Tools Hub
Developer tools for the moments when raw data and unreadable output slow you down
This index is built around repeat engineering jobs: inspect a token, validate a payload, convert an epoch value, generate a QR code, test a regex, or clean up encoded data before the work moves back into code, docs, or incident review.
Payloads
Debug data before you debug code
Use the JSON formatter, Base64 tool, URL encoder, and regex tester when an API response or log line is unreadable enough to hide the real bug.
Auth And Time
Read claims, epochs, and expiry windows quickly
JWT and timestamp tools work best together when a 401, webhook failure, or audit trail turns into a question about claims, timezones, or seconds versus milliseconds.
Sharing
Create QR handoffs for links, Wi-Fi, and docs
Use the QR generator when builds, docs, release notes, or support assets need mobile scanning without adding redirect infrastructure.
Primary Tools
Clean, production-facing tool pages
This hub intentionally excludes debug, fixed, and alternate variants. Only the main routes that should earn links, rankings, and repeat usage are included.
QR Code Generator
Generate QR codes for URLs, text, Wi-Fi, and contact cards with download-ready output.
Password Generator
Generate strong passwords with configurable length, symbols, exclusions, and multi-copy output.
JSON Formatter
Format, validate, minify, and inspect JSON payloads for APIs and debugging work.
Base64 Encoder & Decoder
Encode and decode Base64 or URL-safe payloads without leaving the browser.
Hash Generator
Generate MD5, SHA-family, CRC, and Adler hashes for integrity and verification tasks.
JWT Decoder
Decode JWT headers and payloads, inspect claims, and read expiration timestamps.
UUID Generator
Generate one or many RFC-compliant UUID v4 values for APIs, databases, and jobs.
Timestamp Converter
Convert Unix timestamps to readable dates and back with timezone-aware output.
Regex Tester
Test patterns, toggle flags, and highlight all matches against live input.
URL Encoder / Decoder
Encode query values and decode percent-escaped URLs for API and redirect debugging.
Color Palette Generator
Create monochromatic, analogous, triadic, and complementary palettes for product and UI work.
Lorem Ipsum Generator
Generate placeholder paragraphs, sentences, words, lists, and article-length filler copy.
Strong Guides
Recommended reads when the tool alone is not enough
Format API Responses with a JSON Formatter Online
A practical guide to malformed payloads, validation failures, and faster API debugging.
How to Read JWT Expiration Time with a JWT Decoder
Useful when auth debugging turns into a question about exp, iat, nbf, and clock drift.
Create a QR Code for a URL, WiFi, or Contact Card
