ZloyProxy

ZloyProxy is a specialized proxy server for installation on your hardware (On-Premises). Its main task is spoofing low-level network fingerprints (TLS and HTTP/2) to bypass modern WAFs (Web Application Firewalls) and advanced anti-fraud systems.

This is a tool created for developers and automation specialists, allowing scripts and bots to be masked as legitimate traffic from real browsers.

What is ZloyProxy for?

Modern protection systems, such as Cloudflare, AWS WAF, and Akamai, have learned to block automated traffic not only by IP or behavior but also by the "digital fingerprint" of the connection itself. They analyze the TLS handshake (JA3/JA4 fingerprint) and HTTP/2 parameters (Akamai fingerprint) to determine what software is accessing them.

Problem: Your Python script (requests, httpx), ZennoPoster bot, or C#/Go software leaves a unique network fingerprint that instantly gives them away and leads to a block.

Solution: ZloyProxy acts as an intermediary that modifies these fingerprints on the fly, replacing them with fingerprints of real browsers (Chrome, Safari, Firefox) from its extensive database. As a result, for the WAF system, your bot becomes indistinguishable from a regular user.

From a client's review: "We just change them, leave everything else as is, and a miracle! Regs [registrations] go one after another."

Place in the Zl0yTeam Ecosystem

ZloyProxy is part of the overall product ecosystem and perfectly complements ZloyRouter.

  • ZloyRouter: Operates at the L3/L4 layers (network, transport). Its task is to build a "clean and armored tunnel" to the target, hiding the fact of VPN/proxy usage and protecting against DNS/UDP leaks.
  • ZloyProxy (this product): Operates at the L4-L7 layers (transport, application). Its task is to ensure that the "vehicle" (your software) driving through this tunnel is indistinguishable from a regular civilian one by spoofing TLS and HTTP/2 fingerprints.

For maximum anonymity and bypass capability, they are used in a bundle that covers practically all network detection vectors.

Key Technologies and Features

  • 🧬 TLS (JA3/JA4) and HTTP/2 Fingerprint Spoofing:
    The core feature. Masks your software as a legitimate browser. ZloyProxy uses a database of ~1500 real fingerprints collected from various devices and browser versions.

  • ⚙️ API for Automation:
    Allows dynamic changing of fingerprints and outgoing proxies "on the fly" via simple POST requests. Perfect for integration into complex automation workflows (mass registration, parsing) on ZennoPoster, BAS, Python, etc.

  • 🚀 Multi-threaded Version:
    Provides the ability to run multiple ZloyProxy instances on different ports with individual settings. This is necessary for scaling operations and working simultaneously with different configurations.

  • 🔒 Full Support for TLS 1.3 and WebSocket:
    Includes support for pre_shared_key and Session Ticket for proper operation with the most modern websites and web applications.

  • 🔌 Ease of Integration:
    To your software, ZloyProxy looks like a regular SOCKS5 or HTTP proxy. Integration comes down to specifying the ip:port address in the settings of your HTTP library (e.g., curl, requests).

  • ✅ Active Development and Support:
    The product is constantly updated to support new browser versions and TLS specifications. You get direct contact with the developer, who helps solve non-standard tasks and listens to feature requests (up to creating custom builds with the necessary functionality).

Who is this product for?

ZloyProxy is a professional tool for technically savvy specialists.

  • ✅ Automation Software Developers: Who write software in Python, GoLang, C# and encounter blocks from WAFs.
  • ✅ ZennoPoster, BAS, Private Keeper Specialists: Who need to scale their projects and bypass bot protection.

❌ Who is NOT our user:

  • Entry-level users using headless browsers (Selenium, Puppeteer, Playwright) or no-code/low-code platforms (n8n, Make). These tools have their own, higher-level detection methods, and ZloyProxy is not a "silver bullet" for them.

How it Works and Integration

The workflow scheme is extremely simple: your script sends requests not directly to the target website, but to the local ZloyProxy port.

Your software           ZloyProxy                     Target website
(Python, ZennoPoster)   (spoofs fingerprints)         (sees traffic from
     |                        |                         a browser)
     '------(proxy)--------->'------------(TLS)------------->'

Example of integration with curl:

# Just specify ZloyProxy as a regular proxy server
curl --proxy http://127.0.0.1:8080 https://tls.browserleaks.com/json

ZloyProxy will handle everything else itself.

