An easy to use open-source, multithreaded Proxy Checker. Allows you to quickly check HTTP and SOCKS proxies in a user friendly GUI, for Windows, Mac OS, Linux.
- GUI based
- Check HTTP, SOCKS4/4a and SOCKS5 Proxies
- Authenticated proxies (HTTP Basic, SOCKS5 username/password, SOCKS4 user id)
- Multithreaded & Multiplatform
- Filters and Removes Duplicate Proxies
- Ability to Load from multiple Proxy Lists
- Proxy Anonymity, Response Time & Country Information
- Export Table (CSV) and Export Based on Anonymity
- Stop a check at any time: the Check button becomes Stop and keeps the results gathered so far
- Command line mode for servers and scripts (no GUI required)
- Java 11+ (the packaged releases bundle JavaFX)
- Internet Connection :)
One proxy per line, in any of these formats:
203.0.113.10:8080
user:password@203.0.113.10:1080
203.0.113.10:1080:user:password
Passwords may contain : (and @ in the user:password@host:port form). Exports keep each proxy exactly as it was loaded, credentials included.
Simply download the latest packaged release for your system and run!
- Latest Release
- Windows (.exe), Mac OS (.dmg), Other (.jar)
Now also available on Docker Hub 🐳
While a check runs, the Check button becomes Stop. Stopping skips the proxies that haven't started,
closes connections that are in progress (no waiting for timeouts) and keeps every result already in the table.
The status bar then shows e.g. Checked Proxies: 4 of 14 (stopped, 10 not checked). The proxy input, the
loaded list (adding, deleting, drag and drop), File → Open… and Preferences… are disabled while checking, and
re-enabled when the check finishes or is stopped. Closing the window stops a running check too.
Run the same checker without the GUI (JavaFX is not initialised, so it works on headless servers):
java -jar ProxyChecker.jar --cli -i proxies.txt -t socks5 --threads 200 --timeout 5000 -o results.csv --only-working
cat proxies.txt | java -jar ProxyChecker.jar --cli -i - -q --only-working > working.txt
java -jar ProxyChecker.jar --help
| Option | Description |
|---|---|
-i, --input <file> |
proxy list, repeatable; - reads standard input |
-o, --output <file> |
write results to a file instead of standard output |
-f, --format txt|csv |
txt: one proxy per line as loaded; csv: all details. Defaults to csv for *.csv outputs |
-t, --type http|socks4|socks5 |
proxy protocol (default http) |
--threads <n> |
concurrent checks, 1-1000 (default 100) |
--timeout <ms> |
connect/read timeout, at least 500 (default 5000) |
-w, --only-working |
only output working proxies |
--my-ip <ip> |
your public IP (skips the lookup) |
--api-url <url> |
use another compatible proxy judge API |
-v, --verbose |
print the settings used and every proxy's result as it finishes, with the failure reason |
-q, --quiet |
no progress or summary on standard error |
-V, --version |
print the version; must be used on its own (combined with other options it's an error, as it's easily confused with -v) |
Progress and a summary are printed to standard error: a live progress line on a terminal, or a plain
Progress: ... line every 5 seconds when standard error isn't a terminal (pipes, log files, docker run without -t).
With -v each proxy is reported as soon as it finishes:
[WORKING] 1.0.133.89:4153 socks4 anonymous United States 812ms
[DEAD] 203.0.113.7:1080 socks4 connection refused
[DEAD] alice@203.0.113.9:1080 socks5 auth failed
Failure reasons include timeout, connection refused, auth failed, auth required, bad handshake,
rejected by proxy, bad HTTP response and bad API response. Passwords are never printed.
With Docker, arguments are passed straight to the application:
docker run --rm -v "$PWD:/data" faiqsohail/proxychecker --cli -i /data/proxies.txt -t socks4 -v -o /data/results.csv
Press Ctrl+C to stop early: in-flight checks are aborted, the proxies checked so far are still written
to the output, the summary says how many weren't checked, and the exit code is 130.
Exit codes: 0 working proxies found, 1 none working,
2 invalid arguments or no valid proxies in the input, 3 file or public IP lookup error,
130 interrupted with Ctrl+C.
Running the jar without arguments opens the GUI as before.
This assumes you have Java 11+ (JDK) and Maven set up correctly.
git clone https://github.com/faiqsohail/ProxyChecker.git
cd ProxyChecker
mvn package # compiles, runs the tests and builds target/ProxyChecker.jar
java -jar target/ProxyChecker.jar
During development you can also run the application directly with mvn javafx:run, or only the tests with mvn test.
Note: the jar bundles the JavaFX native libraries of the platform it was built on, so build it on the operating system you intend to run it on.
