Free Dev Utilities: Passwords, Placeholders, Timestamps & More
Generate passwords, create Lorem Ipsum text, convert timestamps, create UUIDs, and convert colors. Handy free tools for everyday dev tasks.
Day-to-day dev work often needs random passwords, placeholder text, timestamps, unique IDs, and color codes. Instead of scripting one-off solutions or hunting for sites, you can use a single set of free browser-based utilities. Here's a roundup of tools that cover passwords, Lorem Ipsum, timestamps, UUIDs, and color conversion.
Generate Strong Passwords
Creating secure passwords for dev accounts, API keys, or test users is easier with a password generator that uses the browser's crypto API. Choose length and character types (uppercase, lowercase, numbers, symbols), generate one or several passwords, and copy. No server, no storage—just random passwords on demand.
Placeholder Text with Lorem Ipsum
When you need filler text for layouts or demos, a Lorem Ipsum generator produces paragraphs, sentences, or words. Set the count, copy, and paste into your mockups or docs. Simple and fast for wireframes and UI testing.
Convert Unix Timestamps
APIs and databases often use Unix timestamps. A timestamp converter turns seconds or milliseconds into human-readable dates and vice versa. Handy for debugging time-based logic, log analysis, or converting between systems. Shows both local time and UTC.
Create UUIDs
Unique identifiers are common in apps and databases. A UUID generator creates cryptographically random UUIDs (e.g. v4). Generate one or many at once for seeding data, testing, or assigning IDs. Copy a single UUID or the whole list.
Convert Color Formats
Switching between HEX, RGB, and HSL is routine in front-end work. A HEX to RGB color converter converts between these formats and shows a live preview. Enter a hex code or RGB values and get the equivalent in other formats—useful for CSS, design handoffs, and theme tweaks.
Conclusion
Passwords, placeholders, timestamps, UUIDs, and colors come up all the time in development. Free online utilities for these tasks run in your browser with no signup and no data sent to servers. Keep this set bookmarked for quicker, safer workflows.
