Check Your Proxies Online — Free
Test up to 5 proxies at once: alive status, speed, exit IP, location, ISP, fraud score and how they fare against Google, reCAPTCHA v3, Cloudflare Turnstile and more. No signup required.
Need more than 5?
Antybrowser's built-in bulk proxy checker tests unlimited proxies at once — with fraud scores, geo mismatch detection and one-click keeping of only the working ones.
How it works
1. Paste your proxies
Drop up to 5 proxy lines — HTTP, HTTPS, SOCKS4 or SOCKS5, with or without credentials.
2. Pick your checks
Choose exactly what to test: IP details, fraud score, Google access, or how the proxy fares against reCAPTCHA v3 and Cloudflare challenges.
3. Get instant results
See alive status, speed, exit IP, geo, ISP, fraud score and per-check verdicts — and share the report with your team.

Frequently asked questions
How many proxies can I check for free?
You can check up to 5 proxies per day for free, no account needed. Signed-in users get 10 per day. The limit resets at midnight UTC. If you need to check entire lists, Antybrowser's desktop app includes an unlimited bulk proxy checker on paid plans.
What proxy formats are supported?
HTTP, HTTPS, SOCKS4 and SOCKS5 proxies, with or without authentication: host:port, user:pass@host:port, socks5://host:port and the colon-separated variants the desktop app accepts.
What do the checks actually do?
Each selected check routes a real request through your proxy against the chosen target — an IP geolocation lookup, an IPQualityScore fraud lookup, a Google search, a reCAPTCHA v3 score check, a Cloudflare Turnstile challenge or a Cloudflare challenge page — and reports what happened, exactly like Antybrowser's built-in proxy checker.
Do you store my proxy credentials?
No. Credentials are only used to authenticate against the proxy during the check and are never stored in reports or logs. Share links only ever contain the sanitized results.
Why is my proxy dead when it works elsewhere?
The check runs from our servers, so geo-restricted or IP-allowlisted proxies may fail here while working for you. Trust the alive result for open proxies; a failure here usually means the proxy can't serve general traffic.
