Connection status
Distinguish a successful connection from a timeout or authentication error. Format validation alone cannot confirm connectivity.

Your proxy list
One proxy per line. Up to 100 entries.
0 / 100 entries0 valid · 0 invalid · 0 duplicates
Supported formats & authentication
host:port or host:port:username:password
http://username:password@host:port
Also supports https://, socks5:// and bracketed IPv6 addresses. URL schemes override your selected protocol. Percent-encode special characters in URL credentials.

Test results
Your results will appear here
Explore an example report with connection status, exit IP, location and response time, or validate your list and run a live test when the service is online.
Response time
Compare request latency in milliseconds. Distance, destination and network load all affect results.
Exit IP & location
See the IP exposed to the test destination. Geolocation is approximate and can differ between databases.
A quick guide
How to test a proxy
1. Add your proxy list
Paste one endpoint per line or import a text file. Choose the protocol for entries without a URL scheme. A proxy URL with an explicit scheme keeps its own protocol.
2. Check the format
Validate the list to spot malformed endpoints, invalid ports and duplicate entries before making any connection. Format validation does not prove that a proxy is online.
3. Read connection results
Once live testing is available, successful connections can show the exit IP, location and response time. Authentication errors and timeouts will help identify what needs attention.
Proxy tester FAQs
Formats, protocols and what a proxy check can tell you.
How do I run a live proxy test?
Validate your list locally, then select Test proxies when the page shows Live testing online. A separate worker checks connectivity, response time and exit IP. If the service is offline, you can still validate formats and view clearly labelled example results.
Which proxy formats can I paste?
Use one proxy per line: host:port, host:port:username:password, or protocol://username:password@host:port. Explicit HTTP, HTTPS and SOCKS5 URL schemes take precedence over the selected protocol. Put IPv6 addresses in square brackets and percent-encode special characters in URL credentials.
How many proxies can I validate at once?
Each batch accepts up to 100 entries and 32 KB. Duplicate entries are removed. Live tests allow up to 5 batches per minute, 20 per 10 minutes and 2,000 proxy checks per hour per public IP, with one active batch at a time. Shared connections share these limits.
Are my proxy credentials uploaded?
Format validation runs locally without uploading your list. Starting a live test sends your endpoints and credentials to the testing service. Queue payloads are encrypted, expire after 15 minutes and are removed after processing. Credentials are never included in results or CSV exports, and the list is not saved in browser storage.
What is the difference between latency and proxy speed?
Latency measures the time a request takes to receive a response, usually in milliseconds. Download speed measures throughput over time. A short connectivity test measures response time, not a full bandwidth benchmark.
Does a working proxy work on every website?
No. A successful request confirms that the proxy reached the test endpoint at that moment. Other websites can apply their own IP restrictions, authentication requirements and geographic rules.
