Postman has long been the favorite tool for API testing and development. However, recent changes to Postman's features and pricing have prompted many developers and teams to look for alternatives. Luckily, there are now many outstanding options on offer that can rival or surpass Postman's capabilities.

Forced cloud sync - Recent versions demand syncing data to Postman's cloud, which some organizations aren't happy about
Performance issues - As Postman has included more features, some users report slowdowns and crashes
Intricacy - The Postman interface has become quite complex as features have been included
Limited offline capabilities - Working offline with Postman has turned more difficult
