Bulk Proxy Checker
Built for lists, not single proxies. Paste your list and the free web tool checks 50 at a time, giving you real alive/dead status, latency, country, ISP, and datacenter-vs-residential type for every one. Nothing to install and no account. If your list runs longer than the free allowance, your input stays exactly where it is and you can pick up the rest from there.
Live checking is discontinued
ProxyChecker.dev no longer runs proxy checks, the API, MCP tools or paid plans. Nothing on this site tests a proxy anymore. The guides below still explain how proxy testing works and what to look for.

Frequently asked questions
What happens if I paste more than 50 proxies?
The free tier checks the first 50 and shows you real results for those, then a $5 one-time pack covers the rest of the list, with no subscription.
Can I export results to CSV?
Yes, with a paid API key. Add format=csv to your /api/check request and get the same results as a downloadable CSV instead of JSON, ready for a spreadsheet or script.
How fast is a bulk check?
Checks run concurrently in a worker pool, not one at a time. Free tier runs 20 at once, Pro runs 50 at once, and Business runs 75 at once, so a 5,000-proxy list on Pro finishes in a fraction of the time a sequential checker would take.
Do I need to sign up to check a large list once?
No. The $5 one-time pack covers 5,000 validations with no account and no recurring charge, which is the fastest path if this is a one-off job.
