An incredibly fast proxy checker & IP rotator with ease.

ContributingWhat's newDocumentationReport Issues


  • Proxy IP rotator: Rotates your IP address for every specific request.
  • Proxy checker: Check your proxy IP which is still alive.
  • All HTTP/S methods are supported.
  • HTTP, SOCKS v4(A) & v5 proxy protocols apply.
  • All parameters & URIs are passed.
  • Easy to use: You can just run it against your proxy file, and choose the action you want!
  • Cross-platform: whether you are Windows, Linux, Mac, or even Raspberry Pi, you can run it very well.

Why mubeng?

It's fairly simple, there is no need for additional configuration.

mubeng has 2 core functionality:

1. Run proxy server as proxy IP rotation

This is useful to avoid different kinds of IP ban, i.e. bruteforce protection, API rate-limiting or WAF blocking based on IP. We also leave it entirely up to user to use proxy pool resources from anywhere.

2. Perform proxy checks

So, you don't need any extra proxy checking tools out there if you want to check your proxy pool.



Simply, download a pre-built binary from releases page and run!


Pull the Docker image by running:

▶ docker pull


Using Go (v1.19) compiler:

▶ GO111MODULE=on go get -u
NOTE: The same command above also works for updating.

— or

Manual building executable from source code:

▶ git clone
▶ cd mubeng
▶ make build
▶ (sudo) mv ./bin/mubeng /usr/local/bin
▶ make clean


For usage, it's always required to provide your proxy list, whether it is used to check or as a proxy pool for your proxy IP rotation.

kitabisa mubeng


▶ mubeng [-c|-a :8080] -f file.txt [options...]


Here are all the options it supports.

▶ mubeng -h
Flag Description
-f, --file <FILE> Proxy file.
-a, --address <ADDR>:<PORT> Run proxy server.
-A, --auth <USER>:<PASS> Set authorization for proxy server.
-d, --daemon Daemonize proxy server.
-c, --check To perform proxy live check.
-g, --goroutine <N> Max. goroutine to use (default: 10).
--only-cc <AA>,<BB> Only show specific country code (comma separated).
-t, --timeout Max. time allowed for proxy server/check (default: 30s).
-r, --rotate <AFTER> Rotate proxy IP for every AFTER request (default: 1).
-m, --method <METHOD> Rotation method (sequent/random) (default: sequent).
-s, --sync Sync will wait for the previous request to complete.
-v, --verbose Dump HTTP request/responses or show died proxy on check.
-o, --output <FILE> Save output from proxy server or live check.
-u, --update Update mubeng to the latest stable version.
-w, --watch Watch proxy file, live-reload from changes.
-V, --version Show current mubeng version.


  • Rotations are counted for all requests, even if the request fails.
  • The proxy server runs asynchronously by default, so it doesn't guarantee that your requests after N (which is N+1 and so on) will rotate the proxy IP, instead use the -s/--sync flag to wait for requests to the previous proxy to complete.
  • Daemon mode (-d/--daemon) will install mubeng as a service on the (Linux/OSX) system/setting up callback (Windows).
    • Hence you can control service with journalctl, service or net (for Windows) command to start/stop proxy server.
    • Whenever you activate the daemon mode, it works by forcibly stop and uninstalling the existing mubeng service, then re-install and starting it up in daemon.
  • Verbose mode (-v/--verbose) and timeout (-t/--timeout) apply to both proxy check and proxy IP rotation actions.
  • HTTP traffic requests and responses is displayed when verbose mode (-v/--verbose) is enabled, but
    • We DO NOT explicitly display the request/response body, and
    • All cookie values in headers will be redacted automatically.
  • If you use output option (-o/--output) to run proxy IP rotator, request/response headers are NOT written to the log file.
  • A timeout option (-t/--timeout) value is a possibly signed sequence of decimal numbers, each with optional fraction and a unit suffix, such as "5s", "300ms", "-1.5h" or "2h45m".
    • Valid time units are "ns", "us" (or "µs"), "ms", "s", "m", and "h".

Install SSL Certificate

mubeng uses built-in certificate authority by GoProxy. With mubeng proxy server running, the generated certificate can be exported by visiting http://mubeng/cert in a browser.

Installation steps for CA certificate is similar to other proxy tools.


For example, you've proxy pool (proxies.txt) as:

Because we use auto-switch transport, mubeng can accept multiple proxy protocol schemes at once.
Please refer to documentation for this package.

