When WebRTC was first introduced by Google over a decade ago, it came with the promise of simplicity. “Just drop in a little JavaScript and you’ve got video chat in the browser with no downloads necessary!” While that vision helped kickstart a wave of innovation in real-time communication, the reality has always been more complex. Especially when building real-time communication apps at scale. At WebRTC.ventures, we regularly hear from teams who have working demos that

WebRTC is a foundational technology behind many real-time communication applications, including telehealth platforms handling sensitive health data and enterprise collaboration tools exchanging confidential business information. While WebRTC offers strong security by design, building a secure application requires more than just relying on its built-in protocols. This WebRTC Security 2025 guide explores WebRTC’s core security mechanisms, such as DTLS and SRTP, alongside the most common implementation risks and best practices. Whether you're developing a browser-based video

Voice AI applications are changing how businesses handle customer interactions and how users navigate digital interfaces. These systems process spoken requests, understand natural language, and respond with generated audio in real time. Building a voice AI application requires understanding speech processing, language models, and real-time communication infrastructure. You need systems that can detect when users finish speaking, convert audio to text, generate appropriate responses, and convert those responses back to audio. This guide covers the

AI-powered voice agents are transforming communications across industries like telecom, healthcare, and enterprise customer service. But delivering low-latency, natural-sounding AI responses in real time at low costs remains a major challenge. Leveraging the “lightweight AI” of Small Language Models (SLMs) and free open-source stacks can help overcome the latency and cost barriers of real-time voice AI. At ClueCon 2025, taking place in Chicago from August 4–7, WebRTC.ventures CTO Alberto Gonzalez will give a talk entitled,

WebRTC applications present unique operational challenges that traditional monitoring tools cannot address. Unlike conventional web applications, real-time communication systems operate with complex peer-to-peer connections, dynamic network conditions, and media processing pipelines that can fail silently or degrade gradually. The primary challenge lies in observability. WebRTC applications generate extensive telemetry data for example, ICE candidate exchanges, DTLS handshakes, media statistics, and network quality metrics, but this data remains largely inaccessible to development teams. When users report

In a previous post, Reducing Voice Agent Latency with Parallel SLMs and LLMs, we showed how to reduce response times and create more natural conversational experiences using the LiveKit Agents framework. But optimization is only half the equation. Once your voice agents are deployed and handling real conversations, you need comprehensive monitoring to measure latency, track costs, and ensure optimal performance. Voice AI agents present unique observability challenges. Real-time audio processing, variable LLM latency, and

Voice assistants powered by real-time AI are increasingly being used to automate phone-based customer interactions. Whether for contact centers, internal help desks, or voice-driven workflows, a reliable architecture needs to support low-latency audio streaming, accurate speech-to-text (STT), intelligent response generation, and real-time speech synthesis. In this post, we walk through how to build a serverless Voice AI assistant that runs entirely on the scalable power of the AWS infrastructure, using Twilio ConversationRelay as the telephony

Bringing WebRTC and SIP together is a powerful way to connect modern web applications with traditional phone systems. Whether you’re enabling voice and video in the browser, or linking your app to a PBX and SIP trunk, WebRTC SIP integration allows users to communicate across platforms without needing special hardware or downloads. While the goal is clear, the integration process can be complex. WebRTC and SIP use different signaling protocols, media formats, and security models.

Large Language Models (LLMs) have dominated conversations about AI integration in WebRTC, particularly when it comes to voice-based features like transcription, summarization, and intent detection. But there’s an emerging layer that many outside of research circles are missing: Vision Language Models (VLMs). Unlike LLMs, which work with text and speech, VLMs are capable of understanding and generating language based on visual inputs—opening up new possibilities for analyzing what’s happening on camera during a WebRTC session.

Real-time video communication applications face unique scalability challenges that can make or break the user experience. When thousands of users simultaneously join virtual classrooms,  video conferences or other streaming video experiences, traditional autoscaling approaches often fall short. The key to managing predictable traffic spikes in WebRTC applications lies in proactive scaling strategies that anticipate demand before it hits your infrastructure. Scheduling scaling ensures your infrastructure is ready ahead of demand, avoiding the latency issues that
