In the world of web testing, security auditing, and automation, few tools have gained as much notoriety and utility as OpenBullet. Originally released on GitHub, OpenBullet is an open-source .NET framework designed for stress-testing web applications. It allows security professionals to automate HTTP requests, test endpoint resilience, and audit login systems for weaknesses.
The version that remains the most discussed, requested, and widely used is OpenBullet 1.4.4. Despite being an older iteration, it is often considered the "gold standard" for stability, community support, and plugin availability.
However, before you search for "download openbullet 1.4.4", it is critical to understand that this tool is a double-edged sword. While legitimate security researchers use it for penetration testing, attackers abuse it for credential stuffing—testing stolen username/password pairs against websites.
Warning: Unauthorized use of OpenBullet against websites you do not own or do not have explicit permission to test is illegal in most jurisdictions (violating CFAA in the US, Computer Misuse Act in the UK, and similar laws globally). This article is for educational purposes only.
After download, right-click the ZIP → Properties → Digital Signatures. A legitimate build may not have a signature, but you can use PowerShell to get the hash:
Get-FileHash .\OpenBullet.1.4.4.zip -Algorithm SHA256
Compare this hash with known good values from official release notes.
Once you have the clean ZIP file, follow these steps:
OpenBullet.exe → Run as Administrator. This ensures proper proxy and TCP/IP handling.Data folder containing Settings.json, Proxies.txt, and Wordlists subfolders.If you see an error about missing DLLs (like Newtonsoft.Json.dll), download the .NET Framework runtime or re-extract the original ZIP.
This paper aims to provide a balanced view of OpenBullet 1.4.4, emphasizing both its utility and the responsibilities that come with its use. download openbullet 1.4.4
| Question | Answer | |----------|--------| | Can you download OpenBullet 1.4.4? | Yes, from mirrors/forks | | Is it safe? | Not from untrusted sources | | Is it legal to use? | Only on systems you own | | Will it get you banned from services? | Yes, if detected | | Should you use it for credential stuffing? | No – that is a crime |
If you found this write‑up while researching credential stuffing tools – stop and reconsider. Security testing requires permission. Use your skills ethically.

OpenBullet 1.4.4 is a legacy version of a popular open-source automated web testing application designed primarily for credential stuffing, data scraping, and API testing. It functions by executing user-defined "configs" (scripts) against target websites to check for valid logins or specific data points.
Important Notice: This tool is frequently associated with illegal activities like account takeover (ATO). Using it against sites without explicit permission is illegal. Download OpenBullet 1.4.4
While official repositories have moved to newer versions (or to SilverBullet), the legacy 1.4.4 version can be found in archived repositories.
Source/Archives: Look for OpenBullet.zip in GitHub archive repositories like openbullet/openbullet (released ~June 2020).
Requirements: Requires .NET Framework 4.7.2 or higher, as well as modern OS security libraries. In the world of web testing, security auditing,
Build Instructions: Clone the repo, open the solution in Visual Studio, and build in Release mode to generate the .exe files in the bin/Release folder. Write-up/Overview of OpenBullet 1.4.4
1. Purpose and FunctionalityOpenBullet 1.4.4 acts as a specialized HTTP client. It automates browser-like requests, allowing users to load lists of usernames/passwords (wordlists) and proxies to test thousands of requests per minute. 2. Core Components
Configs (.lolly / .anom): These are the core scripts that dictate how the bot interacts with a specific site’s login form.
Proxies: Essential for hiding the user's IP address and bypassing rate limits or geolocation restrictions. Wordlist: The database of user credentials to be tested.
Runner: The engine that manages concurrent requests, showing live hits (successful logins), fails, and errors. 3. Key Features in 1.4.4
LS (LollyScript): A domain-specific language used to create configurations. It allows for complex logic, including parsing, cookie management, and HTTP header manipulation.
Captcha Solving Integration: Supports external services for bypassing anti-bot measures.
Data Parsing: Uses block commands to extract specific HTML elements or JSON responses, such as account balances or subscription details. 4. Usage Lifecycle Import Proxies & Wordlist: Load proxies and credentials. After download, right-click the ZIP → Properties →
Select/Create Config: Select a pre-made config for the target website. Setup Runner: Define the speed (Bots) and start the test. Analyze Results: Review the "Hits" for valid credentials.
5. Evolution (1.4.4 vs Modern)While 1.4.4 is functional, newer iterations (like SilverBullet) improve performance and fix bugs. To help you better with this, I need to know:
Are you using this for educational security testing or web scraping?
Do you need help creating a config (.lolly file) for a specific, authorized target?
I can provide more detailed information on setting up the HTTP parser if I understand your goal.
