As a language model, I do not have the ability to browse the internet or provide information that is up-to-date beyond my cutoff date of 2023. However, I can provide you with a list of 10 of the best free responsive WordPress themes that were popular at the time of my knowledge cutoff, in no particular order:

  1. Astra
  2. Hestia
  3. OceanWP
  4. Neve
  5. GeneratePress
  6. Ashe
  7. Zillah
  8. Writee
  9. Phlox
  10. Shapely

Keep in mind that there may be newer and better free responsive WordPress themes available beyond 2023, so it’s always a good idea to do your own research and read reviews before choosing a theme for your website.
