API Spector

API Spector is a lightweight, local API monitoring and payload inspection tool. Designed for developers and QA engineers, it intercepts outbound HTTP/HTTPS requests from localhost, parses raw payloads, and visualizes schemas in a modern browser dashboard.

Key Features of API Spector

• Local Traffic Interception: Captures API requests from web applications, backend services, and CLI tools.
• JSON Schema Visualizer: Automatically converts raw JSON request and response payloads into readable tree graphs.
• Payload Diffing: Compare request bodies side-by-side to debug state change variations.
• Instant Mock Generation: Turn captured API responses into mock files with a single click.

Benefits of Using API Spector

• Fast API Debugging: Skip checking system log terminal streams; view structured API layouts in real-time.
• Mock Server Integration: Quickly create mock data to keep frontend developer tasks moving when endpoints go down.
• No-Config Proxying: Simple startup parameters let you capture traffic without changing system-wide proxy profiles.

QA engineers working on local API debugging can use API Spector to capture, inspect, and mock HTTP/HTTPS traffic, facilitating quick frontend-backend integration verification.
