Big video conferencing setups need a solid backend that handles signaling and media well. Prosody is the XMPP server under Jitsi Meet that manages communication among clients and components. When you’re scaling from a handful of users to hundreds or thousands, tuning Jitsi Meet prosody becomes essential. Skip it, and you’ll see lag, dropped calls, or late messages.
Whether you’re just starting with Jitsi, a business owner curious about how it all works, or an agency offering white-label tools, this guide shows you how to get the best from Prosody for jitsi scaling and better prosody performance. We’ll cover the API basics, some UI tips, branding ideas, example tweaks, and point you to great resources to keep things steady and scalable.
Prosody is an XMPP server built with Lua that handles real-time messages and signaling in Jitsi Meet. When someone joins a meeting, their client talks to Prosody, which manages messaging, presence, authentication, and ties participant info with Jicofo (the conference focus) and videobridge servers that handle media.
Prosody works in modules, which you can tune for better scaling. Focus on these:
For scaling, the key is routing messages efficiently and supporting clustering or horizontal scaling. Prosody can cluster using external tools like Redis or database backends to share state.
Just throwing more CPU and RAM at one server doesn’t cut it when you have 10,000+ users. A big university switched to offloading state info to Redis (using mod_mam and mod_pubsub) and boosted message distribution by 40%. That cut down signaling delays noticeably.

Developers should watch how signaling flows:
Improving Jitsi Meet prosody UI signaling performance depends on handling backpressure properly in the messaging pipeline. That’s something you can tune at the Prosody level.
If you provide white-labeled products, syncing UI tweaks with backend improvements helps maintain performance when loads rise. For example, hold off on heavy animations until signaling confirms the participant action went through.
Prosody itself isn’t about branding, but it affects it indirectly through custom auth, domain handling, and multi-tenant support.
If you rebrand Jitsi Meet for multiple clients, Prosody lets you host several virtual domains. Each domain can stand for a client’s brand or space. This is key for white-label setups at scale.
Example:
VirtualHost "client1.example.com"
modules_enabled = { "muc", "ping" }
VirtualHost "client2.example.com"
modules_enabled = { "muc", "ping" }Each domain gets its own auth and components, which reflect different branding and user experiences on the surface.
Use external auth like OAuth or LDAP with Prosody to offer branded, seamless logins. Businesses that want control and brand consistency need this.
Branded setups must enforce TLS on Prosody, secure auth, and keep servers updated to protect privacy. Being clear about privacy and following compliance builds trust.
Customizing Prosody for large-scale Jitsi means tweaking configs, modules, and hooking into system behavior.

One university running 1000+ simultaneous calls built a custom Prosody module that changed resource limits during peak times and sent alerts when signaling failed. This helped avoid outages.

Optimizing Jitsi Meet prosody is key for large deployments. You get reliable signaling, lower latency, and better user experience even under heavy load. Knowing the APIs, managing UI signaling, supporting multi-domain branding, and tuning performance customizations lays a solid base for scaling.
Whether you’re new, running a business, or an agency, putting effort into prosody tuning pays off with smoother calls and happier users. Keep security and trust top of mind when customizing or scaling real-time tools.
Next step: audit your Prosody setup, spot bottlenecks, and apply these tuning tips. Stay connected to official docs and the community to keep your deployment solid and ready for what’s next.
Jitsi Meet prosody is the XMPP server that manages signaling and real-time communication. It's the backbone for secure, scalable video calls.
Improve performance by tuning prosody’s modules, optimizing database use, enabling clustering, and scaling resources properly.
Typical issues include resource bottlenecks, message routing delays, bad clustering setups, and configs that cause call drops or lag.
Yes, but prosody optimization focuses on backend performance. UI and branding changes are done separately and complement backend tuning.
