Build a multi-container architecture visually — add services, wire up depends_on relationships, and export a real docker-compose.yml. Includes web+DB+cache and microservices+gateway starter templates.

Interactive Big-O time and space complexity reference for 27 algorithms and data structures — sorting, searching, graph traversal, trees, and hash tables. Filter by category, sort by complexity, with growth rate comparison chart.

Live regular expression tester with match highlighting, capture group display, and a 12-pattern library (email, IP, UUID, date, hex color, Docker image, env vars). JavaScript RegExp engine. Matches update as you type.

Decode and inspect JSON Web Tokens. View the header algorithm (HS256/RS256/ES256), all payload claims with human-readable timestamps, expiry status badge, and algorithm security guidance. 100% client-side — no data sent anywhere.
