BigBlueButton vs. Plug-N-Meet: A Modern Alternative for Scalable Video Conferencing
If you're in the world of open-source education or communication, you owe a debt of gratitude to BigBlueButton. It was a pioneering platform that showed the world what was possible. However, as the web has evolved, the demands for scalability, developer experience, and cost-effective performance have grown exponentially.
Many long-time BigBlueButton users are now looking for a next-generation solution, one designed from the ground up to meet the new demands for scalability and flexibility that the modern web requires. This is where Plug-N-Meet comes in.
This article provides a direct, head-to-head comparison to help you understand the key differences in philosophy and technology, so you can make an informed decision about which platform is right for you.
At a Glance: A Head-to-Head Comparison
| Feature / Aspect | BigBlueButton (BBB) | Plug-N-Meet | Why It Matters |
|---|---|---|---|
| Core Architecture | Monolithic: Tightly coupled services (web, media, recording). | Decoupled: Independent microservices for the app, media, and recorder. | You can scale, update, or maintain one part of Plug-N-Meet without impacting the others, leading to higher stability and lower costs. |
| Technology Stack | Complex Mix: A combination of Scala, Java, JavaScript, Ruby, etc. | Unified & Modern: Go for the entire backend, TypeScript/React for the frontend. | A simpler, unified stack is far easier to maintain, debug, and contribute to, resulting in faster development cycles. |
| Media Server | FreeSWITCH & mediasoup (previously Kurento) | LiveKit (a modern, high-performance SFU) | LiveKit is purpose-built for scalable WebRTC, offering better performance, adaptive streaming (Simulcast/Dynacast), and lower resource usage out of the box. |
| Security & E2EE | Basic encryption. E2EE is not a native, fully integrated feature. | Native End-to-End Encryption (E2EE): A core, API-controlled feature with multiple key management models. | Plug-N-Meet provides true zero-trust security, ensuring not even the server can access meeting content. This is critical for privacy-sensitive applications. |
| Recording | Reconstructs a presentation from separately recorded raw streams. | High-Fidelity Capture: A headless browser records the final rendered output to a single MP4. | Plug-N-Meet's method produces a perfect, "what you see is what you get" replica of the live session, ensuring perfect synchronization. |
| Customization | Static Theming: Requires complex server-side configuration and often code modification. | Multi-Layered & Dynamic: Offers four levels of customization, from simple branding to a "headless" native integration. | Plug-N-Meet's API-driven approach enables true multi-tenant branding and a vastly superior white-label experience. |
| Installation | Scripted, but with heavy, specific OS dependencies. | Automated script using Docker containers. | Plug-N-Meet's containerized setup is faster and avoids conflicts with other services on the host machine. |
| Upgrades & Maintenance | Full Rebuild Required: OS upgrades require a new server and manual data migration. | Simple & In-Place: Docker abstracts the OS, allowing safe, independent updates. | You avoid the operational cost and risk of rebuilding your server for every major OS update. |
| Multi-Tenancy | Domain-Coupled: Difficult to serve multiple domains from one instance. | Domain-Agnostic: A single server can easily serve unlimited domains via a reverse proxy. | Greatly simplifies offering a white-labeled service to multiple clients from a single, cost-effective server instance. |
Key Difference 1: The Architectural Philosophy
The most fundamental difference is in the design philosophy.
BigBlueButton is a monolith. Its core components are tightly interwoven. This means if your recording service is consuming all the CPU, it directly impacts the performance of your live meetings.
Plug-N-Meet is built on a decoupled, microservices-based architecture. The application server, the LiveKit media server, and the recorder are all independent services. This allows you to isolate workloads and scale intelligently, leading to a significantly lower Total Cost of Ownership (TCO).
Key Difference 2: A Multi-Layered Approach to Customization
This is a game-changer for anyone building a white-label or multi-tenant service.
BigBlueButton uses a static theming approach. Customizing the look and feel is a complex, server-wide change that often requires modifying configuration files and restarting services.
Plug-N-Meet is API-first and dynamic, offering a multi-layered approach to white-labeling that allows you to choose the level of customization that fits your needs:
- Level 1: Quick Rebranding: Instantly change logos, colors, and backgrounds via a simple configuration object.
- Level 2: API-Driven Feature Control: Programmatically enable or disable features (like the whiteboard or breakout rooms) to create purpose-built experiences for different use cases.
- Level 3: Deep Styling with Custom CSS: Provide a URL to your own stylesheet for pixel-perfect control over any UI element.
- Level 4: True Native Integration: Use the
getClientFilesAPI to render the client "headless" directly within your own application, giving you complete control over the layout and user experience.
This layered flexibility makes it easy to get started but provides a path to a truly unique and deeply integrated product.
Key Difference 3: Security by Design - Native End-to-End Encryption
BigBlueButton's architecture requires the server to have access to unencrypted media streams for features like recording. This architectural choice is incompatible with a zero-trust E2EE model.
Plug-N-Meet was built with a "privacy by design" philosophy. E2EE is a core, native feature of the platform. As detailed in our Security Overview, we provide multiple API-controlled models, including a zero-trust option where the encryption key never touches the server, providing a mathematical guarantee of privacy.
Key Difference 4: The Recording Philosophy - Perfect Fidelity vs. Complex Reconstruction
BigBlueButton records individual streams and attempts to reassemble them in post-processing, which can be a complex task.
Plug-N-Meet, as detailed in our Recording Philosophy, uses a headless browser to capture the final, rendered output. This produces a "what you see is what you get" MP4 file that is a perfect, high-fidelity replica of the live experience, ensuring all elements are perfectly synchronized.
Key Difference 5: Long-Term Maintainability and Upgrades
This is a significant consideration for any administrator.
BigBlueButton is tightly coupled to a specific OS version. The official upgrade path for a new OS often requires provisioning a brand new server and manually migrating all data and recordings. This can be a time-consuming and complex undertaking.
Plug-N-Meet completely avoids this problem by using Docker. The entire application runs in isolated containers, abstracting it from the host OS. You can upgrade your server's OS without breaking the application, and updating Plug-N-Meet is as simple as pulling a new Docker image. This makes long-term maintenance dramatically simpler and safer.
The Migration Path: Try Without the Risk
We understand that migrating from a deeply integrated platform is a big decision. That's why we made it painless.
Plug-N-Meet includes a BBB-compatible API layer. This means you can point your existing Greenlight, Moodle, or custom application to your Plug-N-Meet server, and it will work without any front-end code changes. This allows you to test the performance and stability of Plug-N-Meet in your own environment with zero risk.

Conclusion: The Right Tool for the Modern Web
BigBlueButton laid the foundation for open-source communication. It proved what was possible. As we detailed in our founder's story, "Why We Built Plug-N-Meet," our platform is the next step in that evolution, built from the ground up to meet the modern web's demands for elastic scalability, developer agility, and long-term maintainability.
If you are feeling the pain points of a monolithic architecture and are looking for a more flexible, performant, and cost-effective solution, Plug-N-Meet is the modern alternative you've been waiting for.
