AllTools.dev is a modern, fast, free online toolkit built for people who need quick, accurate calculators and converters without signing up, creating an account, or wading through cluttered interfaces. The platform offers 500+ tools across finance (mortgage calculators, loan amortization, compound interest, currency conversion, debt payoff, retirement planning), health (BMI, calorie needs, pregnancy tracking, ideal weight, body composition), math (scientific, statistical, geometric, percentage, fraction), science and engineering, date and time utilities, unit conversions (volume, length, temperature, power, area), developer utilities (JSON, regex, JWT, hashing), and interactive math and algorithm visualizations. Every tool is free and works instantly in the browser. No accounts, no paywalls, no sign-in walls, no data collection beyond standard analytics. Calculations happen client-side for speed and privacy. Unlike older established calculator sites that grew through 20 years of ad-heavy layouts and outdated UX, AllTools.dev is built fresh on Astro with a clean, mobile-first, accessibility-conscious interface. New calculators ship weekly based on user demand. Ideal for: students doing homework, developers needing quick conversions, finance-minded folks planning loans and investments, professionals doing scientific or engineering calculations, and anyone who just needs a fast answer without installing an app.

Passgen features and specs

  • Simple and Lightweight
    Passgen is a straightforward, minimalistic password generator tool that doesn't come with unnecessary bloat. It focuses on doing one thing well — generating passwords — making it easy to understand and use.
  • Customizable Password Generation
    The tool allows users to customize password generation parameters such as length and character sets (uppercase, lowercase, digits, special characters), giving flexibility in creating passwords that meet different security requirements.
  • Command-Line Interface
    As a CLI tool, Passgen is convenient for developers and system administrators who prefer working in the terminal. It can be easily integrated into scripts and automation workflows.
  • Open Source
    Being hosted on GitHub as an open-source project, users can inspect the source code to verify there are no security vulnerabilities or backdoors, which is critical for a password generation tool.
  • No External Dependencies
    The project is built to be lightweight with minimal or no external dependencies, making it easy to install, deploy, and run across different environments without dependency conflicts.

Possible disadvantages of Passgen

  • Limited Community and Support
    As a relatively small open-source project, Passgen has a limited community of contributors and users. This means fewer bug reports, slower issue resolution, and less community-driven improvements compared to more popular alternatives.
  • Minimal Documentation
    The project's documentation is fairly basic, which may make it harder for new users to understand all available features or for contributors to get involved in development.
  • No GUI
    Passgen operates solely through the command line, which can be a barrier for non-technical users who would prefer a graphical user interface for generating passwords.
  • Limited Feature Set Compared to Alternatives
    Compared to more established password generators like pwgen or KeePass's built-in generator, Passgen offers a relatively limited set of features, lacking things like passphrase generation, entropy estimation, or password strength analysis.
  • Uncertain Maintenance Status
    The project may not be actively maintained with regular updates, which could be a concern for long-term reliability and security patching, especially for a security-related tool.
