Watch QUIC beat TCP: animated handshake RTT race, 0-RTT resumption, multiplexing without head-of-line blocking, connection migration. Free.
HTTP/3 & QUIC Visualizer
Animated handshake race, 0-RTT, multiplexing, migration
Press play and watch three handshakes race. QUIC folds the TLS handshake into the transport, so the first round trip is the only round trip.
TCP + TLS 1.3
Classic HTTPS
QUIC
HTTP/3, first visit
QUIC 0-RTT
Repeat visit, resumption
Why it matters: every round trip costs 50-200ms of latency. On a repeat visit QUIC sends application data in the very first packet, while TCP is still saying hello.

About this tool
IconVault's HTTP/3 and QUIC Visualizer makes the internet's newest transport protocol visible. Press play on the handshake race and watch TCP+TLS take two round trips while QUIC finishes in one, and 0-RTT sends data in the very first packet. Then see multiplexing survive packet loss that freezes HTTP/2, and watch a connection migration keep streaming while TCP dies on a Wi-Fi to cellular handoff.
Every scene is animated step by step with plain-English narration, and you can export a key-takeaways note for study or slides. Everything is free and runs fully in your browser: no signup, no server, just the protocol brought to life.
