Collections and organization
Organize your API requests in a hierarchical structure that grows with your project. Create unlimited collections to group related APIs, nest requests inside folders for logical organization, and use drag-and-drop reordering to keep things organized.Environment management
Manage different configurations for local, staging, and production environments. Create named environments with structured variables, use global variables available across all environments, and enjoy layered variable resolution that follows a clear precedence: Globals → Collection → Environment.Complete authentication support
LiteClient supports the authentication methods you need:- API Key - Custom header or query parameter placement
- Bearer Token - Simple token-based authentication
- Basic Auth - Username/password with automatic Base64 encoding
- OAuth 2.0 - Authorization Code, Authorization Code with PKCE, and Client Credentials flows with automatic token caching and refresh
Privacy first
LiteClient is designed with privacy as a core principle. All data is stored locally in VS Code’s global storage or optionally in your workspace’s.liteclient/ folder. No telemetry, no analytics, no tracking, and no cloud sync. Your API keys and credentials are stored locally—only you can access them.
