1. Crypto & Security Tools

Crucial for authentication setup, payload verification, and security testing.

  • JWT Parser / Decoder: Decodes JSON Web Tokens (Header, Payload, and Signature) without transmitting secret keys over the internet.
  • Token & Password Generator: Generates cryptographically secure random passwords and API tokens with customizable character sets, lengths, and complexity rules.
  • Hash Text Generator: Computes cryptographic hashes (MD5, SHA-1, SHA-256, SHA-512) for strings to verify integrity or check signature matching.
  • Bcrypt Hash / Verifier: Hashes plain-text passwords or checks plain text against an existing hash using the bcrypt algorithm.
  • UUID / ULID Generator: Creates universally unique identifiers (v4 UUIDs) or time-sortable lexicographically sortable unique identifiers (ULIDs).
  • BIP39 Mnemonic Generator: Generates seed phrases and cryptographic keys used in wallet initialization and HD key generation.
  • RSA Key Pair Generator: Generates public and private RSA key pairs directly in the browser for local testing of asymmetric encryption systems.
  • Basic Auth Generator: Quickly constructs Authorization: Basic <base64> HTTP header credentials from a username and password.

2. Formatters & Prettifiers (Development)

Saves hours when dealing with messy logs, API responses, or raw system configurations.

  • JSON Prettify & Minify: Formats unformatted API JSON strings with customizable indentation or compresses them into a single line to reduce payload sizes.
  • JSON Diff: Highlights additions, deletions, and structural changes between two JSON payloads.
  • SQL Prettify: Formats raw SQL queries into clean, readable multi-line statements with capitalized keywords.
  • YAML / XML Formatter: Cleans up indentation, validates structure, and formats raw XML and YAML files.
  • Docker Run to Docker Compose: Translates single CLI flags (docker run -d -p 80:80 ...) into a structured docker-compose.yml file.
  • Cron Expression Generator & Parser: Provides human-readable schedules from crontab syntax (* * * * *) and generates cron strings based on selected intervals.
  • Chmod Calculator: Calculates Unix file permission flags visually (e.g., matching 755 or 644 to rwxr-xr-x).

3. Converters & Data Transformations

Eliminates manual scripts when translating data between standards.

Tool Common Developer Use Case
JSON ↔ YAML / TOML Converting configurations between framework standards (e.g., Kubernetes, Hugo, Node.js).
JSON ↔ CSV Exporting structured API responses directly into tabular formats for business analysis.
Base64 String & File Converter Encoding binary assets into strings for data URIs or decoding raw payload strings.
Integer Base Converter Converting numbers seamlessly between Binary, Octal, Decimal, and Hexadecimal.
Date / Timestamp Converter Converting Unix epoch timestamps (seconds/milliseconds) into ISO 8601 human dates and vice versa.
Case Converter Converting string variables between camelCase, snake_case, kebab-case, PascalCase, and CONSTANT_CASE.
Color Converter Translating color spaces between HEX, RGB, HSL, and CSS variable definitions.

4. Web & Network Utilities

Essential for API integration, network configuration, and SEO metadata debugging.

  • IPv4 Subnet Calculator: Calculates CIDR notation ranges, usable host ranges, broadcast addresses, and subnet masks.
  • URL Encoder / Decoder: Escapes parameters safely for query strings or decodes URI-encoded payloads (%20, %2F, etc.).
  • URL Parser: Breaks a complete URL down into protocol, host, port, path, parameters, and hash components.
  • Open Graph (OG) Meta Generator: Generates preview meta tags (og:title, og:image, twitter:card) for web page social media previews.
  • HTTP Status Codes Quick Reference: Detailed listing of response codes (1xx through 5xx) with descriptions of standard behavior.
  • User-Agent / Keycode Info: Inspects browser user-agent parameters and outputs JavaScript event.key / event.keyCode values for event listener development.

5. Text & Asset Generators

Quickly mock UI assets, data structures, and layout items without leaving the browser.

  • Lorem Ipsum Generator: Produces configurable placeholder paragraphs, words, or lists for UI prototyping.
  • QR Code & WiFi QR Generator: Generates downloadable vector/image QR codes for URLs, text, or automatic Wi-Fi network credentials.
  • SVG Placeholder Generator: Creates lightweight inline SVG image placeholders with dynamic dimensions and colors.
  • Text Diff / Statistics: Performs character-by-character or word-by-word diffs and calculates word count, character count, and reading time.
  • Slugify String: Converts raw article titles or strings into SEO-friendly web URL slugs (e.g., turning "Hello World!" into hello-world).

Key Architectural Strengths of IT-Tools

  1. Local Browser Processing (Zero Telemetry): Built as a client-side Single Page Application (Vue.js), meaning no confidential keys, credentials, or production payload fragments leave your local machine.
  2. Self-Hostable with Docker: Can be easily run locally on an internal network via containerization: 
docker run -d --name it-tools -p 8080:80 corentinth/it-tools:latest
Enter fullscreen mode Exit fullscreen mode
  1. Frictionless Workflow: Omnibox search allowing instant navigation across all 80+ tools using keyboard shortcuts.
