Restify — API Client for VS Code

Restify is a powerful, lightweight, and professional REST API client built directly into VS Code. Stop switching between your editor and external tools—test your APIs exactly where you write your code.

🚀 Key Features

• Multi-Tab Support: Work on multiple requests simultaneously. Open an Auth request in one tab and your functional API in another side-by-side.
• Intelligent Variables: Use {{variable}} syntax in URLs, Headers, and Bodies.
• Live Variable Validation:
  • 🔵 Blue: Variable is correctly resolved from your active environment.
  • 🔴 Red: Variable is missing or misspelled.
• Hover Tooltips: Hover over any {{variable}} in the URL bar to see its real-time resolved value.
• Advanced Security (mTLS): Support for client certificates (.crt, .key, .ca) to connect to secure enterprise APIs.
• Proxy Integration: Full support for HTTP/HTTPS proxies with authentication and "No Proxy" bypass lists.
• Theme Aware: Automatically matches your VS Code theme (Dark, Light, High Contrast).
