Postman
The collaboration platform for API development. Simplify each step of building an API and streamline collaboration so you can create better APIs—faster. Postman is a collaboration platform for API development. Postman's features simplify each step of building an API and streamline collaboration so you can create better APIs—faster. Quickly and easily send REST, SOAP, and GraphQL requests directly within Postman. Automate manual tests and integrate them into your CI/CD pipeline to ensure that any code changes won't break the API in production. Communicate the expected behavior of an API by simulating endpoints and their responses without having to set up a backend server. Generate and publish beautiful, machine-readable documentation to make your API easier to consume. Stay up-to-date on the health of your API by checking performance and response times at scheduled intervals. Provide a shared context for building and consuming APIs, and collaborate in real-time.

Sourcey
Sourcey combines an open-source documentation engine with a public software research and data service. The documentation engine turns OpenAPI, MCP, Doxygen, Go, Rust, and Markdown sources into searchable static sites with customizable themes and self-hosted output. Developer teams can build locally or in CI and publish static HTML with search indexes, llms.txt, and API or MCP references. Sourcey's public service publishes source-backed startup offers and Agent Readiness report cards with dated evidence, unresolved conditions, and release history. Users can read records on the site or access them through JSON, a REST API, and MCP. The documentation engine is free under AGPL-3.0, and public research is free to read.

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.
