Postman provides an API development platform that helps developers, teams, and organizations design, test, document, and monitor APIs. Its tools cover the full API lifecycle: creating API schemas, sending and automating requests, validating responses, generating documentation, and watching API performance in real time. Work happens in shared workspaces so teams can collaborate on API collections, environments, and tests. Pricing is subscription-based with a free tier to attract individuals and convert them to paid plans, plus premium features and enterprise solutions for larger organizations. Compared to others, Postman combines design, testing, documentation, and monitoring in one platform with strong collaboration and a broad user base, making it easier for teams to manage APIs across different projects. The company’s goal is to simplify building and using APIs, enabling real-time data exchange and scalable API development for organizations of all sizes.

Postman integrates Anthropic's Claude to bring AI-native API development to 40M developers

Postman, the API platform used by over 40 million developers, has integrated Anthropic's Claude model to power its Agent Mode feature. The AI assistant runs on Amazon Bedrock, providing enterprise-grade security and compliance controls. Agent Mode operates within developers' Postman workspaces, using Claude's reasoning capabilities to generate API collections, debug requests, maintain documentation and keep code synchronised. Developers can also access Postman workspaces directly from Anthropic's tools, including Claude Code and Claude.ai. The integration allows developers to search workspaces, generate client code, run API tests and create mock servers without switching tools. Postman, which serves 500,000 organisations including 98% of Fortune 500 companies, reports that users engaging with Agent Mode show consistently higher usage rates.

Dynatrace and Postman integrate AI-powered observability into API workflows with Agent Mode

Dynatrace has expanded its partnership with Postman to integrate AI-powered observability into Postman's Agent Mode, enabling developers to access real-time production data directly within their API workflows. The Dynatrace Model Context Protocol Server is now available in the Postman API Network. The integration allows developers to connect Agent Mode with Dynatrace observability data, surfacing trusted telemetry and correlating API behaviour with live production information. Teams can test APIs, analyse failures and resolve issues using natural language within a single workflow, reducing friction between development and operations. Postman Agent Mode is an AI agent that helps teams build, test and manage APIs using context from existing collections, code and governance standards. The Dynatrace MCP Server is now available via the Postman API Network.
