tunnel.pizza hands out tunnels, and tunneld, the command that asks for them, is a thin layer over other people’s work. Thank you to:

• libtunnel, the tunnel engine inside tunneld, behind every mint and every connection to Cloudflare’s edge.
• cloudflared, Cloudflare’s tunnel protocol and edge client, which libtunnel links in.
• cri-streaming, Kubernetes’ streaming library, which every terminal tunneld serves is attached through.
• coder/websocket and gorilla/websocket, the WebSockets underneath it all.
• Charm: Bubble Tea, Ultraviolet, x/ansi, x/vt and colorprofile, which the whole terminal frame is built on, on a console and in a tab.
• xterm.js, the terminal in a browser tab.

The full list, everything tunneld depends on directly, is in tunneld’s README, where a test keeps it in step with what tunneld actually requires. The license notices for everything a tunneld binary links ship as THIRD_PARTY_LICENSES with each release.
