Autostub
AutoStub® is an essential tool to speed up API development. It can significantly reduce your build time by quickly designing, prototyping, documenting and testing APIs. AutoStub® creates a functional mock that allows developers to work with APIs before they are fully implemented.
Available as a SaaS offering, for On-Premise deployments and in a hybrid model.
Key Features

ATA
ATA is an AI-powered API management platform that centralizes design, testing, governance, documentation, and lifecycle workflows into a single intelligent workspace to help teams design, build, test, maintain, and govern APIs with higher quality and collaboration. It keeps API code, design documentation, specifications, test cases, and release notes in sync, reducing manual effort and drift while supporting OpenAPI specs, mock servers for frontend progress without backend readiness, and scheduled API monitoring to detect slow responses, timeouts, or failures early. It includes a Developer Studio for design-first OpenAPI creation and version control, E2E Test Automation with AI-generated robustness and security tests, mock servers, chained API workflows, and UI automation testing, and a Documentation Portal that centralizes API docs with multi-editor support, version management, secure access control, and auto-linked live endpoints.

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.
