Build, test, and manage your entire API ecosystem with Postman's advanced tools and cloud-native collaboration. --- ## Why Postman? SoapUI was built for a desktop-first world centered on SOAP, but APIs have evolved. While SoapUI has added support for REST and GraphQL, many modern protocols and cloud collaboration features still require technical workarounds or paid upgrades. Sticking with SoapUI means dealing with Java dependencies, local installs, and outdated workflows. Along with powerful SOAP capabilities, Postman delivers seamless support for REST, GraphQL, gRPC, and WebSockets in a modern, cloud-native platform. Choosing Postman means faster delivery, easier scaling, and frictionless collaboration for the entire API lifecycle. --- #### Buy cheap, buy risk. Or buy once and unlock real business value at scale. --- ### Modern protocol support Can you test all your APIs (SOAP, REST, GraphQL, gRPC) in one place? **Postman:** Native support for SOAP, REST, GraphQL, gRPC, WebSockets, and more Import WSDL and generate collections Schema validation across all protocols Unified and visual workflow for mixed API architectures in one place **Soapui:** Primarily SOAP-focused with some REST support No native GraphQL or gRPC support Separate workflows for different protocols Limited schema validation beyond SOAP --- ### Performance & load testing Can you validate performance without complex setup and separate tools? **Postman:** Built-in performance testing through the Collection Runner & features that simulate parallel virtual users Visual, real-time metrics such as average response time, error rate, throughput, and customizable graphs Cloud-accessible reports and dashboards for monitoring and alerting CI/CD pipeline integration for automated testing **Soapui:** Load generation is primarily desktop-based Advanced load testing requires separate licensing (ReadyAPI Pro) Manual result interpretation and reporting No integrated reporting dashboards --- ### Developer experience Can your team adopt and scale testing practices quickly? **Postman:** Intuitive interface with minimal learning curve Extensive documentation and community support Pre-built templates, collections, and examples Automatic cloud-based updates & maintenance **Soapui:** Steep learning curve with complex interface Java dependencies and version management Limited community resources Manual updates and maintenance overhead --- ### Cloud-native collaboration Can your team work together seamlessly without software barriers? **Postman:** Web, desktop, and mobile access from anywhere Real-time collaboration with comments, versioning, and activity history in shared workspaces Instant sharing without installation requirements Cloud sync keeps everyone updated automatically across devices and platforms **Soapui:** Java desktop application only Manual sharing of projects through exports and imports No file sync or cloud workspaces Each team member needs local installation and setup No real-time collaboration features --- ### Integrated API lifecycle Do your tests, docs, and specs stay connected as APIs evolve? **Postman:** Connected workflow across design, testing, documentation, and monitoring Auto-generated documentation that updates with spec and collection changes Bidirectional sync between OpenAPI/Swagger specs and tests Editing a collection updates documentation, and vice versa Built-in mock servers, contract testing, and monitors support design-first iteration and continuous validation **Soapui:** Testing-focused with no lifecycle integration Manual documentation creation and updates No automatic connection between specs and tests Limited mocking capabilities Advanced mocking requires ReadyAPI upgrade --- ### Enterprise security Can you enforce standards and maintain compliance at scale? **Postman:** Encrypted Postman Local Vault for secrets management Sensitive data is always protected with industry-leading encryption Role-based access control (RBAC) with granular permissions, audit logs tracking user & team activity, and two-factor authentication (2FA) SOC 2 Type II & SOC 3, GDPR, HIPAA (offered through BAAs), PCI DSS, CCPA, and CSA STAR [compliance certifications](https://security.postman.com/) Configurable policy enforcement, security vulnerability scanning, and governance dashboards for visibility & risk management Bring Your Own Key (BYOK) encryption options **Soapui:** Local storage for credentials, which may expose security risks if mishandled No centralized governance or audit capabilities Provides security testing tools such as vulnerability scans, but does not offer enterprise-grade policy enforcement No official compliance certifications --- ### Modern protocol support **Challenge**: SoapUI was originally designed for SOAP services in an era with less diverse API protocols. Today's API landscape has evolved to include REST, GraphQL, gRPC, WebSockets, and hybrid architectures, which present challenges for teams relying on SoapUI. Users often face protocol switching difficulties, need multiple tools for full API coverage, and struggle to maintain consistent testing workflows across API types. **Why Postman**: Postman provides native and comprehensive support for modern protocols (REST, GraphQL, gRPC, WebSockets) while maintaining full SOAP compatibility. It allows teams to test all these protocols using consistent workflows, shared environments, and unified reporting. Postman's schema validation supports multiple protocols, reducing the need for protocol-specific expertise