OpenCV leads on 1 check, Google Cloud Vision API on 0, and 5 are even. Who comes out ahead on the 6 yes/no, price and count checks where we have data for both products. The editor score weighs everything else too.

Our verdict

  • Highest scoreOpenCV · 9.3/10
  • Free planboth
  • Most featuresOpenCV · 5 of 5

OpenCV scores higher on our rubric for ai image recognition software: 9.3 against 9.2 out of 10; our editors rank them #1 and #2.

OpenCV offers face recognition; Google Cloud Vision API doesn't. On deployment options, OpenCV gives you Edge where Google Cloud Vision API offers Cloud.

OpenCV is the better fit for free, broad, cross-platform computer vision. Google Cloud Vision API is the better fit for managed cloud recognition APIs.

  • OpenCV fits best

    Free, broad, cross-platform computer vision

  • Google Cloud Vision API fits best
