LiveKit
Open-source realtime audio and video infrastructure for AI agents.
NOT REALLY
why this verdict
Keep it — OpenAI has not replaced it
OpenAI's version overlaps, but does not finish the voice & audio job, so this one is still worth keeping open.
- A named launch, not a vibe named, unlinked
- Nothing — the realtime voice boom runs on it. OpenAI, March 1, 2025 — no announcement link recorded yet.
- How much of the job it covers not the job editorial call
- Parts of it. The job still needs the tool to get finished.
- Is there a free way to do it? yes
- 2 of 2 listed replacements have a usable free tier: Daily and Agora.
- What the call is worth nothing to cancel
- No paid entry tier tracked, so there is no subscription to cancel.

The backstory
LiveKit is WebRTC infrastructure that became critical the moment voice agents needed to stream audio both ways with sub-second latency. It is underneath a striking share of the voice products people demo on X, including ChatGPT's own voice mode.
