Built for the loop you already run

Point a webhook at your laptop, open your dev server on a phone, or show a client work in progress.

Names that stay yours

Claim up to 10 subdomains per account. Register a webhook URL once and it keeps working across restarts, laptops and CI.

shop.tuzy.dev
stripe-hooks.tuzy.dev
client-preview.tuzy.dev

tuzy http 3000 --name shop

Inspect and replay

Every request lands in a local inspector. Replay it after a fix, or copy it as curl.

open http://127.0.0.1:4040

Dev servers just work

WebSockets, HMR and streaming pass through. If Vite rejects the tunnel host, tuzy switches the Host header for you.

tuzy http 5173

Many tunnels, one file

Describe your tunnels in tuzy.toml, start them together, or run them as a login service.

[tunnels.web]
addr = "3000"

[tunnels.api]
addr = "8080"

tuzy start --all

Free, with guardrails

tuzy is free for your own development traffic. To protect visitors from phishing, browsers see a short warning page on tunnels of accounts younger than 7 days. Webhooks, curl and API calls never do.
