OpenAPI Companion nga pratyanj

A browser extension that turns OpenAPI/Swagger docs into a persistent, productivity-focused API testing workspace.

Turn Swagger UI into a persistent, productivity-focused API testing workspace — completely offline and private.

Tired of re-entering authentication tokens after every page refresh, manually crafting test JSON payloads, or losing request parameters?

OpenAPI Companion integrates into Swagger UI via Chrome's native Side Panel, giving you a persistent workspace directly inside your API documentation.

1. PERSISTENT AUTHENTICATION
   • Retain authorization across page reloads without re-entering credentials.

3. MOCK DATA & DATASET STUDIO

4. Realistic: Production-like sample data.
5. Minimal: Generates only required fields.
6. Boundary: Tests maximum, minimum, and edge-case values.
7. QA & Security: Tests input handling with injection patterns and special character sets.
   • Bulk Dataset Generator: Create multi-row test datasets and export them directly as JSON or CSV files.
   • Live Fill: Auto-detects input fields in the open endpoint and fills empty parameters instantly.
8. REQUEST HISTORY & INSPECTION
