API gateway software gives you a set of options to compare for handling API access and requests. Look at authentication methods, supported protocols, rate limiting, and request transformation across the entries. Deployment model and free-plan availability can also help distinguish the choices, while monthly request limits and paid-from pricing provide further cost and capacity details. Kong Gateway, Apache APISIX, and Tyk Gateway are among the first entries, followed by KrakenD API Gateway. The 22 products are ranked; use that order together with the stated comparison fields to identify which capabilities and deployment considerations matter for your APIs.
