How many websites use C3.js?

We track 144,404 websites that use C3.js in 2026. Those sites span 58 industries and 25 countries. The crawler re-checks each domain daily. So the count moves as sites adopt C3.js or drop it.

C3.js 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 C3.js most?

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

Information Technology and Services7.000000000000001%
Law Practice6%
Information Services4%
Automotive3%
Education Management3%

Information Technology and Services leads that list. However, the long tail matters just as much. Adoption reaches 58 industries in total. So you can narrow the list to the segment you sell into.

Where are websites that use C3.js based?

The matched companies sit in 25 countries. These lead the sample:

United States 43
Brazil 10
United Kingdom 9
Germany 5
Australia 4

United States 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 C3.js

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.

Frequently asked questions

How many websites use C3.js?

We track 144,404 websites that use C3.js. The index refreshes daily, so the number shifts as sites adopt or drop it. Of those, 100 are matched to a company profile with industry, location, and contact data.

Can I download the list of websites that use C3.js?

Yes. Share the page on LinkedIn to unlock a CSV export of the matched sample, with no signup required. For the full dataset and verified email addresses, create a free Tomba account.

Which industries use C3.js the most?

Information Technology and Services leads the matched sample, at 7.000000000000001% of companies. In total, websites that use C3.js span 58 industries.

How fresh is the C3.js data?

Our crawler re-checks technology signals daily. So a site that removes C3.js drops out of the index, and a new adopter appears without you refreshing anything.

Can I get email addresses for websites that use C3.js?

Yes. Every domain in the table can be enriched with verified work emails and direct phone numbers. Run a single domain through Domain Search, or push the whole export through Bulk Tasks.