Proxy checker

Pass --check flag in command to perform proxy checks:

▶ mubeng -f proxies.txt --check --only-cc AU,US,UK --output live.txt

The above case also uses --output flag to save a live proxy of specific country code with --only-cc flag (ISO-3166 alpha-2) into file (live.txt) from checking result.

(Figure: Checking proxies mubeng with max. 5s timeout)

Proxy IP rotator

Furthermore, if you wish to do proxy IP rotator from proxies that are still alive earlier from the results of checking (live.txt) (or if you have your own list), you must use -a (--address) flag instead to run proxy server:

▶ mubeng -a localhost:8089 -f live.txt -r 10 -m random

The -r (--rotate) flag works to rotate your IP for every N request value you provide (10), and the -m (--method) flag will rotate the proxy sequential/randomly.

(Figure: Running mubeng as proxy IP rotator with verbose mode)

Burp Suite Upstream Proxy

In case you want to use mubeng (proxy IP rotator) as an upstream proxy in Burp Suite, acting in-between Burp Suite and mubeng to the internet, so you don't need any additional extensions in Burp Suite for that. To demonstrate this:

(Figure: Settings Burp Suite Upstream Proxy to mubeng)

In your Burp Suite instance, select Project options menu, and click Connections tab. In the Upstream Proxy Servers section, check Override user options then press Add button to add your upstream proxy rule. After that, fill required columns (Destination host, Proxy host & Proxy port) with correct details. Click OK to save settings.

OWASP ZAP Proxy Chain

It acts the same way when you using an upstream proxy. OWASP ZAP allows you to connect to another proxy for outgoing connections in OWASP ZAP session. To chain it with a mubeng proxy server:

(Figure: Settings proxy chain connection in OWASP ZAP to mubeng)

Select Tools in the menu bar in your ZAP session window, then select the Options (shortcut: Ctrl+Alt+O) submenu, and go to Connection section. In that window, scroll to Use proxy chain part then check Use an outgoing proxy server. After that, fill required columns (Address/Domain Name & Port) with correct details. Click OK to save settings.

Proxy format

Currently mubeng supports HTTP(S) & SOCKSv4(A)/v5 protocol, see examples above. But, not limited by that we also support proxy string substitution and helper functions for your proxy pool.


If you have an authenticated proxy, you definitely don't want to write credentials constantly to the proxy pool file. mubeng can evaluate environment variable with {{VARIABLE}} writing style.

For example:

  1. String substitute
$ export USERNAME="FOO"
$ export PASSWORD="BAR"
$ echo "http://{{USERNAME}}:{{PASSWORD}}@" > list.txt
$ mubeng -f list.txt -a :8080
  1. Helper function

Available functions currently supported:

  • uint32, and
  • uint32n N.

Those following above functions are thread-safe pseudo-randomness.

As an example of its use, we will be utilizing stream isolation over Tor SOCKS. With this method, you just need one Tor instance and each request can use a different stream with a different exit node, but that doesn't guarantee that your ass will be rotated. Thus, we have to create unique USER:PASS pair to isolate streams for every connection. In order to pass pseudo-random proxy authorization, use uint32 or uint32n function on your proxy pool, like:

$ echo "socks5://{{uint32}}:{{uint32}}@" > list.txt
$ while :; do mubeng -f list.txt -c 2>/dev/null; done
[LIVE] [XX] [23.**.177.2] socks5://2123347975:3094119616@
[LIVE] [XX] [199.**.253.156] socks5://1646373938:2740927425@
[LIVE] [XX] [185.**.101.137] socks5://814036283:1382144874@
[LIVE] [XX] [185.**.83.83] socks5://2895805939:2276057153@
[LIVE] [XX] [103.**.167.10] socks5://408584795:1244204083@
[LIVE] [XX] [198.**.84.99] socks5://3015151335:251835794@
[LIVE] [XX] [179.**.159.197] socks5://3952852758:324998250@


Currently IP rotation runs the proxy server only as an HTTP protocol, not a SOCKSv4(A)/v5 protocol, even though the resource you have is SOCKSv4(A)/v5. In other words, the SOCKSv4(A)/v5 resource that you provide is used properly because it uses auto-switch transport on the client, but this proxy server DOES NOT switch to anything other than HTTP protocol.
