Cloud Tunnel

Share your mocks with the world. One command.

Expose your local mock server through a public HTTPS URL. Works with every protocol Mockd supports. No signup required for anonymous tunnels.

tunnel
$ mockd tunnel --port 4280
Tunnel connected!
HTTP: https://a1b2c3d4.tunnel.mockd.io http://localhost:4280
Auth: none (tunnel URL is public)

How It Works

Three steps. No configuration files, no accounts, no hassle.

1

Start your mock server

Run mockd start to launch your local mock server on any port.

2

Run one command

Execute mockd tunnel --port 4280 to create a public tunnel.

3

Share the URL

Send the public HTTPS URL to teammates, clients, or webhook providers. They connect instantly.

Multi-Protocol

All Protocols, One Tunnel

Every protocol Mockd supports works through the tunnel. HTTP, gRPC, WebSocket, MQTT, and more — all over a single HTTPS connection.

Built for Developers

Tunnels designed around how developers actually work. Fast, secure, and zero friction.

Zero Config

No signup required for anonymous tunnels. Just run the command and share the URL.

All Protocols

HTTP, gRPC, WebSocket, MQTT, SSE, GraphQL, and SOAP — all through a single tunnel.

Fast & Reliable

Encrypted connection with 0-RTT reconnect after network changes. Works through firewalls and NAT.

Tunnel Auth

Protect with token, Basic Auth, or IP allowlists. Control who can reach your mocks.

Single Port

Everything through port 443 — works behind corporate firewalls and restrictive networks.

Instant URLs

Get a public HTTPS URL in under 2 seconds. No waiting, no provisioning, no delays.

Multi-Protocol Examples

Tunnel any protocol with the same command. Here are a few real-world examples.

gRPC Tunnel

MQTT Tunnel

MQTT tunnel
$ mockd tunnel --port 4280 --mqtt 1883
Tunnel connected!
MQTT: a1b2c3d4.tunnel.mockd.io:443

Use Cases

Tunnels unlock workflows that are impossible with local-only mock servers.

Webhook Development

Receive webhooks from Stripe, GitHub, Shopify, or any provider directly on your local machine. No need to deploy a staging server.

Team Sharing

Share your mock server with teammates working remotely. Everyone uses the same tunnel URL to test against your mocks.

Client Demos

Demo an API to a client without deploying anything. Spin up a tunnel, share the URL, and walk them through the endpoints live.

CI/CD Integration

Use tunnels in CI pipelines to expose mock servers for integration tests that need a public endpoint, like OAuth callbacks.
