Defining the Standard for AI-ready APIs
Swagger sets the standard for API design, testing, and governance in the age of AI. It automates and centralizes visibility, governance, and discoverability, while AI-assisted building, testing, and documentation help teams deliver faster, operate predictably, and scale with confidence.

Build
Build and govern APIs built for humans and agents. Leverage AI-assisted API generation, MCP server creation, automatic linting against internal style guides to redefine what AI-ready APIs can mean for you. Swagger is essential for teams to collaborate on governed APIs built for both humans and agents without sacrificing quality.
Enhance team collaboration
- API Design for Everyone: Empower cross-functional teams with a visual, code-optional editor, making it easier for non-technical users to contribute to API design from the start.
- One API Catalog, One Source Of Truth: Organize and manage all your API descriptions in a centralized catalog that promotes consistency, reuse, and discoverability across teams.
- Faster Feedback Loops: Accelerate reviews with in-line commenting on API descriptions, streamlining team input and enabling quicker iteration.
Ensure high-quality, consistent APIs
- Enforce Standards With Ease: Apply pre-built templates and style guides to drive consistency, reusability, and faster API delivery.
- Work Across Multiple Specifications: Support both OpenAPI and AsyncAPI to accommodate a wide range of API styles and architectural patterns.
- Build Once, Reuse Everywhere: Standardize core components like data models, parameters, and headers to reduce duplication and accelerate development.
Simplify your workflow
- Seamless Integrations: Connect with version control systems, CI/CD pipelines, and API gateways.
- Flexible Export Options: Export designs in multiple formats to meet development needs.
- Automated Mock APIs: Generate mock servers instantly to test endpoints without manual setup.
Portal
Automate your API documentation for humans and agents alike. Swagger Portal allows you to generate comprehensive and rich API documentation and on-boarding guides using traditional methods or MCP tools to ensure your APIs are discoverable and consumable.
Productize APIs for accelerated consumption
- Control API Visibility: Decide whether to expose your APIs publicly or restrict them to authorized users—ensuring the right level of access for every use case.
- Centralize And Simplify Documentation: Consolidate all your API assets in a single, searchable portal for better discoverability, version control, and lifecycle management.
- Improve Developer Experience: Provide intuitive guides and actionable resources to simplify onboarding and accelerate integration.
Enhance discoverability
- Branded API Portal: Customize the portal to reflect your brand, providing a cohesive experience.
- Centralized API Catalog: Organize and showcase all your APIs in one accessible location.
- Search and Filter: Allow users to easily find APIs and endpoints relevant to their needs.
Streamline API documentation and access control
- Assign Roles And Permissions: Tailor access and editing rights across your team to simplify documentation workflows and maintain governance.
- Flexible Rendering Options: Choose between multiple documentation formats—like Swagger UI or markdown-style rendering—to suit both internal and external audiences.
- Unified API Documentation: Consolidate all your API specs and related content in one portal to improve discoverability, reduce context switching, and keep consumers aligned.
“API Hub for Portal is promising to be a game changer for our onboarding process and developer experience. The use of the product concept to describe different parts of our system, combined with seamless integration with other API Hub products, means that developers have a one stop shop to get all the latest API information alongside visually appealing up to date documentation.”
—Senior Tech & Developer Experience Lead, Webio
“With the entire suite of SmartBear tools in play, we are improving release quality and receiving positive customer feedback.”
—Head of Delivery, Triquestra
“We can easily standardize the API design and achieve the level of quality we expect, more efficiently and more easily.”
—Industry Standards Manager, IATA
“Adding API Hub for Contract Testing to our test automation strategy gives the team the confidence to move forward when they see validation between the provider and consumer."”
—Head of Test Engineering, M1 Finance
Contract Testing
Move fast. Don't break customer expectations. Validate APIs while they're still in development. Swagger’s AI-enabled Contract Testing empowers teams to discover consumer insights and detect integration issues early. Generate, review and maintain contract tests automatically and receive AI-driven suggestions for improvements.
Deploy with confidence
- Proactive Validation: Catch breaking changes early by validating API contracts throughout development, reducing production risks.
- Bulletproof Pipelines: Orchestrate complex CI and CD pipelines and use can-i-deploy to tell you when a component is safe to release.
- Protocol Versatility: Validate APIs across HTTP, Kafka, and more, ensuring broad compatibility and real-world readiness.
Say goodbye to painful release processes
- Scalable Workflows: The bi-directional contract testing workflow makes it simple for new teams to get started.
- Reduced Complexity: Remove the need for complex, costly and hard-to-manage integration test environments.
- AI-Driven Reliability: Use HaloAI to automate test generation and maintenance, keeping tests in sync with evolving APIs and enabling more reliable deployments.
Accelerate release cycles
- AI-Enhanced Efficiency: Detect testing gaps, optimize workflows, and accelerate time-to-market with minimal manual effort and HaloAI-driven accuracy.
- Proactive Issue Detection: Understand the impact of any change at the point of design or code modification, enabling faster resolution and smoother releases.
- Remove Testing Bottlenecks: Contract tests can be written during development - no need to wait for the other side of your integration to be ready.
