LiteClient is a native VS Code extension that brings a powerful REST API client directly into your editor. No more context switching between your IDE and external tools. Make HTTP requests, manage environments, and organize your API collections without leaving VS Code.

​
Why LiteClient?

Modern API clients have become bloated with cloud accounts, telemetry, and features you never use. LiteClient returns to the fundamentals:

Zero startup time

Opens instantly with your workspace

Total privacy

All data stays local. No accounts, no telemetry, no cloud sync

Native UX

Uses VS Code’s native buttons, trees, and themes

Focused features

Everything you need, nothing you don’t

Core features

​
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.
