How many websites use OpenCms?

We track 1,166 websites that use OpenCms in 2026. Those sites span 40 industries and 30 countries. The crawler re-checks each domain daily. So the count moves as sites adopt OpenCms or drop it.

OpenCms belongs to the CMS 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 OpenCms most?

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

Higher Education14.000000000000002%
Government Administration13%
Banking7.000000000000001%
Information Services7.000000000000001%
Research Services5%

Higher Education leads that list. However, the long tail matters just as much. Adoption reaches 40 industries in total. So you can narrow the list to the segment you sell into.

Where are websites that use OpenCms based?

The matched companies sit in 30 countries. These lead the sample:

Spain 30
Germany 17
Italy 8
Switzerland 5
Brazil 4

Spain 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 OpenCms

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

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.
