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.
More
Tunnel sets
Save named configs with auto-connect, synced to your account.
History and API tokens
Connection history with traffic and API token management.
Open source
Server, CLI, desktop and web - all on GitHub. You can self-host too.
