Video Conferencing APIs: The Complete Developer Guide to Choosing and Using the Right One

Video conferencing APIs play a key role when you want to add real-time communication to your app or product. If you’re working with Jitsi or looking at other options, picking the right API is a decision that affects scalability, customization, and cost for years.

Let’s break down the video conferencing API landscape with practical insights so you can weigh the trade-offs between hosted and self-hosted approaches more clearly.

Why Your API Choice Matters for the Long Term

Choosing a video conferencing API is a foundational decision. It influences the user experience, how your costs grow with scale, and how flexible your features can be.

Say you’re building a telehealth app. Strict data privacy and compliance push you toward a self-hosted setup like Jitsi or a hosted provider that meets regional regulations. On the other hand, if you run a learning management system with varying class sizes, you might prefer hosted APIs that scale easily and offer simple integration.

Your choice defines:

• How much you can customize UI and workflows
• The overhead of maintaining servers and infrastructure
• Whether you pay per minute of usage or fixed server costs
• Access to features like SIP integration, recording, analytics
• Control over security measures and compliance

Reversing your decision later isn’t easy. Make sure the API fits both your technical needs and business goals from the start.

Understanding Hosted and Self-Hosted Video APIs

Video conferencing APIs usually fall into two buckets: hosted and self-hosted.

Hosted APIs come from providers like Agora, Twilio, and Daily.co. They manage signaling, media relay, and server scaling on your behalf. You get APIs and SDKs to embed video chat quickly without worrying about infrastructure. Their pricing is usually usage-based, often charging per participant-minute.

Self-hosted APIs like Jitsi require you to run and maintain your own servers or cloud instances. You keep full control over data and can customize extensively, but you’re responsible for uptime, scaling, and security.

Comparing the Two

• Development speed: Hosted APIs let you launch faster with less setup. Self-hosted requires provisioning servers and some infrastructure know-how.
• Scalability: Hosted providers handle bandwidth and capacity automatically. Self-hosted needs deliberate planning and possibly clustering.
• Customization: Self-hosted options enable deep UI and workflow changes. Hosted APIs often limit customization to certain parameters.
• Cost: Hosted charges scale with usage, which is handy at low volumes but costly when traffic spikes. Self-hosted means server and maintenance costs but may become cheaper over time if usage is steady.
• Compliance: Self-hosting lets you control where and how data stays, crucial for healthcare or regulated sectors. Hosted solutions need certification review before use.

Using Jitsi’s IFrame API for Quick Embedding

The Jitsi IFrame API lets you embed a video conference inside a webpage or app with minimal effort and no backend integration.

When to Use It

• You want fast embedding without backend signaling
• You don’t need much customization beyond branding or room names
• Suitable for small events or internal tools that don’t require deep feature control

How to Set It Up

Here’s how to embed a room called “DevTeamRoom”:

const domain = 'meet.jit.si';
const options = {
    roomName: 'DevTeamRoom',
    parentNode: document.querySelector('#jitsi-container'),
    configOverwrite: { startWithAudioMuted: true },
    interfaceConfigOverwrite: { SHOW_JITSI_WATERMARK: false },
};

const api = new JitsiMeetExternalAPI(domain, options);

This launches the conferencing widget inside a target DOM element. You can listen for events and send commands through the api object.

What It Doesn’t Do

The IFrame API limits you to Jitsi’s default UI and features. If you want a custom user experience, this approach falls short. Also, it depends on the hosted meet.jit.si server unless you host Jitsi yourself, which may be a concern for data control.

lib-jitsi-meet: For Advanced Customization and Full Control

If your app demands more control over media, signaling, and UI, lib-jitsi-meet is the way to go.

What It Offers

• Direct access to media streams, ICE, signaling, and device controls
• Ability to build custom UI layouts and video controls from scratch
• Programmatic management of joining rooms, muting, and backend integrations

Real Use Case

Imagine a telehealth platform that needs tight integration with patient records and compliance tracking. lib-jitsi-meet lets developers add custom authentication, role-specific layouts (doctor vs patient), and plug in live transcription.

How to Initialize lib-jitsi-meet

const options = {
    hosts: {
        domain: 'meet.jit.si',
        muc: 'conference.meet.jit.si',
    },
    serviceUrl: 'wss://meet.jit.si/xmpp-websocket',
    clientNode: 'http://jitsi.org/jitsimeet',
};

const connection = new JitsiMeetJS.JitsiConnection(null, null, options);

connection.addEventListener(
    JitsiMeetJS.events.connection.CONNECTION_ESTABLISHED,
    () => console.log('Connection established')
);

connection.connect();

This snippet establishes a WebSocket connection to the server. From there, you join rooms, control streams, and handle signaling.

What You Should Know

lib-jitsi-meet requires deeper WebRTC and signaling knowledge. Without that expertise, integration may slow down. Also, to maintain data control, you’ll need to self-host or use managed deployments.

Hosted APIs: Agora, Twilio, Daily.co Explained

Popular hosted providers give you SDKs and REST APIs to embed video conferencing easily.

What You Get

• Global server infrastructure for low latency worldwide
• Managed signaling and media servers simplifying WebRTC complexity
• Features like recording, real-time transcription, analytics, and moderation dashboards
• SDKs for web, iOS, Android with consistent API sets

Pricing Overview

They usually charge based on participant time or active minutes. Usage-based pricing scales well but can add up fast, especially for large or long meetings. Enterprise deals with flat fees may be available but require negotiation.

In contrast, self-hosted Jitsi runs on fixed infrastructure costs but demands operational effort.

Example Integrating Twilio Video

import { connect } from 'twilio-video';

connect('token', { room: 'DailyStandup' })
  .then(room => {
    console.log(`Connected to Room: ${room.name}`);
    room.participants.forEach(participant => {
      console.log(`Participant: ${participant.identity}`);
    });
  })
  .catch(error => {
    console.error(`Unable to connect: ${error.message}`);
  });

This code shows a straightforward connection with a backend-generated token.

Considerations

• Hosted APIs may restrict signalling customization and risk vendor lock-in.
• Costs increase with usage; big teams or long events get expensive.
• Feature sets vary, especially for things like recording and analytics.
