🚀 Load Nexus

Load Nexus is a high-performance, professional-grade API load testing tool built for modern developers. Combining the safety and speed of Rust with the flexibility of a Tauri-based desktop interface, Load Nexus provides deep insights into your API's performance under heavy traffic.

✨ Features

• High Performance Engine: Powered by Rust's tokio and reqwest, ensuring minimal overhead and maximum throughput.
• Live Dashboard: Real-time visualization of latency percentiles (P50, P90, P99), RPS, and network throughput.
• Comprehensive Analytics: Track total hits, errors, average response times, and data transfer rates.
• Flexible Configuration: Supports GET, POST, PUT, DELETE methods with custom headers and body data (JSON, GraphQL, Form Data).
• File Upload Support: Seamlessly attach local files as multipart/form-data payloads, complete with custom field names and dynamic throughput calculation.
• Advanced Authentication: Seamlessly handle Bearer tokens and Basic Auth.
• Visual Excellence: Modern, glassmorphic UI with dynamic charts and responsive design.

🎯 Use Cases

• Stress Testing: Push your services to their limits to identify breaking points and bottleneck thresholds.
• Performance Benchmarking: Compare different implementations or versions of your API to ensure performance targets are met.
• CI/CD Validation: Run quick load tests locally or in staging environments before deploying to production.
• Network Analysis: Monitor network throughput and data transfer efficiency during high-concurrency scenarios.

🛠️ What Makes It Good for Testing?

Load Nexus isn't just another load tester; it's designed for clarity and speed:

1. Instant Feedback: Unlike CLI tools that only show results at the end, Load Nexus gives you live charts so you can see spikes and performance degradation in real-time.
2. Rust Efficiency: By using a multi-threaded Rust engine, it can simulate thousands of concurrent users with significantly lower CPU and memory usage than Node.js or Python-based alternatives.
3. Low Resource Footprint: As a native desktop app, it stays out of your way while providing a premium experience.
4. Actionable Metrics: Focuses on the metrics that matter—tail latencies (P95/P99) and error rates—rather than just "average" response times.

🏗️ Tech Stack

• Backend: Rust, Tauri
• Frontend: React, TailwindCSS, Vite
• Charts: Chart.js
• Icons: Lucide React
