Stoplight

Leading API design-first platform within the broader API lifecycle management space

Stoplight is a collaborative API design and documentation platform that enables development teams to design, document, mock, and govern APIs throughout their lifecycle. The company provides tools that allow teams to work with OpenAPI and JSON Schema specifications through visual editors, automated documentation generation, and design governance features. Stoplight's platform emphasizes a design-first approach to API development, enabling both technical and non-technical stakeholders to participate in API design processes. The platform serves software development teams, API product managers, and technical writers who need to create consistent, well-documented APIs. Stoplight's tools include visual API designers, automated documentation generators, mock servers, and style guides for API governance. In 2021, Stoplight was acquired by SmartBear Software, a provider of software development and quality tools, and continues to operate as a distinct product within SmartBear's portfolio. While Stoplight is not an AdTech company, it operates in the API tooling and developer tools space, serving organizations across various industries including technology companies that may build advertising technology solutions. The platform focuses on improving API development workflows and ensuring API quality and consistency across organizations.
