WSO2 API Designer

Purpose: API Designer is a Visual Studio Code extension for building and improving OpenAPI specifications.
AI design: The extension includes an API Design Skill that works with GitHub Copilot to draft API specifications from prompts.
Visual editing: Design view displays API resources, operations, and reusable components and supports form-based editing of operations and schemas.
Specification format: API Designer supports creating and improving OpenAPI 3.x specifications and opens YAML or JSON specification files.
Governance: It checks specifications with bundled Spectral rulesets for WSO2 AI readiness, WSO2 REST API design guidelines, and OWASP API Security Top 10.
AI readiness: AI-assisted analysis combines rule-based results with narrative feedback about specification issues that can affect agents and tools.
Custom rules: Users can point the extension to a custom ruleset folder using a GitHub folder URL or an absolute local directory path.
Integration: GitHub Copilot is optional and recommended for AI-assisted workflows; the extension can be installed from the VS Code Marketplace.
Requirement: The documented VS Code prerequisite is compatibility with extension engine requirement ^1.100.0.
Support: The documentation directs users to WSO2’s official Discord community for help and discussion.
Security note: WSO2’s API Designer guidance warns that security findings may require real URLs, policies, or authorization server metadata and advises against inventing production values with AI.
Maker security: WSO2 states that it is ISO 27001:2022 certified and SOC 2 Type 2 compliant.
Intended users: WSO2 describes its 30-day trial as ideal for students and individual developers, and its Growth plan as intended for small to mid-sized businesses with basic API management needs.
