Postman has for years been the go-to tool for API development and testing. However, new changes to Postman's pricing and features have prompted many teams and developers to look for alternatives. Luckily, there are now many outstanding options available that can match or even exceed Postman's features. In this article, we'll examine some of the best Postman alternatives for API testing, development, and collaboration.
Why Seek Postman Alternatives?
While Postman is still a widely-used and proficient tool, there are a few factors why developers may want to consider alternatives:
Fee modifications - Postman has moved to a per-user pricing model that can be pricey for larger teams
Mandatory cloud synchronization - Recent versions require syncing data to Postman's cloud, which some companies aren't happy about
Speed problems - As Postman has incorporated more features, some users mention slowdowns and crashes
Complication - The Postman interface has become quite complex as features have been incorporated
Restricted offline functionalities - Working offline with Postman has turned more difficult
Fortunately, there are now many superb Postman alternatives that address these problems while providing powerful API testing and development functionalities.
