# Generators - 37 Free Online Tools > Generate passwords, QR codes, UUIDs, hashes, random numbers, and more. Create secure, unique, standards-compliant outputs instantly in your browser. Browse all 37 free online generators on DevTools Hub. URL: https://tools.scoreroute.com/tools/generators/ ## Frequently Asked Questions **What types of generators are available?** Thirty-five generators across categories: security (password, UUID, hash, random), codes (QR, barcode, bingo card), web (favicon, meta tags, schema markup, slug, email signature, HTML table, lorem ipsum), CSS (gradient, box shadow, animation, flexbox, grid), design (chart maker, mock data, mermaid diagram, fancy text, Venn diagram), puzzles (sudoku, wordle, connections, snake, solitaire, chess move validator), lottery numbers, cron expressions, and more. **Are the generated passwords and UUIDs truly random?** Yes. The password generator uses crypto.getRandomValues() for cryptographically secure randomness — the same source browsers use for TLS. UUID v4 generates 122 random bits per RFC 4122. UUID v7 is time-ordered. Hash generator runs SHA-1/256/512 on your input. All randomness is sourced from the OS entropy pool, not Math.random(). **Are the CSS generators suitable for production code?** Yes. The CSS gradient, box shadow, animation, flexbox, and grid generators output production-ready CSS with standard syntax, vendor prefixes where needed, and no inline style bloat. Each generator provides a live preview so you can iterate visually before copying the final code. **Can I use the puzzle games offline?** Sudoku, Wordle, Connections, Snake, and Solitaire all run client-side with no network requests after the initial page load. They use localStorage to persist game state (scores, streaks, daily puzzles) even when offline. Chess move validator checks all legal moves per standard FIDE rules in your browser. ## Tools in this category - [Bingo Card Generator - Free Printable](https://tools.scoreroute.com/tools/bingo-card-generator/): Free printable bingo card generator. 1-75, 1-90, or custom themed. 100% free, no signup, no watermark, no upload.
