Buy Pro

One-time purchase: JPY 1,980 (Japanese yen; about US$13 as of October 2026). No tax is added at checkout. Pay once. No subscription.

For desktop Chrome. Don't have it yet? Add to Chrome (free)

Payment is by card through Stripe. You are charged in Japanese yen (JPY 1,980 is about US$13; your card issuer sets the exact rate). We never see your card number. The payment page and your card statement may also show the name of another service run by the same operator (Many Lights).

How it works

Pay by card using the button above.
Your license key appears on the next page and is emailed to you. Keep it: you will need it again on a new computer.

Then activate Pro

Copy the license key first.
Click the CSS Glance icon in Chrome (it may be inside the puzzle-piece menu).
Hover any element on the page, then click “Copy CSS ★” in the panel.
Paste the key and click “Activate”. The badge changes to “Pro”.

Before you buy

Please try the free version first and check that it works on the sites you care about.
A license key is for the purchaser's own use. It may not be shared or transferred.
Because this is software, purchases cannot be refunded once the key has been issued. A refund, when due, is made by cancelling the charge on the card you used. If Pro does not work because of a fault on our side, contact us and we will fix it or refund you.
