YuliusBox is a privacy-first web toolkit offering client-side utilities like AI audio transcription, background removal, and PDF tools, with a newly added RDAP domain lookup and bulk availability checker. The domain tool leverages IANA's RDAP bootstrap for structured JSON data, includes SSRF protection and rate limiting, and handles bulk queries up to 50 domains. While the overall toolkit shows a broad scope, each individual tool is incremental rather than groundbreaking.

Target audience: web developers, devops, domain investors, privacy-conscious users
