Audience
Engineering teams building microservices and APIs who need to reduce integration bugs, accelerate parallel development, and ensure API compatibility.
About Specmatic
Specmatic offers a no-code, specification-driven, visual approach to API testing by leveraging API specifications to automatically execute positive and negative tests. Specmatic Studio offers broad format and protocol support across REST, SOAP, GraphQL, gRPC, WebSockets, and asynchronous messaging systems (message queues and event-driven APIs).
The platform provides a comprehensive toolkit for API development and testing, utilizing specs as the single source of truth.
Key features include:
• Contract testing across various protocols
• Service virtualization and mocking
• Workflow and resiliency testing
• Backward compatibility checks to prevent breaking changes
• Open-source testing tools for OpenAPI, MCP and SOAP
• Postman collection import for spec creation
Specmatic focuses on functional correctness, contract compliance, resiliency, and compatibility testing.
Genie assists API design, enabling interactive validation of the API spec prior to generating an MCP server.

Routebase
Routebase is the single source of truth for your APIs. Design your OpenAPI spec once in a visual editor — no hand-edited YAML — and your documentation portal, mock servers, contract tests, and monitoring all derive from that one spec.
Change the contract, publish, and Routebase catches what drifted before your consumers do: it validates live responses against the spec and flags every divergence with field-level diffs — missing fields, type mismatches, undocumented additions.
Work on specs the way you work on code: branch, review, merge, with breaking-change detection before anything ships. Publish a docs portal on your own custom domain. Spin up realistic mocks so frontend and backend build in parallel. Run contract and security tests against any environment.
Every workspace also ships a built-in MCP server, so your AI agents read and act on the same source of truth, under your team's permissions — no glue code.

API Agent
API Agent in IBM API Connect is a watsonx.ai–powered assistant that automates core tasks across the entire API lifecycle via a natural‑language, conversational interface. Built on an agentic framework, it lets teams rapidly generate OpenAPI specifications, mocked responses, and rich documentation for design‑first projects, or connect to backend data sources, build application code, and auto‑deploy to Code Engine for code‑first workflows, all without manual setup. To combat API sprawl, API Agent intelligently searches your existing API catalog by simple description prompts, recommending reusable endpoints and reducing duplication. It enforces governance by validating specs against organizational rulesets, suggesting or applying fixes automatically, and boosts quality with a built‑in testing suite that generates and runs semantic test cases to catch issues early.

create-api.dev
Create-API.dev is an AI-powered OpenAPI specification builder by Kong that lets you generate high-quality API specs in seconds through a simple chat interface. By messaging the service, you provide your desired endpoints or rough outline, and an underlying Google LLM crafts complete, standards-compliant OpenAPI definitions that are ready to share, test, and ship. As a lightweight, web-based tool, it requires no installation. The generated specs can be exported in standard YAML or JSON formats for seamless integration with your existing API gateways and documentation pipelines. Create-API.dev operates under Google’s Generative AI Prohibited Use Policy and advises discretion before relying on or publishing any AI-generated content.
