Postman vs Stoplight

Postman logo infront of Spotlight logo. Illustration.

Why Postman?

Unlike Stoplight's design-focused solution that creates workflow gaps at critical stages of the API lifecycle, Postman's purpose-built solution streamlines the entire API lifecycle in one workspace, enables development velocity and team collaboration, and balances developer-friendly interfaces with enterprise-grade governance, making it the trusted choice for both developers and enterprises.

See how it stacks up against Stoplight's capabilities for API design, documentation, and more.

Challenge: Organizations are struggling with fragmented API development processes that lack cohesive integration across the entire lifecycle, from API design to build and management.

Why Postman: Postman unifies API design, testing, documentation, and monitoring into one seamless platform, eliminating tool sprawl and misalignment.

With Postman, you get:

  • Full lifecycle capability coverage, from design and mocking to testing and observability
  • Everything in a single, unified workspace
  • Seamless one-click transitions between lifecycle stages
  • Support for multiple formats & protocols like OpenAPI, Async, GraphQL, gRPC, SOAP, RAML and REST

Stoplight Considerations: Stoplight offers a fragmented approach to API development with significant gaps in crucial areas. While Stoplight handles basic API design, teams quickly hit roadblocks when trying to build complete, modern API programs that demand comprehensive protocol support, robust testing, and ongoing monitoring.

Postman is trusted by over 500,000 companies, 35 million developers, and 98% of the Fortune 500

Why teams choose Postman

These are the most common questions we hear from teams evaluating Postman as a modern API platform:

Is Postman more than just an API testing tool?

Yes. Postman supports the entire API lifecycle — including design, mocking, testing, documentation, publishing, monitoring, and governance — all in one platform.

Postman is unified. Postman is a complete API platform. It supports every stage of the API lifecycle — from design to testing, documentation, collaboration, and monitoring. Stoplight focuses primarily on API design and documentation, with limited lifecycle support and no integrated testing or monitoring.

Yes. Postman includes powerful design tools (OpenAPI, Async, GraphQL, gRPC, RAML, SOAP) and extends collaboration across the full lifecycle with workspaces, commenting, tagging, and governance — all in one place.

Absolutely. Postman combines a developer-loved experience with the security, scale, and governance needed by enterprises — including SSO, RBAC, audit logs, BYOK, and advanced admin controls.

Real results. On average, customers report 52% faster release cycles, 77% higher quality APIs, and 46% lower total cost of ownership by moving away from SmartBear products like Stoplight, consolidating tools and automating workflows on Postman.

Debunking common myths

Stoplight may make some claims about Postman — here are the facts:

Is Postman used for design & documentation?

Absolutely. Many teams are designing their API specifications starting in Postman and then having it flow through the rest of the lifecycle in one fluid workflow. As a matter of fact, Postman enables you to design your specification upstream in the design phase or have it retroactively created from your collection downstream. No other solution enables you to design your specifications with this type of flexibility.

No. Stoplight focuses on the design and documentation phases, with limited support for testing, mocking, or monitoring. Postman, in contrast, supports the full lifecycle — reducing friction, tool switching, and communication breakdowns.

Yes. Postman supports OpenAPI, Async, GraphQL, gRPC, RAML, WebSockets and SOAP/WSDL — far beyond Stoplight's OAS/JSON Schema limitation.

Stoplight may be simple to start with for individual developers and very small teams, but it lacks the flexibility and scalability growing teams need. Postman is equally intuitive for individuals but provides advanced features for organizations as they scale.

What evaluation teams want to know

Evaluators often ask about security, extensibility, automation, and integration — Postman delivers.

Can I test APIs directly inside Postman?

Yes. Postman includes automated testing, scripting, environment variables, test chaining, and integrations into any CI/CD pipeline — all natively. Capabilities that Stoplight doesn't have.

Yes. Teams can collaborate on collections, tests, and docs in real time, with inline comments, tagging, version control, and workspace sharing — even across organizations. With Stoplight, collaboration doesn't go beyond the design & documentation phase.

Yes. Postman offers native monitoring that checks your APIs on schedule, alerts on failures, and integrates with your observability stack (e.g., Datadog, Splunk).

Yes. Postman supports OpenAPI imports and allows you to move your design work into a more complete platform without losing progress. You'll gain testing, collaboration, and monitoring features in one environment. Many customers have migrated over successfully.

Postman integrates security into the development lifecycle — including API security scanning, governance enforcement, and audit-ready logging. It enables secure collaboration without compromising developer speed, helping you detect issues earlier and reduce risk exposure. In addition, Postman itself prioritizes your company's data protection through encryption, product and application security, and organizational measures.

Yes. Postman supports fine-grained RBAC, workspace permissions, and team-level governance policies. You can enforce standards for access, testing, documentation, and deployment — while maintaining oversight and control across all environments.

Absolutely. Postman offers enterprise-level auditing, data residency options, and compliance-friendly features such as BYOK, security logging, and version tracking — making it easier to meet regulatory and internal compliance requirements.