and helping ensure reliability. Postman enables: - Native SOAP/WSDL import with automatic collection generation - REST, GraphQL, gRPC, and WebSocket testing within the same workspace - Unified schema validation tools that work across protocols - Consistent authentication and environment management - Protocol-agnostic CI/CD integration with CLI tools - Cross-protocol contract testing and monitoring to maintain API quality **SoapUI considerations**: SoapUI is primarily focused on SOAP and offers strong WSDL support, but it only has basic capabilities for REST. It lacks native support for modern protocols like GraphQL and gRPC, which require external tools or integration workarounds. Multiple tools or plugins are required to effectively cover all API testing needs. Testing approaches can be inconsistent across protocols, leading to workflow disruption when switching between API types. Protocol switching often breaks workflow continuity, impacting team efficiency. ### Performance & load testing **Challenge**: SoapUI Pro provides advanced load testing features but requires a separate license, adding cost and complexity. Execution is primarily desktop-limited, hindering scalability for large load tests. Teams face challenges in setup time and complexity, interpreting results manually, and integrating performance tests into automated CI/CD pipelines. Functional and performance testing remain separate workflows, which introduces inefficiencies and disconnects. **Why Postman**: Postman integrates performance testing directly into the same workflows used for functional testing, enabling more seamless and efficient testing processes. Load generation occurs in a scalable cloud environment, automatically adjusting capacity as needed. Visual dashboards provide accessible and collaborative reporting for team members. Connecting with CI/CD pipelines via CLI ensures that performance checks happen all the time as part of the delivery process. Postman offers unified licensing that covers all testing capabilities, reducing the need for multiple tools or licenses. Postman enables: - Built-in performance testing with real-time, visual metrics and reporting - Cloud-based, scalable load generation that adjusts to demand automatically - Unified functional and performance testing flows within the same collections and environments - CI/CD pipeline integration for automatic performance validation in delivery cycles - Collaborative dashboards to analyze performance data across teams - Unified licensing that includes all API testing features without separate purchases **SoapUI considerations**: Advanced load testing requires Pro licensing, and load generation is desktop-restricted. Setup is complex, and result reporting is manual. There is no integration between functional and load testing workflows. ### Developer experience **Challenge**: SoapUI, built on a Java-based platform, presents adoption challenges due to a complex, less intuitive interface. New users face a steep learning curve compounded by having to manage Java dependencies, version compatibilities, and manual updates. Troubleshooting frequently requires dealing primarily with Java environment issues rather than focusing directly on API testing, adding operational overhead and slowing productivity. **Why Postman**: Postman focuses heavily on delivering a superior developer experience. It offers intuitive, user-friendly interfaces, minimizing the learning curve. Maintenance is largely automated through cloud-based, automatic updates that remove manual overhead. Postman also provides extensive documentation, video tutorials, pre-built templates, and a vibrant, active community that supports rapid onboarding and continuous learning. Multiple access methods, including web, desktop, and CLI, accommodate various user preferences and work styles. Postman enables: - Intuitive, modern interfaces designed for ease of use - Automatic maintenance and updates, reducing manual effort - Comprehensive documentation and learning resources - Pre-built templates to accelerate adoption and use - Large, active community providing knowledge sharing and support - Multiple access options: web app, desktop client, and CLI tools **SoapUI considerations**: There is a steeper learning curve due to SoapUI’s Java-based, feature-rich, but dated interface. Manual update processes and managing Java dependencies add complexity. Documentation resources are more limited and scattered compared to Postman. Configuration complexity and Java environment debugging extend onboarding time and create operational overhead. ### Cloud-native collaboration **Challenge**: SoapUI's desktop-first Java architecture inherently limits collaboration in modern distributed teams. Sharing tests requires manual export/import of project files. Collaboration relies on file transfers or external version control, leading to version conflicts, synchronization issues, and cumbersome remote work. **Why Postman**: Postman's cloud-native platform enables seamless, barrier-free collaboration for API teams. It supports instant sharing of collections and APIs via links without needing exports. Real-time collaboration with comments, activity history, and reviews keeps teams aligned. The platform provides consistent, secure access through web, desktop, and mobile clients with automatic cloud synchronization. Git integration is available without demanding command-line usage from all team members, and external partners can be involved easily. Postman enables: - Instant sharing