API Spector is a free, open-source API testing tool designed to help developers inspect, test, and mock APIs securely. It allows users to send requests, run contract tests, monitor APIs, and manage encrypted secrets locally without compromising data privacy.

Key Features:

Send API requests and mock responses directly from the desktop app or command line.
Run automated contract tests to prevent breaking changes with a Pact-compatible broker and deploy gate.
Encrypt sensitive data using AES-256-GCM, ensuring secure storage and transmission of secrets.
Integrate seamlessly with external secret managers like HashiCorp Vault, AWS Secrets Manager, and Azure Key Vault.
Work efficiently in CI/CD pipelines by referencing encrypted secrets without storing them in plain text.

Target Audience and Benefits:

Ideal for developers, QA engineers, and API teams seeking reliable testing and contract management. The tool’s local-first approach ensures data stays private while supporting secure integration into automated workflows. Available via WinGet, users can install and deploy the application easily using the command line.
