Everything fxTunnel does

More than a tunnel. Protocols, domains, inspector, security and a desktop app in one place.

Protocols

HTTP, TCP and UDP

One command: fxtun http 3000, fxtun tcp 22, fxtun udp 25565. HTTP and TCP on every plan, UDP on paid plans.

WebSocket out of the box

Bidirectional WebSocket passes through transparently, nothing to configure.

Domains

Any subdomain right away

Pick myapp.fxtun.ru when you start a tunnel, no random URLs. Skip it and we generate a readable name.

Subdomains forever

Reserve a subdomain for yourself - it stays yours, even when the tunnel is offline.

Custom domains with HTTPS

Connect mydomain.com via a CNAME or A record. A Let's Encrypt certificate is issued automatically, ownership is confirmed with a TXT record.

Traffic inspector

See every request

Method, path, headers, body, status and timing - in the web and in the desktop app.

Replay and edit requests

Replay a request in one click or edit it before sending - handy for catching webhooks.

Desktop app

GUI for Windows, macOS and Linux

The only tunnel with a full desktop app. Mouse control, tray operation, auto-reconnect.

Client and launch

One command

fxtun http 3000 - and you're online. Cross-platform CLI.

Several tunnels at once

Describe tunnels in YAML and run them as a daemon: fxtun up, status, down.

Token in the system keyring

Log in with fxtun login, the token is stored in the OS keyring. The client self-updates.

Security

End-to-end TLS

Traffic is encrypted all the way.

Basic Auth per tunnel

Lock a tunnel with a login and password: fxtun http 3000 --auth user:pass.

IP filtering

Allow only the subnets you need: --allow-ip. Plus auto-close on idle and a lifetime limit.

Token scopes

Restrict a token by subdomains, IP and number of tunnels.

Sign-in

Yandex, Google, GitHub, email

Sign in via OAuth or a magic link to your inbox. Two-factor (TOTP) is available.
