Cosmo OSS is a powerful way to start with GraphQL Federation, providing speed, flexibility, and open-source capabilities. As teams grow and systems become more complex, managing everything in-house can become harder due to operational overhead, limited visibility, and compliance requirements. Cosmo Enterprise builds on the same core and adds governance, observability, and support needed to scale with confidence without starting over. It's ideal for early adoption, internal evaluations, or rolling out Federation in lower environments before considering the full platform. While open-source OSS is not free and requires collaboration rather than consumption, it can be an excellent choice for small projects or initial evaluations. However, as teams grow and requirements become more complex, migrating to Cosmo Enterprise may be necessary due to increased operational burden, limited visibility, compliance pressure, and performance issues. The platform provides governance, observability, support, and scalability features to help teams move forward safely with incremental, non-disruptive migrations.