Popular Scenario: ZennoPoster (Windows) + ZloyProxy (Linux)

Many automation tools run on Windows. ZloyProxy, however, runs on Linux. The ideal setup looks like this:
1. A virtual machine (e.g., VirtualBox or VMWare) with Ubuntu/Linux Mint OS is installed on your Windows computer.
2. ZloyProxy is launched on this virtual machine.
3. In ZennoPoster, you simply specify the network IP address of the virtual machine and the port (e.g., 192.168.1.127:8001).

Thus, ZloyProxy is completely isolated from your main system, but transparently works with all your tools.

How does ZloyProxy differ from libraries and alternatives?

Unlike open-source libraries (curl_cffi, noble-tls, pytls) and other solutions, ZloyProxy offers a different approach:

  • Ready-made server solution: You do not need to compile libraries for different OS, fight dependencies (OpenSSL, BoringSSL), or write wrappers. ZloyProxy is a ready-to-use binary file that simply runs and works stably.
  • Out-of-the-box multithreading: Makes it easy to scale the load, which is difficult to achieve with standalone libraries.
  • Management via API and web interface: Allows flexible configuration management on the fly without restarting scripts.
  • Unified fingerprint database and support: You get access to a constantly updated fingerprint database and professional technical support.

In simple terms, libraries are the "engine", and ZloyProxy is a "ready-to-drive car with a dashboard and maintenance service".

Use Cases

  • Automated account registration (auto-reg of emails, social networks, marketplaces).
  • Data parsing from websites protected by Cloudflare/Akamai.
  • Brute-force and credential checking.
  • Boosting behavioral factors and other SEO tasks.
  • Automated booking (tickets, hotels, limited goods).

Pricing and Licensing Model

  • Model: On-Premises Subscription.
  • ZloyProxy (multi-threaded version + API): $1100 / year.
  • 🎁 Bonus: Upon purchasing a ZloyProxy license, you receive a license for ZloyRouter as a gift.

Note: The single-threaded version is not popular and is available upon request. The main product is the multi-threaded version.

FAQ (Frequently Asked Questions)

Click to expand answers to frequently asked questions #### General questions and compatibility
Q: Will ZloyProxy work on Windows? A: No, ZloyProxy is designed to run on **Linux (Ubuntu is recommended)**. For Windows users, the ideal option is to run it on a separate Linux server (VPS) or on a local virtual machine (e.g., VirtualBox with Ubuntu) on the same PC where your software (ZennoPoster, BAS, etc.) is installed.
Q: How will my Windows software interact with ZloyProxy on the virtual machine? A: Very simply. ZloyProxy opens ports on the IP address of the virtual machine. Your software will access them via the network address, for example, `192.168.1.127:8001`, `192.168.1.127:8002`, etc.
Q: Is the TLS fingerprint transmitted only when visiting a site via a browser? A: No, the fingerprint is transmitted during **any** HTTPS connection, including `GET` and `POST` requests from your scripts. This is exactly the point of spoofing it.
#### Multithreading and API management
Q: How does the multi-threaded mode for changing fingerprints work? A: You launch ZloyProxy, which opens multiple ports (e.g., 100). Each port has its own unique fingerprint "attached" to it. In your software, you simply iterate through these ports in a loop so that each new thread goes with a new fingerprint.
Q: How can I use my external proxies in ZloyProxy (e.g., `socks5://login:pass@ip:port`)? A: ZloyProxy works in proxy-chaining mode: `Your software -> ZloyProxy -> Your external proxy -> Website`. An external proxy can be set either via the configuration `.tsv` file at startup or (more flexibly) changed "on the fly" for any port via the management API.
Q: Can I change the proxy or fingerprint for a running thread without restarting ZloyProxy? A: Yes! This is a key feature of the API version. You can send a POST request to the management port `8888`, specifying for which worker port the outgoing proxy or fingerprint needs to be changed.
#### Installation and common errors
Q: When launching, the error `Hash check - error code: 12` occurs. What should I do? A: This error means that the program cannot connect to the license server.
  • **Solution #1 (most common):** Disable the VPN on the server/virtual machine where ZloyProxy is running.
  • **Solution #2:** Check that your DNS servers are working correctly.
  • **Solution #3:** In rare cases, it may be necessary to write the IP of the license server in `/etc/hosts`. Contact support for the current IP.
Q: I see a `connection reset by peer` error. What is the problem? A: This means that the remote server (the website or your external proxy) has forcibly dropped the connection. A frequent cause is that your proxy provider itself blocks the traffic, or your ISP uses DPI to block traffic (relevant for the Russian Federation). The solution can be using `ZloyRouter` or any VPN to "wrap" all traffic into a tunnel.
