In a world where every second counts, delivering real-time video content is no longer a luxury — it’s a necessity. Whether you’re powering an online classroom, launching a telehealth app, or hosting a live event, WebRTC (Web Real-Time Communication) is one of the most powerful tools for ultra-low latency streaming.
If you’re new to WebRTC or want a deeper technical dive, check out our complete guide on how WebRTC works.
In this blog post, we’ll break down the top benefits of using WebRTC for streaming, why it’s a preferred choice over traditional protocols like RTMP and HLS, and how platforms like
Ant Media Server make real-time broadcasting easier and more scalable than ever.

What is WebRTC?
WebRTC is an open-source project that enables audio, video, and data transmission directly between browsers and mobile apps—in real time. It’s supported by all modern browsers and does not require any third-party plugins or software.
Unlike legacy streaming protocols, WebRTC is built for speed, interaction, and security, which makes it ideal for the next generation of live streaming use cases.
Key Benefits of WebRTC for Streaming
1. Ultra-Low Latency (Sub-500ms)
Latency is one of the most crucial factors in live streaming. Delays of even a few seconds can disrupt interactivity, cause viewer frustration, and degrade the overall user experience. WebRTC offers latency as low as 200 to 500 milliseconds, which is significantly faster than other protocols.
Traditional streaming technologies like HLS introduce delays ranging from 10 to 20 seconds. Even RTMP lags behind with delays of 2 to 5 seconds. In contrast, WebRTC’s real-time performance enables use cases that demand instant feedback and interaction.
Use Case: A telemedicine provider uses Ant Media Server’s WebRTC capabilities to facilitate real-time doctor-patient consultations. The low latency ensures smooth communication, immediate feedback, and a better experience for both parties.

2. No Plugins – Works Directly in the Browser
WebRTC is supported natively in modern browsers like Chrome, Firefox, Safari, and Microsoft Edge. This eliminates the need for users to download or install additional software, significantly lowering barriers to entry.
In today’s mobile-first world, reducing friction is key to increasing engagement and conversion rates. WebRTC provides a seamless, plugin-free experience that enhances accessibility and broadens your reach.
That means your users can join a stream instantly, which improves retention and conversion rates—especially on mobile.
3. Built-in Security and Encryption
WebRTC includes secure communication features by default. It uses Datagram Transport Layer Security (DTLS) and Secure Real-time Transport Protocol (SRTP) to encrypt both data and media streams.
This built-in security ensures that sensitive information, such as medical data or financial transactions, is protected during transmission. It also helps your application stay compliant with data protection regulations like GDPR, HIPAA, and PCI-DSS.
Use Case: A fintech startup relies on Ant Media Server to deliver secure, real-time KYC (Know Your Customer) video calls. The platform’s WebRTC support ensures that data privacy and compliance requirements are met.
4. Adaptive Bitrate for Better Viewing Experience
One of the common challenges in streaming is network inconsistency. Users on slower or unstable connections often experience buffering or quality degradation.
WebRTC solves this with adaptive bitrate streaming. It dynamically adjusts the video quality based on the viewer’s network conditions, ensuring a smooth experience across all devices and locations.
Ant Media Server enhances this feature by offering server-side adaptive bitrate support, making it easier to deliver high-quality video to viewers without overburdening their connections.
5. Scalable with SFU Support
WebRTC started as a peer-to-peer protocol, which works great for one-on-one communications. However, when you need to stream to multiple users simultaneously, a more scalable approach is required.
Enter SFU—Selective Forwarding Unit. An SFU receives media streams from multiple participants and forwards them to others without decoding and re-encoding. This significantly reduces server load and bandwidth requirements.
Use Case: An education platform uses Ant Media Server’s SFU mode to conduct virtual classrooms with over 10,000 concurrent students. The platform maintains real-time interaction with minimal server strain.

6. Cross-Platform Streaming (Mobile, Desktop, Embedded)
WebRTC is inherently cross-platform. It works on desktop browsers, mobile browsers, and native applications. For developers, Ant Media Server offers SDKs for Android, iOS, and JavaScript, making it easy to integrate WebRTC functionality across multiple platforms.
Whether you’re building a consumer-facing mobile app, a B2B dashboard, or an embedded IoT solution, WebRTC allows for consistent, high-quality video experiences everywhere.
Use Case: A leading platform delivering content directly to mobile lock screens redefined live streaming using Ant Media Server SDKs. Read the story.