through URLs - Real-time collaboration with commenting, versioning, and activity tracking - Access via web browser or desktop app - Automatic cloud sync updates everyone instantly - Git integration designed for ease of use without a command-line dependency - External collaboration with partners and stakeholders through Partner Workspaces **SoapUI considerations**: SoapUI is a Java desktop application that requires local installation per user. Sharing is limited to manual export/import of project files, while there is no integrated cloud sync or sharing. There are no built-in real-time collaboration features or commenting, so it needs external tools and manual coordination. Version conflicts are common when multiple users edit the same tests due to the lack of centralized control. Desktop-only access and file sharing complicate remote workflows. ### Integrated API lifecycle **Challenge**: SoapUI has traditionally specialized in API testing, creating gaps in other lifecycle stages such as design, documentation, mocking, and monitoring phases. Teams using SoapUI often rely on multiple, separate tools for API specifications, mock servers, documentation, and monitoring. This disconnected workflow leads to drift between API design and testing, duplication of effort, and integration problems at later stages. Manual updates across systems increase maintenance overhead and the risk of inconsistencies. SoapUI has traditionally specialized in API testing, leaving gaps in other lifecycle stages such as design, documentation, mocking, and monitoring. As a result, teams often depend on separate tools for specifications, mock servers, documentation, and monitoring. This fragmented approach creates drift between design and testing, duplicates effort, and introduces integration issues later on. Manual updates across disconnected systems add to the maintenance burden and increase the risk of inconsistencies. **Why Postman**: Postman offers a unified platform that seamlessly connects API design, testing, documentation, mocking, contract validation, and monitoring. When API specs change, Postman automatically updates test collections, maintaining bidirectional sync. Documentation is auto-generated and includes live interactive examples. Mock servers are integrated for early development and stakeholder validation. Contract testing verifies implementations match designs. Monitoring capabilities extend testing into live production environments. All activities occur within a single collaborative workspace, reducing tool switching and lifecycle friction. Postman enables: - Bi-directional sync between [OpenAPI](https://learning.postman.com/docs/design-apis/specifications/overview/) specs and test collections - Auto-generated documentation with live examples - Mock servers for early testing and stakeholder validation - Contract testing ensures implementation matches design - Monitoring extends testing into production - Single workspace for design, test, document, and monitor **SoapUI considerations**: SoapUI is focused on testing without integrated lifecycle management. Documentation creation and updates are manual and disconnected from tests. There is no automated connection between specs and test cases; synchronization relies on manual import/export. Mocking is available but more limited and less integrated, mostly requiring ReadyAPI Pro. It lacks native API monitoring or production visibility features. ### Enterprise security **Challenge**: SoapUI stores credentials locally with limited security controls. Teams have no visibility into who runs what tests, no audit trails for compliance, and no way to enforce consistent standards. As API portfolios grow, security risks and governance gaps become critical business concerns. **Why Postman**: Postman builds security and governance into every workflow. Secrets are encrypted and centrally managed, access is controlled through roles and permissions, and audit logs provide complete visibility. Compliance features like SOC 2 and GDPR alignment ensure enterprise readiness without sacrificing developer productivity. Postman enables: - Encrypted [Postman Local Vault](https://learning.postman.com/docs/sending-requests/postman-vault/postman-vault-secrets/) for secure credential management - [Role-based access control](https://learning.postman.com/docs/administration/roles-and-permissions/#team-roles) with detailed permission settings - Complete [audit logs](https://learning.postman.com/docs/administration/managing-your-team/audit-logs/) and activity tracking for compliance - [Compliance certifications](https://security.postman.com/), including [SOC 2](/security/compliance/), [GDPR](/security/compliance/), and [HIPAA](/security/compliance/) (offered through BAAs) - Policy enforcement and governance dashboards for enterprise oversight - [SSO](https://learning.postman.com/docs/administration/sso/intro-sso/) and enterprise-grade authentication mechanisms **SoapUI considerations**: SoapUI primarily stores credentials locally, which can increase security risk if devices are compromised. There is no centralized governance, role management, or access controls to regulate user actions. Audit trails are limited or nonexistent, complicating compliance efforts. It lacks formal enterprise compliance certifications. --- ## Postman is trusted by over 500,000 companies, 40 million users, and 98% of the Fortune 500 --- ## Industry recognition Don't just take our word for it—learn why G2 recognized Postman as the #1 API platform in 2024.
