How it works
CloudProxy starts a proxy server and it waits for user requests in an idle state using few resources. When some request arrives, it uses puppeteer with the stealth plugin to create a headless browser (Chrome). It opens the URL with user parameters and waits until the Cloudflare challenge is solved (or timeout). The HTML code and the cookies are sent back to the user and those cookies can be used to bypass Cloudflare using other HTTP clients.
NOTE: Web browsers consume a lot of memory. If you are running CloudProxy on a machine with few RAM, do not make many requests at once. With each request a new browser is launched unless you use a session ID which is strongly recommended. However, if you use sessions, you should make sure to close them as soon as you are done using them.
Installation
It requires NodeJS.
Run PUPPETEER_PRODUCT=chrome npm install to install CloudProxy dependencies.
Usage
First run npm run build. Once the TypeScript is compiled, you can use npm start to start CloudProxy.
Example request:
curl -L -X POST 'http://localhost:8191/v1' \
-H 'Content-Type: application/json' \
--data-raw '{
"cmd": "request.get",
"url":"http://www.google.com/",
"userAgent": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.0 Safari/537.36",
"maxTimeout": 60000,
"headers": {
"X-Test": "Testing 123..."
}
}'Commands
+ sessions.create
This will launch a new browser instance which will retain cookies until you destroy it
with sessions.destroy. This comes in handy so you don't have to keep solving challenges
over and over and you won't need to keep sending cookies for the browser to use.
This also speeds up the requests since it won't have to launch a new browser instance for every request.
| Parameter | Notes |
|---|---|
| session | Optional. The session ID that you want to be assinged to the instance. If one isn't set a random UUID will be assigned. |
| userAgent | Optional. Will be used by the headless browser. |
+ sessions.list
Returns a list of all the active sessions. More for debuging if you are curious to see how many sessions are running. You should always make sure to properly close each session when you are done using them as too many may slow your computer down.
Example response:
{
"sessions": [
"session_id_1",
"session_id_2",
"session_id_3..."
]
}+ sessions.destroy
This will properly shutdown a browser instance and remove all files associaded with it to free up resources for a new session. Whenever you no longer need to use a session you should make sure to close it.
| Parameter | Notes |
|---|---|
| session | The session ID that you want to be destroyed. |
+ request.get
| Parameter | Notes |
|---|---|
| url | Mandatory |
| session | Optional. Will send the request from and existing browser instance. If one is not sent it will create a temporary instance that will be destroyed immediately after the request is completed. |
| headers | Optional. To specify user headers. |
| maxTimeout | Optional. Max timeout to solve the challenge |
| cookies | Optional. Will be used by the headless browser. Follow this format |
| encode | Optional. Add to header list 'Content-Type': 'application/x-www-form-urlencoded' — can be useful if you need to send a JSON in postData. |

}+ request.post
This is the same as request.get but it takes one more param:
Example request:
curl -L -X POST 'http://localhost:8191/v1' \
-H 'Content-Type: application/json' \
--data-raw '{
"cmd": "request.post",
"url":"http://www.google.com/",

"maxTimeout": 60000,
"postData": { "string": "string", "number": 10, "boolean": false },
"headers": {
"X-Test": "Testing 123..."
}
}'| Parameter | Notes |
|---|---|
| postData | Must be a object. |
Downloading Images and PDFs (small files)
If you need to access an image/pdf or small file, you should pass the download parameter to
request.get setting it to true. Rather than access the html and return text it will
return a the buffer base64 encoded which you will be able to decode and save the image/pdf.
This method isn't recommended for videos or anything larger. As that should be streamed back to the client and at the moment there is nothing setup to do so. If this is something you need feel free to create an issue and/or submit a PR.
Environment variables
To set the environment vars in Linux run export LOG_LEVEL=debug and then start CloudProxy in the same shell.
| Name | Default | Notes |
|---|---|---|
| LOG_LEVEL | info | Used to change the verbosity of the logging. |
| LOG_HTML | false | Used for debugging. If true all html that passes through the proxy will be logged to the console. |
| PORT | 8191 | Change this if you already have a process running on port 8191. |
| HOST | 0.0.0.0 | This shouldn't need to be messed with but if you insist, it's here! |
| CAPTCHA_SOLVER | None | This is used to select which captcha solving method it used when a captcha is encounted. |
| HEADLESS | true | This is used to debug the browser by not running it in headless mode. |
Captcha Solvers
Sometimes CF not only gives mathmatical computations and browser tests, sometimes they also require the user to solve a captcha. If this is the case, CloudProxy will return the captcha page. But that's not very helpful to you is it?
CloudProxy can be customized to solve the captcha's automatically by setting the environment variable
CAPTCHA_SOLVER to the file name of one of the adapters inside the /captcha directory.
CaptchaHarvester
This method makes use of the CaptchaHarvester project which allows users to collect thier own tokens from ReCaptcha V2/V3 and hCaptcha for free.
To use this method you must set these ENV variables:
CAPTCHA_SOLVER=harvester
HARVESTER_ENDPOINT=https://127.0.0.1:5000/tokenNote: above I set HARVESTER_ENDPOINT to the default configureation
of the captcha harvester's server, but that could change if
you customize the command line flags. Simply put, HARVESTER_ENDPOINT
should be set to the URI of the route that returns a token in plain text when called.
hcaptcha-solver
This method makes use of the hcaptcha-solver project which attempts to solve hcaptcha by randomly selecting images.
To use this solver you must first install it and then set it as the CAPTCHA_SOLVER.
npm i hcaptcha-solver
CAPTCHA_SOLVER=hcaptcha-solverOther Options
Everyone likes more options to choose from. Help contribute to the projects by submitting PR requests for other 3rd party captcha solves or your own projects. PR's are welcome for any and all captcha solving methods and services.
Docker
You may edit the ./Dockerfile as well as ./docker-compose.yml as you see fit.
# To build the image & run it using `docker compose` (detched mode)
docker compose up -d
# To stop & remove containers:
docker compose down
# You may also build and run manually, however the configuration is
# already set in the compose file, that way you dont have to remember it.
docker build -t cloudproxy:latest .
docker run --restart=always --name cloudproxy -p 8191:8191 -d cloudproxy:latestTypeScript
I'm quite new to TypeScript. If you spot any funny business or anything that is or isn't being used properly feel free to submit a PR or open an issue.
Known issues / Roadmap
The current implementation seems to be working on the sites I have been testing them on. However, if you find it unable to access a site, open an issue and I'd be happy to investigate.
That being said, the project uses the puppeteer stealth plugin. If Cloudflare is able to detect the headless browser, it's more that projects domain to fix.
TODO:
- Fix remaining issues in the code (see TODOs in code)
- Make the maxTimeout more accurate (count the time to open the first page / maybe count the captcha solve time?)
- Hide sensitive information in logs
- Reduce Docker image size
- Docker image for ARM architecture
- Install instructions for Windows
