MESHLINK HELP

From localhost to a secure link.

Learn how to install MeshLink, connect your account, share a local website, test APIs and webhooks, protect links with a password, and understand DIRECT, EDGE, and TURN connectivity.

TUTORIALS

What can you use MeshLink for?

WEB DEVELOPMENT

Preview a website on another device.

Run your React, Vite, Node, Django, Flask, or other local development server and open it from your phone or another PC.

MeshLink 3000
SHARING

Show a local project without deploying it.

Give a teammate or client temporary access to a development build while keeping the application on your computer.

MeshLink --target http://127.0.0.1:8080
API DEVELOPMENT

Test an API remotely.

If your API listens on localhost port 5000, MeshLink can expose that HTTP endpoint through the generated HTTPS URL.

MeshLink 5000
WEBHOOKS

Receive development webhooks.

Run your local webhook handler, start MeshLink on the same port, then use the generated HTTPS URL as the temporary webhook destination.

MeshLink 8080
DASHBOARDS

Open a local dashboard remotely.

Access a local development dashboard from another device without changing its localhost binding.

MeshLink --target http://127.0.0.1:9090
REAL TIME

Test WebSockets and SSE.

MeshLink supports normal web requests as well as WebSockets and Server-Sent Events through the secure bridge.

MeshLink 3000 --debug
ACCESS CONTROL

Password-protect a link.

For an additional access check before the proxied application is shown, start MeshLink with:

MeshLink 3000 --password

MeshLink asks you to enter and confirm the password locally.

Password: Confirm password:

Visitors must authenticate before reaching the local application. Do not send sensitive passwords together with the private MeshLink URL.

TEMPORARY LINKS

Choose a link lifetime.

Use --expires when you want the link to expire automatically. The value is in seconds and remains subject to your account plan limits.

MeshLink 3000 --expires 1800
180030 minutes
36001 hour
8640024 hours
CONNECTIVITY

DIRECT first. EDGE when needed. TURN last.

MeshLink prefers a DIRECT WebRTC path. If DIRECT cannot be established or its transport becomes unhealthy, MeshLink can switch to its encrypted EDGE path. If EDGE is unavailable, TURN remains the final WebRTC relay fallback.

DIRECT

Preferred path.

When peer-to-peer connectivity is healthy, debug output can show:

DIRECT WebRTC established. selected path: DIRECT.
EDGE

Encrypted reliability path.

If DIRECT is unavailable or its transport is unhealthy, debug output can show:

EDGE tunnel ready. selected path: EDGE.
TURN

Final relay fallback.

If DIRECT and EDGE cannot be used, debug output can show:

TURN relay WebRTC established. selected path: TURN relay.

EDGE carries MeshLink-encrypted transport data through MeshLatch edge infrastructure. TURN is contacted only as the final relay fallback when required. MeshLatch uses adaptive protection for sustained TURN traffic because TURN consumes relay infrastructure.

BROWSER COMPATIBILITY

Modern web applications work through the bridge.

HTTP / HTTPS Fetch XHR Forms Cookies SSE WebSocket LocalStorage SessionStorage IndexedDB Cache Storage Web Workers Canvas WebGL WebGPU

Browser permissions

Camera, microphone, geolocation, and screen capture are delegated so the browser can display its normal permission prompt. MeshLatch does not grant these permissions automatically.

Service Workers

Application-owned Service Worker registration is not supported in MeshLink v0.3.22. MeshLink uses its own Service Worker as part of the secure per-link virtual-origin bridge.

CLI REFERENCE

Commands.

MeshLink 3000

Share localhost port 3000.

MeshLink --target http://127.0.0.1:8080

Share an explicit loopback HTTP target.

MeshLink login ML-XXXXXXXX

Connect this device to your MeshLatch account using a single-use login code.

MeshLink account

Show the connected account and plan.

MeshLink logout

Remove the MeshLatch account credential from this device.

MeshLink 3000 --password

Password-protect the public MeshLink.

MeshLink 3000 --expires 3600

Request a one-hour lifetime, subject to your plan.

MeshLink 3000 --debug

Show detailed connection and diagnostic output.

MeshLink help

Show MeshLink's built-in help.

MeshLink --help

Show command-line options.

MeshLink --version

Show the installed MeshLink version.

TROUBLESHOOTING

If something does not connect.

Check the local application first.

Open your localhost URL directly on the host computer. MeshLink cannot expose an application that is not listening locally.

Use debug mode.

MeshLink 3000 --debug

Debug mode shows signaling, DIRECT/EDGE/TURN selection, WebRTC state, WebSocket activity, account heartbeats, and shutdown information.

Active link limit reached.

Stop an existing MeshLink with Ctrl+C. You can also manage your account or revoke active links from MeshLatch when necessary.

Not signed in.

Generate a new login code from your account and run:

MeshLink login ML-XXXXXXXX
SECURITY & PRIVACY

Designed for temporary localhost sharing.

Operational usage protection uses aggregate transport information such as byte counts, connection path, viewer counts, and timing. It is not designed to inspect the content of your local application.
