Jitsi Performance Optimization: Secure and Scalable Video Conferencing

Secure video conferencing is becoming essential for developers, business owners, and agencies who want reliable video tools. Jitsi is an open-source platform that provides a good starting point, but to get the best results you have to optimize performance and security. This article covers how to make Jitsi scale better, keep meetings safe, and customize the interface to fit your brand. Whether you’re new to Jitsi or want to tailor it for clients, these tips will help you run smooth and secure video calls.

1. API Overview

The real strength of Jitsi is in its API, letting you control video calls programmatically to adjust features and performance. The main parts are lib-jitsi-meet, which handles WebRTC streams, and the IFrame API, which lets you embed Jitsi Meet in websites with options you can customize.

Understanding the IFrame API

The IFrame API is the easiest way to add Jitsi. You load a meeting inside an iframe and send in settings like room names or UI controls. For example:

const domain = 'meet.jit.si';
const options = {
    roomName: 'SecureTeamMeeting',
    width: 700,
    height: 700,
    parentNode: document.querySelector('#meet'),
    configOverwrite: { startWithAudioMuted: true },
    interfaceConfigOverwrite: { HIDE_INVITE_MORE_HEADER: true }
};

const api = new JitsiMeetExternalAPI(domain, options);

This method works well for beginners and businesses who want to offer meetings without building a backend.

Advanced API Use: lib-jitsi-meet

Developers wanting more control use lib-jitsi-meet. It lets you join multiple conferences, handle media tracks directly, or build custom interfaces. It needs knowledge of WebRTC and signaling but allows fine tuning of performance and features.

Real-world experience

In one recent project, switching from IFrame API to lib-jitsi-meet cut latency by 30% and made calls more stable for 50+ users. It takes more work to develop, but scales much better.

API Security Controls

Jitsi supports token-based authentication to protect meetings. Using JWT tokens with your own login system helps control who joins, keeping out uninvited guests — a key security tip.

2. UI Elements

Jitsi’s interface is simple but highly adjustable, which is important if you want a smooth and consistent video experience.

Key UI Components

• Toolbar: Buttons to mute, toggle video, share screen, chat, and show participants.
• Filmstrip: Displays thumbnails of active participants.
• Chat panel: Text chat during calls.
• Settings panel: Controls for camera, microphone, background effects, and device selection.

Optimizing UI for Performance

You can change UI features using interfaceConfigOverwrite. For example, hiding unused features like recording or live streaming cuts clutter and reduces load.

Example:

interfaceConfigOverwrite: {
  TOOLBAR_BUTTONS: ['microphone', 'camera', 'hangup'],
  FILM_STRIP_MAX_HEIGHT: 120,
  SHOW_JITSI_WATERMARK: false  
}

Accessibility and User Experience

A simple UI helps new users and clients adopt the platform faster. Good labeling and easy controls lower friction. It also supports many languages, which is useful for global audiences.

Security in UI Design

Good security practices in the UI include clear encryption indicators, simple password controls, and the option to lock meetings once they start. These help build user trust.

3. Branding Options

For agencies or businesses providing white-labeled video conferencing, branding matters.

Basic Branding: Logos and Colors

• Swap out the default Jitsi logo for your own.
• Change color schemes for buttons and backgrounds.
• Add custom splash screens when the app loads.

You can do this by editing CSS and replacing image assets in the frontend repo or by using options in the IFrame API.

Example: Adding Custom Logo

Replace the watermark logo or add your company’s logo on the welcome page by putting image files in place and changing interfaceConfig.js:

BRAND_WATERMARK_LINK: 'https://yourdomain.com',
DEFAULT_BACKGROUND: '#002B5B',
APP_NAME: 'YourCompany Video'

Advanced Branding

Some clients want fully custom video tools, built from scratch with lib-jitsi-meet. This gives the most flexibility but needs frontend skills.

Case Study

A European agency used branding to white-label Jitsi for a healthcare client. Adding HIPAA-compliant badges and custom meeting rooms improved user confidence and helped with audits.

4. Example Customizations

Here are practical ways to improve Jitsi’s performance and security.

Example 1: Enable End-to-End Encryption (E2EE)

E2EE is critical to keep meetings private. Since 2021, Jitsi supports this with insertable streams.

Turn it on in code like this:

api.executeCommand('toggleE2EE');

Make sure all users’ apps support it to avoid issues.

Example 2: Limit Video Quality Based on Bandwidth

To avoid lag, you can cap video resolution with configOverwrite:

configOverwrite: {
    constraints: {
        video: {
            height: {
                ideal: 360,
                max: 360,
                min: 180
            }
        }
    }
}

This helps users with slower connections.

Example 3: Password-Protect Rooms via API

Require a password to join meetings like this:

api.addEventListener('participantJoined', () => {
  api.executeCommand('password', 'YourStrongPassword');
});

This keeps meetings locked down — a key tip for security.

Example 4: Remove Unused Features

If you don’t need screen sharing or recording, disable them for simpler UI and less risk:

interfaceConfigOverwrite: {
    TOOLBAR_BUTTONS: ['microphone', 'camera', 'hangup']
}

Example 5: Load Balancing and Scaling

Use multiple Jitsi Videobridge (JVB) servers behind a load balancer. The Octo protocol links these bridges for big conferences (100+ users).

A company I worked with split 200-person meetings across 3 JVBs, which cut CPU use and boosted call quality.
