How Postman runs Agent Mode for 40 million developers on Amazon Bedrock
Postman runs AI Agent Mode for 40 million developers on Amazon Bedrock at production scale.
“Building an AI agent for a demo and operating one for 40 million developers are different engineering problems.”
Postman describes the architectural patterns behind its production AI Agent Mode, built on Amazon Bedrock, serving 40 million developers across API testing, documentation, and discovery. The key insight is that context management—not model quality or capability—proved to be the primary bottleneck when integrating an agent into a mature, interface-driven product. Patterns like controlling tool sprawl, schema-based reads, and multi-tier prompt caching offer reusable lessons for teams moving agents from prototype to production.
