Does the investor need to install anything?

No. They get a URL. They click it. They see your local build. Nothing to install, no account to create.

What if my local server crashes mid-demo?

The popup logs each failed request with its reason. Restart your server and the same link serves the app again while the session is live.

How is this different from ngrok?

ngrok gives you a tunnel. wiremaven runs from a Chrome extension and adds a live session log in the popup: viewer connections, request outcomes, errors, and time left, visible to you during the walkthrough.

Can I use wiremaven for a group investor call?

Yes. Multiple reviewers can share the same link at once. You see each viewer connection in the popup.

Is the local port public?

No. Your machine connects outbound to the wiremaven relay. Reviewers access the relay URL; no inbound port is opened on your machine.

How it works

Three steps in under thirty seconds.

If your app is running on localhost, you can create a shareable link in 30 seconds and keep live session signals in view.

Start a session

Open the wiremaven extension, enter your app's port, pick an expiry, and click Start.

wiremaven popup

▶port 3000 · session 30M · Start

✓ connected

✓ link: relay.wm/p/investor-demo

✓ expires: 30M · session log: on

Share the link

Copy the relay URL from the popup and drop it into Slack, email, or a calendar invite.

Watch the session

The popup shows viewer joins, request outcomes, and errors as they happen.

wiremaven

viewer_connected: Investor opened link

request_completed: Pricing page loaded

request_completed: Checkout flow clicked

tunnel_expired: Window closed at 30m

Why wiremaven

Stop guessing what happened during the demo.

The call ends and you may not know which flows they clicked, whether anything broke, or if they were paying attention. wiremaven gives you the session record.

Real work

Show the build, not a slide.

Advisors and investors want to click through the actual product. wiremaven shares the live local build.

Visibility

Know who reviewed it.

See when the investor opened the link, which flows they clicked through, which requests failed, and when they left. You can skip the follow-up email.

Control

Keep the window scoped.

Set an expiry before you share. The link closes when the window ends.

Speed

No deployment required.

If it's running on localhost, you can share it in under 30 seconds.

The shift

Before: guessing. After: a full session record.

Before

Zoom share drops 10 minutes in
No idea which flows they clicked
Silent errors you can't see on your screen
There is no staging URL yet
Tunnel left open long after the call ended

After

Reviewer clicks your link without Zoom or install
Viewer connections and request feed visible in real time
Errors surface with request context
Share localhost with no staging
Link expires when the session ends

What you get

Everything the review needs, without extra setup.

time-boxed

Expiry you control

Set the link lifetime to 15, 30, or 60 minutes. Click Stop to close it sooner.

visibility

Viewer connections

See when each reviewer opened the link. Skip the 'are you there?' check.

signals

Request outcome feed

Every request the reviewer triggers is visible: successes, failures, and timing.

no install

No reviewer account

Reviewers click the link and land on your local build. No signup, no install.

encrypted

Encrypted tunnel

Traffic flows over an encrypted relay. Your local server never opens a public port.

controlled

Closes on expiry

When the window closes, access closes with it.
