API Architect vs Apigee API hub

API Architect is a web product for describing software architecture, business rules, APIs, and AI governance in a shared executable DSL. Its versioned language models systems, containers, and flows, while centralizing DTOs, compliance rules, and operational constraints. From those definitions, it generates APIs aligned with business needs, governance, and standards. Enterprise DSL is presented as a declarative language covering architecture, business, APIs, rules, AI, governance, and compliance. AI systems can load the DSL as an internal model so generated APIs follow business rules and governance boundaries. An example sets a market-specific maximum length for a resource field and defines a GET route returning that resource. Listed use cases include banking and insurance, retail and e-commerce, industry and energy, and SaaS publishers. Free costs nothing for one active project and community support; Starter is €29 a month; Pro is €79 a month.

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.
