MuleSoft is an integration platform that connects SaaS & enterprise applications in the cloud and on-premise, but it's not typically defined as SaaS or PaaS. It's referred to as iPaaS (Integration Platform as a Service). MuleSoft has been recognized as an industry leader by multiple reporting industries, but it's often considered overpriced for small and mid-level organizations. The platform boasts an impressive customer list, including Airbnb, Netflix, Intuit, Verizon, and Airbus, and offers a range of APIs and integration tools. However, some reviewers have criticized the pricing model, with some feeling that it's starting to price out smaller customers. MuleSoft's competitors include RapidAPI, Boomi, Informatica, Apigee, LeadsBridge, Zapier, Workato, and Celigo, each offering alternative solutions for API management and data integration.
