OhAPI
macOS / developpeurs
OhAPI is a native macOS app for developers and API architects who work with OpenAPI specifications. It makes complex definitions easier to understand through an interactive tree visualization, a powerful code viewer, and a dedicated operations browser.
Interactive Tree Visualization
Turn your specification into a clear, structured graph: schemas, properties, parameters, references, and compositions (allOf, anyOf, oneOf) become visual nodes with color cues.
•Expand/collapse sections to stay focused
•Select a node to automatically highlight the corresponding source
•Jump through $ref references instantly
•Smooth animations for easier reading
JSON/YAML Viewer with Syntax Highlighting
Read the raw spec with a view optimized for clarity:
•JSON and YAML syntax highlighting
•Line numbers
•Two-way sync between “tree ↔ source” (auto-scroll to the relevant line)
Operations Browser
Browse your API by endpoints and HTTP methods:
•Operations list (GET, POST, PUT, DELETE, etc.)
•Details (summary, operationId, description)
•Requests and responses grouped by HTTP status (2xx, 4xx/5xx, default)
Reference Resolution with Cycle Detection
OhAPI resolves references across the spec (OpenAPI 3.x and Swagger 2.0) and safely handles circular references to avoid infinite recursion.
Native macOS, Document-Based Workflow
OhAPI behaves like a true macOS app:
•Open via File > Open, drag & drop, or Finder double-click
•Multiple documents in separate windows
•Recent files support
•Built-in examples to get started quickly
Formats & Compatibility
•File formats: .json, .yaml, .yml
•Versions: Swagger 2.0, OpenAPI 3.0.x, OpenAPI 3.1.x
•Light/Dark Mode and customizable node colors
Built with Swift and AppKit, OhAPI is designed to be fast, stable, and deeply integrated into macOS.
