I recently built and open-sourced a simple SOCKS5/HTTP proxy checking tool in Node.js, perfect for anyone managing proxy pools, web scraping, automation, or simply wanting to quickly test proxy health.
If you need to verify proxies, check latency, or screen for usable ones, give it a try! Source code is open, easy to deploy or extend.
Key Features
- One-click connectivity test for both HTTP and SOCKS5 proxies
- Geo location lookup for any proxy IP (integrated IP database)
- Curl check mode — simulates real curl requests via the proxy
-
Full support for username/password proxies (
user:pass@host:port) - CORS enabled — perfect for direct frontend or API integration
- Custom target support — test reachability to any site you choose
- IP info lookup endpoint for any IPv4
- Clear JSON results — human-readable, friendly for integration
- Easy to self-host, hack, or expand
Who Should Try This?
- Anyone with a proxy pool who needs fast filtering or ongoing health checks
- Web scraping engineers — batch proxy testing made easy
- Website developers, SEO/marketing, global outreach, or cloud ops teams
- Frontend devs who want an instant cross-origin proxy testing API
Project Experience
- Online demo: https://vrrul.com/en/socks5_proxy_detection
- Fast, simple Node.js backend; easy to run with Docker or locally
- Local IP-to-location DB — no third-party quota or delays
