Mjolnir The Ultimate Enterprise Load & Stress Testing Desktop Application An all-in-one desktop command center built for extreme scale, speed, and visual elegance.

---

🚀 Overview

Mjolnir is a state-of-the-art desktop server load and stress-testing application engineered to exceed the combined feature sets of industry-standard tools like k6, Apache JMeter, Locust, and Vegeta.

By uniting a 60 FPS React/Next.js Glassmorphism UI Control Plane with a compiled Rust asynchronous execution core, Mjolnir generates millions of requests per second across distributed cloud clusters without freezing or slowing down your desktop interface. Whether you are validating API rate limiters, evaluating cloud auto-scaling elasticity, or uncovering slow database connection pool leaks over multi-day soak tests, Mjolnir delivers an unmatched, dark-mode-first experience.

✨ Features

• ⚡ Extreme Rust Native Core: Powered by Tokio, Hyper, and Quinn. Executes high-concurrency HTTP/1.1, HTTP/2 multiplexing, HTTP/3 (QUIC/UDP), and persistent WebSockets with zero Garbage Collection pauses.
• 🎨 Visual Script Builder: Design complex, multi-step API stress workflows, configure custom headers, query parameters, auth tokens, and response assertions via intuitive drag-and-drop nodes—no coding required.
• 💻 Advanced Code Mode (JS/TS): Write dynamic load scripts using our embedded JavaScript runtime. Extract JWT tokens from login responses, execute conditional branching, and customize load variables on the fly inside the integrated Monaco editor.
• 📈 5 Enterprise Load Profiles:
  • Constant VU: Fixed concurrency for baseline throughput testing.
  • Ramping VU: Stepwise ramp up/down across time stages to simulate organic traffic surges.
  • Constant Arrival Rate: Target exact RPS guarantees for API rate-limiter stress testing.
  • Spike Testing: Instant traffic bursts to evaluate system elasticity and crash recovery.
  • Soak Testing: Multi-hour/day endurance testing to identify memory leaks and DB exhaustion.
• 🖥️ Remote SSH Host Monitoring: Connect directly to your target Linux/Unix backend server over SSH. Correlate live CPU utilization, Memory consumption, Load Average, Disk I/O, and Network interface bandwidth simultaneously alongside your stress histograms.
• 🌐 Distributed Cloud Cluster: Switch seamlessly between Standalone desktop testing, Master orchestration, and remote Worker daemon nodes to generate massive, multi-region cloud traffic.
• 📡 Observability Exporters: Stream sub-second latency percentiles (P50, P90, P95, P99) and error breakdowns directly into InfluxDB v2 and Datadog DogStatsD.
• 📊 Live 60 FPS Visualizations: Hardware-accelerated SVG and uPlot canvas charts tracking real-time requests per second, active virtual users, network bandwidth, and quantile latencies.

📥 Download & Install

Getting started with Mjolnir is fast and simple—no dependency compilation or CLI configuration required when using pre-built releases!

1. Download the Latest Release: Visit the official GitHub Releases page and download the package for your operating system:

   • Windows: Download Mjolnir-Setup-x.x.x.exe (Recommended) or the standalone portable executable Mjolnir-Portable-x.x.x.exe.
   • Linux: Download Mjolnir-x.x.x.AppImage or .deb.
   • macOS: Download Mjolnir-x.x.x.dmg or .zip.

2. Run Mjolnir: Launch the application and immediately start designing your stress scenarios or connecting to your cloud cluster!

Note

Important Note for Windows Users (Microsoft Defender SmartScreen): Because Mjolnir is an open-source application built without a paid corporate code-signing certificate, Windows Defender SmartScreen may display a "Windows protected your PC" popup when launching the installer or updating.

To proceed safely, simply click More info (under the text) → then click Run anyway. Mjolnir is 100% clean, transparent, and open-source!

🛠 Tech Stack

Mjolnir is engineered using a robust, hybrid desktop and systems technology stack:

• Framework: Electron for high-performance cross-platform desktop management.
• Frontend UI: React 18 + Vite for lightning-fast rendering and reactive state orchestration.
• Styling: Tailwind CSS featuring a curated dark-mode glassmorphism design system with custom HSL tokens and neon glows.
• Execution Engine: Compiled Rust binary (mjolnir-engine) utilizing tokio asynchronous runtimes, hyper HTTP libraries, and quinn QUIC transports.
• Charts & Visualization: uPlot canvas renderer for sub-millisecond data charting at 60 FPS.
• Scripting: Built-in Monaco Editor and embedded JavaScript execution runtime.
• Host Telemetry: Native ssh2 client for real-time Linux infrastructure monitoring.

🛠 Building from Source (For Developers)

If you would like to contribute or run Mjolnir locally from source code:

# 1. Clone the repository
git clone https://github.com/TheLunatic1/Mjolnir.git
cd Mjolnir

# 2. Install workspace dependencies
npx -y pnpm@latest install

# 3. Compile the native Rust stress engine
npm run build:engine

# 4. Start the full development workspace (Vite + Electron + Engine)
npm run dev

🎨 UI & Aesthetics

Mjolnir was designed from the ground up to feel premium, futuristic, and state-of-the-art. We discarded generic, boring form layouts in favor of a Dark Mode First aesthetic featuring vibrant cyan and primary accents, subtle micro-animations, glowing glassmorphic panels, and responsive hover interactions. The goal is to make enterprise load testing not just a routine QA check, but an exhilarating experience.
