API Architect vs Postman

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.

Postman is a platform for building, exercising, sharing, documenting, and monitoring APIs. Its API client handles multiple protocols and includes authentication, response inspection and visualization, variables, environments, and request history. For API design, it supports specifications, mock servers, importing definitions, multiple definition formats, and third-party integrations. Testing options include collection runs and automated, integration, performance, regression, and end-to-end testing, with Postman CLI also available. Listed integrations include Jira, Slack, GitHub, GitLab, Microsoft Teams, VS Code, Amazon API Gateway, AWS Secrets Manager, and 1Password Vault. Postman describes local secret protection, cloud detection, runtime resolution, and connections to secret-management services. Its stated compliance credentials include SOC 2 Type II, PCI DSS, HIPAA, GDPR, and others. It says customer data is not used to train its models and Enterprise teams control AI access and usage. The Free plan includes 50 AI credits. Solo is $9 a month, billed annually. Basic and Professional plans are closed to new customers; existing Professional customers retain their current plan and pricing.
