One report card

An overall grade plus Performance, Security and SEO scores — the same holistic view as the web app.

Three scans, ten runs

Cold + warm browser runs from a Zurich edge node, with security surface and on-page SEO in the same pass.

Background scanning

Close the popup, switch tabs, keep working. The scan keeps running and notifies you the moment it's done.

One click, any tab

The URL auto-fills from the page you're on. Hit Race and read the report without losing your place.

Install in under a minute

Not on the Chrome Web Store yet — installs via Chrome's built-in "Load unpacked" flow.

1
Download & unzip
Grab laptime-extension.zip and unzip it. You'll get a folder named laptime-extension.
2
Open the extensions page
Go to chrome://extensions in your address bar (works in Chrome, Edge, Brave and Arc).
3
Enable Developer mode
Flip the Developer mode toggle in the top-right corner.
4
Load unpacked
Click Load unpacked and select the unzipped laptime-extension folder.
5
Pin it
Click the puzzle-piece icon in your toolbar and pin Laptime so it's one click away.
Keep the unzipped folder somewhere permanent — Chrome loads the extension directly from it. Deleting or moving the folder removes the extension.

How to use it

From any page you want to measure.

1
Open the popup
Click the Laptime icon. The URL of your current tab is pre-filled automatically.
2
Hit Race
A 10-run scan kicks off — five cold, five warm — alongside the security surface and on-page SEO audit.
3
Walk away
Close the popup or switch tabs. The scan finishes in the background and a notification lets you know it's ready.
4
Read the report card
Reopen the popup for the overall grade, then tab through Performance, Security and SEO — or open the full report on laptime.dev.
