Apidog vs WSO2 API Designer

Apidog is an API platform for designing, debugging, mocking, testing, and documenting APIs, with GraphQL and SOAP support. Its specification-led workflow can generate request parameters, body content, and mock data, then check responses against specifications. For automated testing, users can arrange request sequences, add assertions, extract variables, and save requests as endpoint cases. It imports Postman data and supports Postman scripts. Database operations include MySQL, SQL Server, PostgreSQL, and Oracle on Free; ClickHouse, MongoDB, and Redis are listed for paid tiers. The CLI can connect to Jenkins, GitHub, and GitLab, and activity notifications can go to Slack or webhook-compatible tools. Deployment choices include Global and Europe SaaS services and an on-premises option hosted on customer servers. Apidog says desktop requests travel directly from the user's computer to the target server, not through Apidog servers. The free plan is time-unlimited for four users; paid plans start at $9/user/mo (annual), with a 14-day trial.

WSO2 API Designer is a Visual Studio Code extension for creating and refining OpenAPI 3.x specifications in YAML or JSON. Its design view presents API resources, operations, and reusable components, with form-based editing for operations and schemas. An API Design Skill can draft specifications from prompts with GitHub Copilot; Copilot is optional. The extension checks specifications against bundled Spectral rulesets for WSO2 AI readiness, WSO2 REST API design guidelines, and the OWASP API Security Top 10. AI-assisted analysis adds narrative feedback to rule-based findings, including issues that may affect agents and tools. Users can also point it to custom rules in a GitHub folder or an absolute local directory. Installation is available through the VS Code Marketplace, with documented compatibility for extension engine requirement ^1.100.0. WSO2 directs users to its official Discord community for discussion and help. API Designer is available in a free 30-Day Trial with limits of 5 Managed Interfaces and 10M Gateway Events. Growth costs $119 a month. Enterprise pricing is custom and not listed. WSO2 warns that security checks may need real URLs, policies, or authorization-server metadata; AI should not invent production values.
