Redocly vs WSO2 API Designer

Redocly is an API documentation and governance suite for teams creating, maintaining, and monitoring API experiences. Redoc generates reference documentation from OpenAPI definitions, with automatic code samples, mock servers, and interactive testing through Replay. Reunite supports collaborative editing, visual reviews, remote content, and deployment previews with an audit trail; it connects to GitHub, GitLab, Azure DevOps, or Redocly’s native Git solution. The open-source CLI validates, lints, and bundles OpenAPI definitions, while the VS Code extension helps write and maintain them and flags definition errors. Reef provides a searchable internal API catalog with metadata, scorecards, and discovery features. Respect monitors APIs against an OpenAPI specification and can send alerts through Slack or email. Redocly lists web, API, and extension platforms, custom domains, and content analytics. It says data is encrypted in transit and at rest and reports a completed SOC 2 Type II audit. Pro costs $10.00 per seat/month, billed monthly, and includes one project and 100 pages. API docs can be launched for free, and the full suite has a 30-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.
