IT Utilities at your fingertips
The essential toolkit to simplify your daily workflow, right from your browser.
What problems do we solve and who do we empower daily?
At Arostik, we simplify the technical workflow of engineers, developers, sysadmins, and power users. We eliminate the friction of third-party downloads and slow installers: everything runs directly in your browser via native Web APIs with instant corporate-grade response.
Diagnostics and operations execute isolated inside your local device RAM sandbox, ensuring no private data, token, database query, or acoustic signal is ever transmitted to remote servers or stored in databases.
Zero Downloads or Installers
Direct instant access to professional diagnostics from any modern web browser and OS.
Total Privacy in Local RAM
Your data, tokens, SQL schemas, and acoustic signals never leave your local device memory.
Engineering-Grade Precision
Accurate telemetry for keycodes, real-time FFT audio, global DNS, and Ohm's Law equations.
Privacy by Design: Sandboxed In-Browser Processing
Each technical module leverages independent Web Workers and memory buffers. Real-time telemetry and privacy:
Hardware Telemetry & Sensor Capture
Micro-event capture for input peripherals and audio streams with millisecond precision.
$ arostik-sandbox --verify
✓ TLS_AES_256_GCM_SHA384 active
✓ RAM sandbox: 0 remote data leaks
✓ JWT & SQL parsed locally in RAM
Cryptography & Query Memory Isolation
JWT tokens, SQL code, and math calculations computed strictly locally in RAM.
Our tools suite in action
Online Keyboard Test
Comprehensively evaluates physical key switch response, simultaneous keypress combinations (anti-ghosting & N-Key Rollover), and exact actuation latency in milliseconds. Captures native DOM events in real-time with keycode telemetry without third-party drivers.
What is Aros Student?
An educational hub where we explain core IT concepts with clear analogies, real-world practical cases, technical glossaries, and an interactive quiz for each topic to validate your learning.
What is an API and How Does It Really Work?: The Waiter Analogy Explained
Learn what an API is from scratch: the customer, waiter and kitchen analogy, REST requests (GET, POST), status codes and authentication.
Relational vs. Non-Relational Database Fundamentals (SQL vs. NoSQL)
Understand the difference between strict tables and flexible JSON documents: ACID vs. BASE properties, vertical and horizontal scalability.
Help Center: Diagnostics, RAM Security & Metrics
Complete transparency regarding diagnostic Web APIs, RAM privacy guarantees, and supported technical workflows.
How do hardware diagnostics run directly in the browser without installing software?
Arostik leverages modern browser native APIs (Web Audio API, WebRTC, MediaDevices API, Gamepad API, Screen Capture API). These secure interfaces communicate directly with your peripherals inside the isolated browser sandbox, delivering instant precision metrics without binary downloads or admin rights.
Who benefits from these hardware diagnostic and network testing tools?
Our platform empowers IT support technicians to benchmark PCs; network engineers to inspect global DNS propagation and SSL certificates; software developers to format SQL or decode JWT; and engineering students to compute electronics problems instantly.
Is it safe to paste sensitive tokens or SQL scripts into Arostik?
It is 100% safe and confidential. Arostik enforces a strict Client-Side policy. Utilities parse data isolated using JavaScript inside your local device RAM. No code snippets, JWT tokens, or SQL queries are ever sent to remote servers or stored in databases.
What metrics are measured in connectivity, speed, and latency tests?
Our modules measure download and upload bandwidth in Mbps, round-trip latency (Ping in ms), jitter variance, public/private IP with ASN/ISP, HTTP security headers (HSTS, CSP), and mouse sensor polling rate in Hz.
