Is QuickVPN Proxy – VPN for Browsing safe?

QuickVPN Proxy is a low-risk freemium VPN extension that routes browser traffic through Webshare.io datacenter proxies. While the extension's core VPN functionality is legitimate and serves its intended purpose, it exhibits architectural security concerns including an exposed API key retrieval endpoint (Cloudflare Workers serving shared Webshare API keys to all users) and insecure credential storage in local storage. The extension does NOT engage in malicious behavior, data exfiltration, ad injection, or residential proxy fraud. All permissions are appropriate for VPN functionality. The main security issue affects the developer's infrastructure (API quota abuse risk) rather than end users. Monetization is transparent via Gumroad licensing with a 3-day trial. Rating: LOW (not CLEAN due to API key architecture, but not malicious).
