How many websites use Offline.js?

We track 6,093 websites that use Offline.js in 2026. Those sites span 33 industries and 16 countries. The crawler re-checks each domain daily. So the count moves as sites adopt Offline.js or drop it.

Offline.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 Offline.js most?

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

Information Technology and Services7.000000000000001%
Higher Education6%
Information Services4%
Operations Consulting3%
Software Development2%

Information Technology and Services leads that list. However, the long tail matters just as much. Adoption reaches 33 industries in total. So you can narrow the list to the segment you sell into.

Where are websites that use Offline.js based?

The matched companies sit in 16 countries. These lead the sample:

Japan 50
United States 17
United Kingdom 4
Canada 2
Australia 2

Japan 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 Offline.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.
