IT Utilities at your fingertips
The essential toolkit to simplify your daily workflow, right from your browser.
Online Keyboard Test
Tests physical key response, simultaneous combinations (anti-ghosting) and latency. Outputs JavaScript keycodes, keypress events and active key mapping.
Microphone Test
Analyzes real-time audio capture and frequency response. Outputs gain levels in decibels (dB), FFT spectrum and sample rate in Hz.
Speaker & Sound Test
Verifies acoustic fidelity and stereo separation for speakers or headphones. Generates sine frequencies from 20 Hz to 20 kHz and L/R channel balance.
Webcam Diagnostics Test
Diagnoses connected video sensors and webcams. Measures maximum native resolution (HD/4K), frames per second (FPS) and exposure balance.
Screen & Pixel Test
Inspects LCD, OLED and IPS panel integrity. Projects solid color and contrast patterns to detect dead pixels, burn-in or backlight bleed.
Mouse & Sensor Test
Evaluates optical/laser sensor precision, click switches and scroll wheel. Outputs Polling Rate (Hz), clicks per second (CPS) and tracking jitter.
System Hardware Info
Extracts hardware specifications and runtime environment. Detects CPU cores, available RAM, rendering GPU, architecture and operating system.
Display Specifications
Detects display configuration for primary and secondary monitors. Measures actual/available resolution, pixel density (DPI), aspect ratio and color depth.
CPU/GPU Stress Test
Subjects CPU and graphics pipeline to extreme computational loads. Evaluates thermal stability, throttling and multithreaded performance.
Battery Health & Stress Discharger Pro
Li-ion cell diagnostics, BMS calibration, and accelerated stress discharger with multithread Web Workers and real-time telemetry.
Internet Speed Test
Measures comprehensive network link performance. Outputs download and upload speeds in Mbps, ping latency in milliseconds and jitter fluctuation.
My LAN IP & Local Network
Inspects your local network (LAN) in real time: discovers your private IP, subnet mask, default gateway, local DNS servers, and WINS/NetBIOS status.
Public IP & Network Info
Identifies WAN IP address and network geolocation. Displays IPv4/IPv6 address, Internet Service Provider (ISP), Autonomous System (ASN) and city.
SSL Certificate Auditor
Inspects domain TLS/SSL trust chain and encryption. Evaluates Certificate Authority (CA), cipher suites, TLS version and expiration date.
DNS & Mail Inspector
Queries global DNS zone records and email security protocols. Extracts A, AAAA, MX, CNAME, TXT records and validates SPF, DKIM and DMARC policies.
IPv4 Subnet Calculator (CIDR)
Calculates IPv4 network addressing and segmentation. Determines subnet mask, broadcast address, usable host ranges and CIDR notation.
Domain WHOIS Lookup
Retrieves domain registration and delegation data. Outputs accredited registrar, creation/expiration dates, EPP domain status and nameservers.
HTTP Security Headers Auditor
Analyzes security directives sent by web servers. Evaluates HSTS, CSP, X-Frame-Options, CORS headers and HTTP response timing.
Global DNS Propagation Mapper
Checks global DNS record propagation in real time across resolvers in 20+ countries with interactive world map and latency telemetry.
JWT Token Decoder
Inspects and validates JSON Web Tokens client-side. Breaks down algorithm headers, JSON payload claims and signature validity.
Regex Tester & Validator
Evaluates regular expressions against test strings in real time. Highlights matches, capture groups and calculates processing execution time.
UUID / ULID Generator
Generates cryptographically secure universal unique identifiers. Creates UUID v4, v1 and time-sortable ULIDs in standard and bulk formats.
SQL Formatter & Beautifier
Beautifies and standardizes SQL query syntax. Applies indentation, keyword capitalization and formats clauses for MySQL, PostgreSQL, Oracle and SQL Server.
CSV to SQL Converter
Converts tabular datasets into ready-to-run SQL queries. Infers data types (VARCHAR, INT, FLOAT) and generates batch INSERT INTO statements.
SQL Schema Generator
Models relational database structures. Generates CREATE TABLE DDL code with primary keys, foreign keys, indexes and integrity constraints.
Resistor Color Code Calculator
Decodes ohmic resistance through standard color codes. Calculates nominal resistance, percentage tolerance and temperature coefficient for 4, 5 and 6 bands.
Ohm's Law Calculator
Solves fundamental DC/AC electrical circuit equations. Calculates voltage (V), current (I), resistance (R) and dissipated power in watts (W).
LED Resistor Calculator
Determines current-limiting resistor values for light-emitting diodes. Calculates ohm values, power dissipation (W) and prevents thermal overload.
