Reqlight

A lightweight, cross-platform HTTP client built with Tauri.

Reqlight is a fast, minimal alternative to Postman. No login required. Fully offline. Your data stays local.

Features

• HTTP Requests — GET / POST / PUT / PATCH / DELETE / HEAD / OPTIONS with query params, headers, and multiple body types (JSON, Form Data, Multipart, Raw Text)
• GraphQL — Dedicated query and variables editor with syntax support
• WebSocket — Connect with custom headers, auto-reconnect with exponential backoff, environment variable interpolation
• Authentication — Bearer Token, Basic Auth, API Key, OAuth 2.0 (Client Credentials & Authorization Code with PKCE)
• Collections — Organize requests into folders, rename, duplicate, drag to reorder
• Collection Runner — Execute all requests sequentially with assertion-based pass/fail, variable chaining, and scripting integration
• Assertions — Declarative response validation rules: status code, response time, headers, JSONPath, body contains
• Scripting Engine — Pre-request and test scripts powered by QuickJS — set env vars, compute auth tokens, validate responses with rl.test() / rl.expect()
• CLI Runner — Headless reqlight-cli for CI/CD with --collection, --env, --junit, --data, --fail-fast flags
• Environment Variables — Multiple environments (dev / staging / prod), {{variable}} interpolation everywhere, built-in dynamic variables ($timestamp, $guid, etc.)
• Response Variable Extraction — Define JSONPath rules (with wildcard and recursive descent) to extract values from responses into environment variables
• Code Generation — Export requests as JavaScript (fetch / axios), Python (requests), or cURL
• Import / Export — cURL, Postman collections & environments, OpenAPI 3.x specs, HAR files
• Response Diff — Pin a response and compare side-by-side with the latest result
• Proxy Settings — Configurable HTTP proxy with URL and no-proxy list
• Secure Storage — Sensitive values stored in OS keychain (macOS Keychain / Windows Credential Manager)
• Request History — Last 100 requests with status, timing, and link back to source request
• Dark / Light Theme — Follows system preference, or toggle manually
• Keyboard Shortcuts — ⌘↩ Send, ⌘N New Request, ⌘⇧N New Collection, ⌘E Environments
