Postman Agent Mode uses Anthropic Claude models through Amazon Bedrock to generate test suites and troubleshoot failing requests. This intelligence layer utilizes workspace context to diagnose issues. The platform holds the AWS AI Competency in Agentic AI Tools, a designation that validates support for the full development lifecycle across regulatory environments. The Amazon Bedrock architecture provides two inference profiles, In-Region and Geo Cross-Region, which help enterprises meet strict data residency and compliance requirements while using AI-powered developer tools in the field. PayPal uses this infrastructure to turn its commerce APIs into tools that agents discover and call. PayPal presented its MCP server as a Postman Collection at POST/CON 2025 to enable agent discovery. This collection uses Postman’s built-in OAuth support to reduce authentication friction. PayPal reported that its time to first API call dropped from 60 minutes to 1 minute after using these collections. Engineers on the Postman Enterprise plan save roughly one hour per week on API development workflows. The Postman AI Agent Builder also turns existing collections into production-ready MCP servers. This tool helps developers avoid a separate integration layer when building agents. Developers can use the Postman MCP server in Kiro to reach workspaces and environments from inside their IDE. The API Catalog aggregates specs, test execution data, and production observability into a single view.
Pricing, workflows, and performance
The March 2026 pricing restructure changed the landscape for small teams. Postman restricted its free plan to one user and 25 collection runs per month. This change drove many developers to search for alternatives like Bruno or Hoppscotch.
| Plan | Monthly Cost (Annual Billing) |
|---|---|
| Basic | $14 |
| Professional | $29 |
| Enterprise | $49 |
The platform now includes native Git workflows, which let developers work on feature branches and use pull requests to keep work synchronized with code. The API Catalog also provides a system of record by aggregating specs, test execution data, and production observability. Postman allows users to organize requests into collections and use JavaScript to write pre-request and test scripts. It also supports AES-256 encryption for sensitive environment variables. Users can generate mock APIs and auto-generated, real-time API documentation to speed up the development cycle. However, the application becomes sluggish when users manage large collections or work with multiple environments simultaneously. Users also report that collections fail to update across team members, necessitating manual re-imports. If you work in a tight-knit startup, you might find these per-seat costs difficult to absorb. Does the added value of the API Catalog justify the increased per-seat cost for small engineering teams?
Protocol variety and the Insomnia migration
Insomnia remains a strong contender for teams that prioritize protocol variety. It provides native support for REST, GraphQL, gRPC, WebSocket, SOAP, and Server-Sent Events. This makes it the most capable tool for testing modern microservices without requiring external plugins. Insomnia offers a free tier for up to three users with Git Sync. Many users fled to other tools after the Insomnia 8.0.0 update. This release made collections and plugins unavailable unless users created an account and logged in. This change created a significant problem for developers in regulated environments who work in closed systems without internet access. These users cannot store data on third-party servers or use software that forces cloud synchronization. Insomnia remains a lightweight option that uses less memory than Postman. It also allows users to send requests without an account via Scratch Pad mode. Insomnia provides environment variables and authentication wizards for dynamic requests. Insomnia’s Pro plan costs $12 per user per month. Kong maintains Insomnia under the Apache 2.0 license. Can a tool satisfy the needs of enterprise users if it removes the ability to work entirely offline?
