Twitch Username Generator

This streaming identity tool generates Twitch-compliant usernames by combining curated word banks organized into four distinct style categories: Gaming (aggressive, competitive terms), Funny (humorous food and adjective combinations), Pro Streamer (professional broadcasting vocabulary), and Aesthetic (calm, nature-inspired terminology). Each category maintains 28-32 unique prefixes and suffixes producing over 900 possible combinations per style before keyword integration.

The algorithm enforces Twitch platform requirements: usernames contain only ASCII letters, digits, and underscores, measure between 4 and 25 characters, and exclude prohibited special characters. Keyword integration weaves user-supplied terms into generated patterns, randomly positioning them as prefix bases or suffix anchors combined with category-appropriate modifiers. Optional numeric suffixes (1-999) add uniqueness while maintaining readability.

Username construction follows proven patterns: {StylePrefix}{Separator}{Keyword}{Number} or {Keyword}{Separator}{StyleSuffix}{Number}, where separators alternate between underscores and direct concatenation. The deduplication engine ensures batch results contain no repeated entries by maintaining a Set structure during generation. Length control via slider constrains maximum character count, automatically truncating overlong combinations while preserving minimum 4-character validity. Results display character counts alongside each username for quick Twitch registration planning.
