Apigee API hub vs Grapity

Apigee API hub centralizes API information so teams can discover, assess, organize, and manage an organization's API portfolio. Catalog entries can capture versions, specifications, operations, deployments, dependencies, and lifecycle details. Search supports filters and LLM-based free-text queries across API definitions. The hub parses OpenAPI specifications into definitions and operations and can provide linting feedback on imports. It can import proxy information from Apigee and Apigee hybrid projects, with synchronization scheduled every six hours. Other supported sources include Google Cloud API Gateway, Apigee Edge, and preview plugins for AWS API Gateway and Azure API Management; custom plugins can connect on-premises or multicloud sources. VPC Service Controls can constrain ingress and egress, and instance and search-data locations can be selected during provisioning. Advanced API Security is an additional add-on for risk assessment across multiple Apigee organizations, environments, and gateways, with some features excluded in multi-gateway use. The dashboard requires at least five registered APIs. Eligible Apigee organizations in supported regions can use it at no additional cost; pricing is also listed from $13, with a 60-day trial.

Grapity is an open-source API governance platform for teams coordinating API contracts and their consumers. Its Registry compares each pushed specification with the previous version and blocks breaking changes with an explanation. It enforces semantic version increments and tracks deprecation lifecycles, including consumers and sunset dates. The Hub offers a searchable API list, endpoint exploration, side-by-side version comparisons, and a version timeline. Grapity governs OpenAPI and AsyncAPI formats, with CI/CD integration and role-based access control. For Kong, Grapity Gateway generates configuration from registered specifications, and the CLI provisions it through decK; Kong can also send access logs to the Registry using its http-log plugin for queries and traffic statistics. The project says it is licensed under Apache 2.0 and has no features locked behind paywalls. Self-hosted use costs nothing, billed forever, with unlimited APIs and team members. Cloud costs $29.95 a month and includes five APIs and five users.
