MOQtail

MOQtail is a Draft 18-compliant MoQ Transport toolkit that provides type-safe APIs in both TypeScript and Rust for building publishers, subscribers, and relays. Developed by a team at Özyeğin University under Professor Ali C. Begen, the project includes reference implementations and demo applications using the LOC and CMSF formats.

Key features

• Type-safe TypeScript and Rust APIs
• Publisher, subscriber, and relay components
• WebTransport integration
• Deployable relay service (local and containerized via GHCR)
• Demo applications for real-time, live, and on-demand streaming
• LOC and CMSF format support

Components

• Relay — Deployable MoQT relay service
• Publisher SDK — Build MoQ publishers
• Subscriber SDK — Build MoQ subscribers
• Player — Web-based demo player at player.moqtail.dev

Public relay endpoints

MOQtail operates the largest fleet of any implementation in this directory — ten published endpoints on moqtail.dev, listed below with what each answered the last time the moqtap TestLab sweep measured them. The project owner states MOQtail is not a production relay, so none of it should be read as a service level.

They are not one relay behind ten names. The n1 nodes are named by airport code and answer from Singapore, Chicago, Frankfurt and Osaka; the demo endpoints — WatchParty, SyncPlay, TimeTravel and IBC2025 — sit on their own ports and answer on different drafts from each other, as far apart as draft-11 and draft-18. Six of them identify themselves in their setup response as moqtail/0.14.1 — the main relay and the four n1 nodes at build +74eb97c, WatchParty at +fbdbc75. Version and commit is the credible form of self-identification, and it is what makes two of these endpoints distinguishable at all.
