Matter certificate badge for makers, bloggers and retailers
Paste a link or badge that sends readers to the CSA certificate for a Matter product. It is free, optional and needs no sign-up. 721 certified products have a page that states an exact CSA certificate, and each of those pages offers the code under “For publishers”.
The badge says only that a certificate is on the CSA ledger, with its ID. It is not the Matter logo and not an endorsement by MatterCatalog or the CSA.
As of October 28, 2026. Certificates from the CSA ledger read October 19, 2026. Updated October 28, 2026.

<script async src="https://mattercatalog.com/badges/matter-certificate-badge.v1.js"></script>What the badge says, and what it does not
It says that a CSA Matter certificate is on the Connectivity Standards Alliance’s ledger for the product, gives the certificate ID, and sends the reader to the product’s page here, where the certificate and its source are shown. That is all it claims.
- It is not the Matter logo. Only certified devices may show that, and we do not offer it.
- It is not an endorsement, rating or review by MatterCatalog or the CSA, and using it does not change how products are listed or ordered. We sell no badges or placement (Working with MatterCatalog).
- It does not say a product is sold in the US, works with an app, or is good. Certified and compatible are different claims (certified vs compatible).
The three versions
All three are an ordinary link to the product page, so the link is in your page’s HTML for readers and search engines. Pick the one that fits where you publish:
- Text link. One line of HTML; works in a blog post, a store description or a press page.
- Badge. A 220 by 48 pixel image (
/badges/matter-certificate-badge.v1.svg, under 1 KB) wrapped in the link. The image loads from our static files. - Styled badge (script). The same link plus one script tag (
/badges/matter-certificate-badge.v1.js, about 3 KB) that draws it as a badge and shows the certificate ID. It makes no request of its own, sets no cookie and tracks nothing. Without JavaScript, the plain link shows.
Both files are static and cached for a year under a versioned name: a new look would ship as version 2, and version 1 never changes under you.
Privacy, cost and removal
It is free, optional and needs no sign-up, account or contact with us. We do not ask for the badge to be placed anywhere and we never email people about it. To remove it, delete the link (and the script tag) from your page. Nothing else is installed.
The certificate data is the CSA ledger as read October 19, 2026, matched to each product by its certificate ID. If a certificate on a product page is wrong, write to team@mattercatalog.com with the product and the certificate ID. The MatterCatalog team
Brands can also use the free “Listed on MatterCatalog” badge, which links to the brand’s page and claims only a listing.
Questions people ask
What does the Matter certificate badge say?
Only that a CSA Matter certificate is on the ledger for that product, with its ID, and where to see it. The link goes to the product’s page on MatterCatalog, which states the certificate and its source. It is not an endorsement by MatterCatalog or the CSA, and it is not the Matter logo.
Does the badge cost anything or track my visitors?
No. It is free and needs no sign-up. The text link and the image version load nothing from us until a visitor clicks; the script version loads one small static file that only restyles the link. It sets no cookie and makes no other request.
Which products can have a badge?
Products whose MatterCatalog page answers “Is it Matter certified?” with Yes for the exact product: a CSA certificate that covers it, shown on an indexable page. That is 721 products today. A product family record, a claimed model or a bridged accessory gets none.
How do I remove the badge?
Delete the link (and the script tag, if you used the script version) from your page. Nothing else is installed and there is nothing to cancel.
Where does the certificate come from?
From the CSA’s Distributed Compliance Ledger, the official record of Matter certifications, read October 19, 2026, matched to the product by its certificate ID. The product page shows the ID and date; the CSA lookup shows the ledger record.
