Video SDK

👋 Hey Product Hunt, I’m Arjun, co-founder of VideoSDK.

I'm beyond excited to launch our Open-Source AI Voice Agent SDK.

Today, voice is becoming the new UI. We expect agents to understand us, respond instantly, and work seamlessly across web, mobile, and even telephony. But, to achieve this, developers have to stitch together: STT, LLM, TTS, glued with HTTP endpoints and, a prayer.

This most often results in agents that sound robotic, hallucinations and fail in product environments without observability.

So we built something to solve that: End-to-End infrastructure to build, deploy, and monitor your AI Voice Agents

Here’s what it offers:

• Global WebRTC infra with <80ms latency

• Native turn detection, VAD, and noise suppression

• Modular pipelines for STT, LLM, TTS, avatars, and real-time model switching

• Built-in RAG + memory for grounding and hallucination resistance

• SDKs for web, mobile, Unity, IoT, and telephony — no glue code needed

• Agent Cloud to scale infinitely with one-click deployments — or self-host with full control

Think of it like moving from a walkie-talkie to a modern cell towers that handles thousands of calls.

VideoSDK gives you the infrastructure to build voice agents that actually work in the real world, at scale.

I'd love your thoughts and questions! Happy to dive deep into architecture, use cases, or crazy edge cases you've been struggling with.

🔥 This is a game-changer for anyone building with voice! Love how you're simplifying the entire stack for real-time Voice AI—especially the flexibility across telephony, web, mobile, and even robotics. Open-sourcing it makes it even more powerful for indie hackers and startups. Huge kudos to the team 👏

this looks promising, makes your main product a full stack video & audio framework for building agents.

Congrats on the launch team!
