Microsoft Computer Vision - Provides image analysis and description. The free tier offers 5,000 transactions per month.

Google Cloud Vision API - Google's image recognition service. The free tier offers 1,000 requests per month.

OpenCV - A popular computer vision and machine learning software library. Can be used to build custom image recognition models and applications.

Tensorflow/Keras - Deep learning frameworks that can be used with transfer learning to build image classifiers. Free to use and open source.

IBM Watson Visual Recognition - IBM's visual recognition service. The free tier offers 50 API calls per month.

Alteryx Computer Vision - A library of computer vision tools for tasks like object detection, image classification etc. Open source.

DeepDetect - A framework for deep learning microservices including image recognition. Free for non-commercial use.
