How many websites use Classnames?

We track 254 websites that use Classnames in 2026. Those sites span 38 industries and 21 countries. The crawler re-checks each domain daily. So the count moves as sites adopt Classnames or drop it.

Classnames belongs to the JavaScript libraries category. Sites in that category tend to share a similar stack. As a result, they often share buying patterns too.

The table above shows a sample of 100 matched companies. Each row carries an industry, a country, and a live domain. You can search it, sort it, and export it.

Which industries use Classnames most?

Adoption is not spread evenly. Instead, a few industries account for most of the matched sample:

Higher Education28.999999999999996%
Information Technology and Services8%
travel arrangements4%
Research Services4%
Information Services4%

Higher Education leads that list. However, the long tail matters just as much. Adoption reaches 38 industries in total. So you can narrow the list to the segment you sell into.

Where are websites that use Classnames based?

The matched companies sit in 21 countries. These lead the sample:

Türkiye 33
United States 24
United Kingdom 7
Russia 5
Australia 4

Türkiye is the largest single market in this sample. Because the country is stored per row, you can filter before you export. That keeps your outreach inside one timezone and one legal regime.

How to find websites that use Classnames

Start with the table above. Then follow these four steps to turn it into an outreach list:

Filter the sample. Narrow by industry or country until the rows match your ideal customer profile.
Export the domains. Share the page to unlock the CSV, or sign in for the full dataset.
Find the people. Run each domain through Domain Search to pull every work email behind it.
Verify before you send. Pass the results through the Email Verifier so your bounce rate stays low.

Working at volume? Push the whole export through Bulk Tasks instead, or call the Domain Search API directly from your own stack.
