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 Unlike older established calculator sites that grew through 20 years of ad-heavy layouts and outdated UX, AllTools.dev is built fresh on Astro with a clean, mobile-first, accessibility-conscious interface.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.

Prettier mentions (305)

  • Readability in the age of AI-assisted programming
    Prettier - an opinionated code formatter for many languages, including TypeScript and JavaScript. - Source: dev.to / 9 days ago
  • Visual friction in development
    Line length, spacing, and indentation matter. My preference for code is roughly 80 to 110 characters. Longer lines become tiring to scan, while very short lines can create excessive wrapping. For formatting, tools like Prettier reduce debate and keep code visually consistent across contributors. - Source: dev.to / about 2 months ago
  • How to Build a Dependency Map of a Legacy Codebase Using AI Tools
    137Foundry provides legacy modernization services that include dependency mapping as a foundational assessment phase. Prettier and ESLint are useful companion tools for enforcing code style consistency as the refactoring proceeds. Node.js and Python.org official documentation are authoritative references for understanding the import and module systems of those runtimes. - Source: dev.to / 4 months ago
  • How to Prepare a Legacy Codebase for AI-Assisted Refactoring
    Prettier and ESLint are useful tools for establishing consistent code style as a baseline before starting structural refactoring - style differences in a diff make behavioral changes harder to spot. OWASP provides useful checklists for security-critical code review that apply directly to the critical path review step. - Source: dev.to / 4 months ago
  • How I Automated My Entire Claude Code Workflow with Hooks
    The matcher field takes a regex pattern. Edit|Write means this hook only fires when the Edit or Write tool is used. Claude running Bash, Read, or any other tool won't trigger it. The command itself uses jq to extract the file path from the tool input JSON, then pipes it to Prettier. Every file Claude touches gets formatted automatically. - Source: dev.to / 5 months ago
