What is API Design Software for Linux?

API design software helps developers design, document, and manage APIs (Application Programming Interfaces) in a structured and efficient manner. These tools provide a user-friendly interface for creating API specifications, defining endpoints, input/output data formats, authentication methods, and response formats. API design software typically supports the OpenAPI (formerly Swagger) specification or other industry-standard formats to ensure consistency and interoperability. Additionally, many API design tools allow for collaborative development, testing, and version control, making it easier to create robust, secure, and scalable APIs that are aligned with best practices.
