Jitsi is an open-source video conferencing platform popular with developers and businesses for flexible, scalable communication. Knowing Jitsi architecture helps you see how its main parts work together to keep video calls smooth. Whether you’re new to Jitsi, running a business considering video tools, or an agency reselling white-label platforms, this article explains the system, UI parts, branding options, and how to customize it all. Plus, you’ll get links to helpful resources.
Jitsi’s core strength is its APIs, which make it flexible for all sorts of uses. At the base, Jitsi relies on WebRTC—a protocol set that streams video and audio directly in browsers without needing plugins. The design focuses on signaling, routing media, and client-server talk.
Jitsi Meet API
A JavaScript API you use to embed Jitsi meetings in web or mobile apps. It helps developers build meeting screens, control who does what, manage streams, mute audio/video, and tweak meeting settings by code.
For example, you could put a Jitsi meeting right inside a company intranet and control features like recording or chat visibility.
Jitsi Videobridge REST API
Videobridge acts as a selective forwarding unit (SFU), sending video streams to everyone without mixing them. The REST API lets admins check bridge health, control conference quality, and gather stats to improve performance.
Jicofo (Jitsi Conference Focus)
Jicofo handles signaling and manages participants, allocating resources and tracking call state. It usually doesn’t expose APIs but plays a key role in keeping calls running smoothly.
Looking at the whole system, the client talks to Jicofo for signaling. Meanwhile, media streams go through Videobridge. The JavaScript API handles user controls and toggles features. Server parts take care of scaling and stability. This setup means you can build custom frontends but still rely on stable backend routing.
A healthcare provider recently used the Jitsi Meet API to add video calls securely to their patient portal. They added API hooks to disable recording when needed for HIPAA compliance and switched on end-to-end encryption for trusted network sessions. This shows how the API isn’t just tech but also helps meet compliance and user needs.
Jitsi Meet’s interface is simple and clear but fully customizable. The UI has:
All these parts are modular, built with React and Redux, so you can add or remove features easily.
You can change React source code or tweak config files (interfaceConfig.js and config.js). Example tweaks:
UI customization usually happens alongside API tweaks to make sure the design matches the features you want enabled or disabled.
Several agencies reselling white-label video platforms have styled themes that fit their clients’ branding. Changing colors, fonts, or control layouts helps make the experience look like part of their products—not just an open-source add-on.
Branding matters a lot if you’re using Jitsi as a white-label tool. You want users to see your brand, not just Jitsi’s default style. Jitsi supports:
Static Branding: Replace logos, splash screens, colors, and fonts by changing build files. This needs a rebuild but gives you full control.
Dynamic Branding: Swap logos or tweak colors using interfaceConfig.js and config.js without rebuilding. Great if you run a SaaS and serve multiple brands from one codebase.
If you white-label Jitsi, be upfront about the use of open-source components when licenses require it (like Apache 2.0). Also, make sure your branding meets data privacy rules by telling users how you handle their info.
Customizations can be small or large:
Feature Toggles via API
Turn off recording or live streaming for privacy-focused meetings. Like a law office that bans session recording—API handles that live.
Adding Custom UI Buttons
Some clients add buttons to trigger other apps, like opening a helpdesk ticket or launching a poll. Jitsi’s modular UI lets you plug in React components and connect them to backend APIs.
Language Localization
Jitsi supports translations, but you can add regional dialects or field-specific terms for a better fit.
Embedding in Native Apps
Businesses build mobile apps embedding Jitsi SDK with their own UX, mixing authentication and user management with video calls.
A consultancy integrated Jitsi into their client portal for video coaching. They highlighted coaches’ profiles during calls, added a “session notes” sidebar linked to CRM, and changed branding to match client dashboards. They saw 40% more engagement and fewer issues with users switching platforms.
