root
├── node_modules
├── public
├── src
│ ├── API.js
│ ├── App.js
│ ├── index.js
Step 3: Create API.js
Create a file named API.js inside the src folder.
This file will handle the API call for creating a new VideoSDK room.
// API.js
//This is the Auth token, you will use it to generate a meeting and connect to it
export const authToken = "<Generated-from-dashbaord>";
// API call to create a meeting
export const createMeeting = async ({ token }) => {
const res = await fetch(`https://api.videosdk.live/v2/rooms`, {
method: "POST",
headers: {
authorization: `${authToken}`,
"Content-Type": "application/json",
},
body: JSON.stringify({}),
});
//Destructuring the roomId from the response
const { roomId } = await res.json();
return roomId;
};
For production, do not expose the auth token directly in the frontend. Generate the token from your backend or use a backend endpoint to create rooms securely.
Step 4: Wire App.js with VideoSDK components
In App.js, import the VideoSDK React SDK components and hooks.
You will use:
MeetingProvideruseMeetinguseParticipant-
VideoPlayer
// App.js
import "./App.css";
import React, { useEffect, useMemo, useRef, useState } from "react";
import {
MeetingProvider,
MeetingConsumer,
useMeeting,
useParticipant,
VideoPlayer,
} from "@videosdk.live/react-sdk";
import { authToken, createMeeting } from "./API";
function JoinScreen({ getMeetingAndToken }) {
return null;
}
function ParticipantView(props) {
return null;
}
function Controls(props) {
return null;
}
function MeetingView(props) {
return null;
}
function App() {
const [meetingId, setMeetingId] = useState(null);
//Getting the meeting id by calling the api we just wrote
const getMeetingAndToken = async (id) => {
const meetingId =
id == null ? await createMeeting({ token: authToken }) : id;
setMeetingId(meetingId);
};
//This will set Meeting Id to null when meeting is left or ended
const onMeetingLeave = () => {
setMeetingId(null);
};
return authToken && meetingId ? (
<MeetingProvider
config={{
meetingId,
micEnabled: true,
webcamEnabled: true,
name: "C.V. Raman",
}}
token={authToken}
>
<MeetingView meetingId={meetingId} onMeetingLeave={onMeetingLeave} />
</MeetingProvider>
) : (
<JoinScreen getMeetingAndToken={getMeetingAndToken} />
);
}
export default App;
MeetingProvider gives the child components access to meeting state, participant data, and meeting controls.
Step 5: Create the JoinScreen component
The join screen lets a user create a new meeting or join an existing meeting ID.
function JoinScreen({ getMeetingAndToken }) {
const [meetingId, setMeetingId] = useState(null);
const onClick = async () => {
await getMeetingAndToken(meetingId);
};
return (
<div>
<input
type="text"
placeholder="Enter Meeting Id"
onChange={(e) => {
setMeetingId(e.target.value);
}}
/>
<button onClick={onClick}>Join</button>
{" or "}
<button onClick={onClick}>Create Meeting</button>
</div>
);
}
Output
If the input is empty, a new meeting is created. If a meeting ID is entered, the user joins that meeting.
Step 6: Create MeetingView and Controls
MeetingView handles the meeting state. It lets the user join the meeting and renders the participants once the meeting is joined.
function MeetingView(props) {
const [joined, setJoined] = useState(null);
//Get the method which will be used to join the meeting.
//We will also get the participants list to display all participants
const { join, participants } = useMeeting({
//callback for when meeting is joined successfully
onMeetingJoined: () => {
setJoined("JOINED");
},
//callback for when meeting is left
onMeetingLeft: () => {
props.onMeetingLeave();
},
});
const joinMeeting = () => {
setJoined("JOINING");
join();
};
return (
<div className="container">
<h3>Meeting Id: {props.meetingId}</h3>
{joined && joined == "JOINED" ? (
<div>
<Controls />
//For rendering all the participants in the meeting
{[...participants.keys()].map((participantId) => (
<ParticipantView
participantId={participantId}
key={participantId}
/>
))}
</div>
) : joined && joined == "JOINING" ? (
<p>Joining the meeting...</p>
) : (
<button onClick={joinMeeting}>Join</button>
)}
</div>
);
}
Now add the meeting controls.
function Controls() {
const { leave, toggleMic, toggleWebcam } = useMeeting();
return (
<div>
<button onClick={() => leave()}>Leave</button>
<button onClick={() => toggleMic()}>toggleMic</button>
<button onClick={() => toggleWebcam()}>toggleWebcam</button>
</div>
);
}
Output of Controls Component
With this, the user can join, leave, mute/unmute the mic, and turn the webcam on/off.
Step 7: Implement Participant View
Before implementing the participant view, you need to understand a couple of concepts.
- Forwarding Ref for mic
The useRef hook is responsible for referencing the audio component. It will be used to play and stop the audio of the participant.
const micRef = useRef(null);
- useParticipant Hook
The useParticipant hook is responsible for handling all the properties and events of one particular participant joined in the meeting. It will take participantId as argument.
const { micStream, webcamOn, micOn } = useParticipant(props.participantId);
- MediaStream API
The MediaStream API is beneficial for adding a MediaTrack to the audio tag, enabling the playback of audio.
const micRef = useRef(null);
const mediaStream = new MediaStream();
mediaStream.addTrack(micStream.track);
micRef.current.srcObject = mediaStream;
micRef.current
.play()
.catch((error) => console.error("micElem.current.play() failed", error));
Note: Only use the MediaStream API for microphone access. The VideoPlayer component in VideoSDK automatically handles the video stream.
Now you can use both of the hooks and the API to create ParticipantView.
function ParticipantView(props) {
const micRef = useRef(null);
const {micStream, webcamOn, micOn, isLocal, displayName } =
useParticipant(props.participantId);
useEffect(() => {
if (micRef.current) {
if (micOn && micStream) {
const mediaStream = new MediaStream();
mediaStream.addTrack(micStream.track);
micRef.current.srcObject = mediaStream;
micRef.current
.play()
.catch((error) =>
console.error("videoElem.current.play() failed", error)
);
} else {
micRef.current.srcObject = null;
}
}
}, [micStream, micOn]);
return (
<div>
<p>
Participant: {displayName} | Webcam: {webcamOn ? "ON" : "OFF"} | Mic:{" "}
{micOn ? "ON" : "OFF"}
</p>
<audio ref={micRef} autoPlay playsInline muted={isLocal} />
{webcamOn && (
<VideoPlayer
participantId={props.participantId} // Required
type="video"
containerStyle={{
height: "300px",
width: "300px",
}}
className="h-full"
classNameVideo="h-full"
videoStyle={{}}
/>
)}
</div>
);
}
Step 8: Run the project
Start the React app.
npm start
Now you can:
- Create a meeting
- Join a meeting using a meeting ID
- Toggle mic
- Toggle webcam
- Leave the meeting
- Render participants in the call
This gives developers a practical way to evaluate VideoSDK before building a full production WebRTC app.
