What is the primary advantage of using cloud-based API testing tools in terms of scalability and collaboration?

The primary advantage of using cloud-based API testing tools for scalability and collaboration is on-demand resource allocation. Cloud platforms provide the flexibility to scale resources based on testing needs, ensuring optimal performance during peak periods. This scalability facilitates efficient collaboration among distributed teams, allowing them to access testing environments and resources as needed. While offline testing capabilities, in-house data security, and local execution speed are important considerations, they are not the primary advantages related to scalability and collaboration.
