Company's website information

You can use website filters to find companies that are using a certain technology or companies that are active in social media.

Technology filter is one of the most commonly used filters in Vainu. You can find different technologies through the following three filter categories:

1) Technology 

  • Vainu scans automatically technologies from website source code. Vainu also receives technology information from other public sources. You can find technologies by category in the filters or by selecting the All filter and typing in a search.
  • You can see a short description of each technology on company cards, which helps you understand what that technology tells about the company.
  • You can find website technologies under the Technology section in the filters.
