NitroHttp v1.0.0 – Initial Stable Release

Lightweight API Client for Fast Request/Response Debugging

NitroHttp is a modern desktop API testing tool built with Avalonia and .NET, designed for developers who need a clean and fast workflow for sending HTTP requests and inspecting responses.

This release focuses on practical day-to-day API debugging with a structured request builder, response analysis panel, and local request persistence.

What’s Included

Request Builder

• HTTP methods: GET, POST, PUT, PATCH, DELETE
• URL input with query parameter synchronization (key/value rows are automatically reflected in the URL)
• JSON request body editor with syntax highlighting and line numbers
• Dedicated tabs for Body, Params, Headers, and Auth input workflows

Response Analysis

• Status display with full HTTP code/message mapping (including color-coded success/redirect/client/server states)
• Response metrics: item count, elapsed time, and response size
• Response tabs for Body, Headers, and Cookies
• Pretty-printed JSON responses when valid JSON is returned
• Built-in loading overlay while requests are in progress

State, History, and Collections

• Automatic request history tracking with duplicate de-duplication
• History limit management (keeps recent items for quick recall)
• Save current requests into named Collections
• Rehydrate requests from History/Collections (method, URL, body)
• Persistent local storage in app data (requests.json) so sessions survive app restarts

Platform and Runtime

• Cross-platform desktop app using Avalonia (Linux/Windows/macOS)
• .NET runtime with HttpClient pipeline and cookie container support for cookie-aware testing

Ideal Use Cases

• Testing REST endpoints during backend/frontend development
• Quickly verifying request payloads and response contracts
• Replaying commonly used API calls from collections
• Inspecting headers/cookies during authentication and session flows

Platforms Supported

• Linux
• Windows
