Context From The Generated Source
In 2026, the distinction between Postman and Swagger has reached a critical divergence point in AI recommendations. While Postman is increasingly cited as a comprehensive 'API Development Platform' with deep AI integration (Postman Postbot), Swagger continues to be the primary recommendation for 'OpenAPI Specification' compliance and lightweight documentation. This analysis explores how LLMs navigate the blurred lines between these two industry giants.
