Swagger & OpenAPI Studio

In Proxync v0.2.0, the Swagger Studio combines live traffic OpenAPI spec generation with an Automatic Multi-Framework Codebase Scanner.

Key Features in v0.2.0

• Multi-Framework Codebase Scanner — Automatically scans local codebase repositories (Express, Fastify, Next.js, NestJS, FastAPI, Spring Boot, Go) to infer endpoints and generate OpenAPI 3.0 definitions.
• Traffic-Driven JSON Schema Inferrer — Infers JSON parameter and response schemas dynamically from live intercepted traffic.
• Automatic Multi-Framework Codebase Scanner — Scans local project directories (Express, Fastify, Next.js App/Pages Router, NestJS, FastAPI, Spring Boot, Go Chi/Gin) and extracts routes into an OpenAPI 3.0 schema.
• Traffic-Driven Schema Inference — Merges live captured HTTP request/response payloads from Traffic Inspector to automatically populate missing OpenAPI request body and response schemas.
• 2-Way Collection Export/Import — Export OpenAPI specs directly into Playground collections or import existing OpenAPI YAML/JSON specs.
• Interactive OpenAPI UI & Spec Generator — Built-in visual API documentation viewer with instant YAML/JSON copy and download options.

Codebase Scanner Supported Frameworks

Framework	Scan Strategy
Express / Fastify	Inspects route registration (app.get, router.post).
Next.js	Scans app/api/**/route.ts and pages/api/**/*.ts.
NestJS	Parses @Controller() and HTTP method decorators (@Get, @Post).
FastAPI	Parses @app.get(), @app.post(), and Pydantic models.
Spring Boot	Parses @RestController, @GetMapping, @PostMapping.
Go (Gin/Chi)	Scans router definitions and handler signatures.

2-Way Playground Collection Sync

Clicking Export to Playground inside Swagger Studio automatically converts all endpoints into collection items and redirects seamlessly into Playground.
