2. What is WebRTC?
2.1 Definition of WebRTC
WebRTC (Web Real-Time Communication) is an open web standard that enables real-time audio, video, and data communication directly between browsers and devices. It is built into modern browsers and does not require plugins, extensions, or additional software.
Developed and standardized by the World Wide Web Consortium (W3C) and the Internet Engineering Task Force (IETF), WebRTC provides a set of APIs that allow browsers to communicate with each other in real time using secure, peer-to-peer connections.
In simple terms, WebRTC allows voice, video, and data communication to work natively inside web pages and applications, making real-time interaction a core capability of the modern web.
With broad support across major browsers and operating systems, WebRTC has become a foundational technology for browser-based communication and interactive web experiences.
2.2 Where is WebRTC used?
WebRTC is widely adopted across many real-world applications, including:
- Video conferencing applications (browser-based meetings and calls)
- Customer support live chat systems with audio or video features
- Online collaboration tools for teams and remote work
- Real-time web applications that require instant data exchange
Because WebRTC enables direct, low-latency communication between users, it is especially well suited for applications that rely on real-time interaction rather than delayed, server-based messaging.

3. How does WebRTC work?
WebRTC enables real-time communication by establishing a direct connection between devices and allowing them to exchange audio, video, and data efficiently. All of this happens at the browser level, without requiring plugins or external software, making the process seamless for both users and developers.
At a simplified level, a WebRTC connection follows this flow:
User’s device → STUN/TURN services → Peer-to-peer communication channel → Recipient’s device
3.1 Establishing a peer-to-peer connection
When a WebRTC-based audio or video call begins, the application first needs to connect all participating devices. Instead of sending media through a central server, WebRTC is designed to create a peer-to-peer (P2P) communication channel whenever possible.
Modern networks often involve firewalls and different network configurations. To handle this complexity, WebRTC automatically determines how devices can reach each other and selects the most efficient connection method available. This process is handled transparently in the background, without user interaction.
By using a peer-to-peer approach, WebRTC minimizes latency and delivers a smoother real-time communication experience.
3.2 Connection setup and real-time data exchange
Once the connection parameters are established, WebRTC opens a private communication channel between the participating devices. Through this channel, browsers can:
- Transmit audio and video streams in real time
- Exchange data for messaging, file transfer, or synchronization
- Maintain responsive, low-latency communication
WebRTC relies on built-in browser APIs to access hardware such as microphones and cameras, capture media streams, and deliver them securely to the connected peers. Because only the devices involved in the session are aware of the connection details, communication remains isolated within the call.
3.3 The role of STUN and TURN (High-level overview)
To support connection establishment across different network environments, WebRTC uses auxiliary services such as STUN and TURN servers.
- STUN servers assist browsers in determining how they can communicate with other devices.
- TURN servers provide a relay mechanism when a direct peer-to-peer connection is not feasible.
These services help WebRTC navigate complex network conditions and ensure that real-time communication can be established reliably, without exposing users or developers to low-level networking details.
4. Why WebRTC is important for modern websites

6. WebRTC as part of browser behavior and fingerprinting
WebRTC is not only a communication technology, it is also part of how modern browsers handle connections and interact with the network environment.
From a technical standpoint, WebRTC reflects:
- How a browser establishes real-time connections
- How it interacts with underlying network conditions
- How certain browser capabilities are exposed during communication setup
Because of this, WebRTC is often considered a technical component of the browser environment, alongside other browser behaviors that influence how web applications function and interact.
For specific professional groups such as developers, digital marketers, and technical operators, understanding and managing browser behavior is an important part of building, testing, and scaling web-based systems. In these contexts, WebRTC is viewed as one of several browser-level technologies that may require awareness and control, depending on the use case.
At this level, WebRTC should be understood as a functional browser mechanism, not inherently good or bad, but relevant within the broader context of modern web architecture and browser behavior management.
7. How to manage WebRTC with Hidemyacc
WebRTC is enabled by default in most modern browsers and plays an important role in real-time communication. For everyday users, this default behavior is usually sufficient. However, in more advanced use cases, managing how WebRTC behaves at the browser level can become necessary.
7.1 Why manage WebRTC instead of using default browser settings?
Modern browsers are designed to provide a one-size-fits-all experience. While this works well for general users, it offers limited flexibility for professional or large-scale workflows.
In practice:
- Each browser profile may require different behavior and configurations
- Default browser settings do not allow granular control over how WebRTC interacts with the browser environment
- Managing multiple profiles using the same default behavior can create inconsistencies during testing or operations
For these reasons, WebRTC management is often considered part of browser environment control, rather than a standalone feature.
7.2 How Hidemyacc helps change WebRTC
Hidemyacc approaches WebRTC management at the browser profile level, rather than modifying the browser globally.
With Hidemyacc:
- WebRTC is handled individually within each browser profile
- WebRTC behavior is aligned with other profile components, including:
- Proxy configuration
- Browser fingerprint settings
- The browser’s natural behavior is preserved, ensuring compatibility with real-world web applications
- This profile-based approach allows users to manage WebRTC consistently without breaking core browser functionality.
7.3 When should WebRTC be adjusted?
Adjusting WebRTC behavior is typically relevant in scenarios such as:
- Managing multiple browser profiles simultaneously
- Running testing or automation environments
- Operating structured multi-account workflows that require isolated browser environments
In these cases, WebRTC management becomes part of a broader strategy for maintaining consistency and control across browser profiles.

8. Best practices when working with WebRTC
WebRTC is a core browser technology designed to support real-time communication. When working with WebRTC in professional environments, a balanced and informed approach helps maintain stability, compatibility, and long-term reliability.
8.1. Avoid over-modifying WebRTC behavior
WebRTC is deeply integrated into modern browsers. Making extreme or unnecessary changes can lead to unexpected behavior, compatibility issues, or broken real-time features.
Best practice is to:
- Adjust WebRTC only when there is a clear technical reason
- Avoid disabling or heavily altering it without understanding the broader impact on browser behavior
8.2. Be cautious with third-party extensions
Not all browser extensions handle WebRTC in a reliable or transparent way.
When using extensions:
- Avoid tools from unclear or unverified sources
- Be aware that extensions may interfere with native browser behavior
- Consider long-term stability and maintainability rather than quick fixes
Uncontrolled extensions can introduce inconsistencies that are difficult to diagnose later.
8.3. Keep WebRTC consistent with the browser environment
WebRTC works best when it aligns naturally with the overall browser setup.
This means:
- Keeping WebRTC behavior consistent with the browser profile
- Ensuring it matches related elements such as network configuration and browser capabilities
- Avoiding isolated changes that conflict with the rest of the environment
Consistency helps reduce unexpected results across sessions and profiles.
8.4. Prefer integrated solutions over fragmented adjustments
Managing WebRTC in isolation often creates more complexity.
Whenever possible:
- Use integrated, profile-based solutions
- Manage WebRTC as part of a broader browser environment strategy
- Avoid stacking multiple tools that modify similar browser components independently
An integrated approach leads to cleaner workflows and more predictable outcomes.
