OpenBullet 2 is a powerful, open-source automation and web-testing suite used primarily for scraping data, API testing, and automated penetration testing. Rebuilt from the ground up to succeed the original OpenBullet, it offers a more flexible web-based interface and cross-platform compatibility. Key Features
Cross-Platform Support: Unlike the original version, OpenBullet 2 can run on Windows, Linux, and macOS using .NET Core.
Multi-Threading: Utilizes asynchronous methods to execute parallel requests, significantly increasing data collection speed.
Web-Based Interface: Features a modern, user-friendly dashboard accessible through any web browser (defaulting to http://localhost:5000).
Flexible Configs: Heart of the tool, "configs" are text files that instruct the program on how to navigate specific websites, solve CAPTCHAs, and parse data.
LiteDB Integration: Uses a lightweight NoSQL database (LiteDB) to store proxies, wordlists, and results. Setup & Installation openbullet 2
OpenBullet 2 (OB2) is a web testing suite that allows users to perform requests towards a target web app and offers a lot of tools to work with the data. It is a complete rewrite of the original OpenBullet, designed to be cross-platform (running on Windows, Linux, and macOS) using the ASP.NET Core framework. ⚙️ Core Architecture and Functionality
OpenBullet 2 operates as a flexible scraper and API testing tool. Its core is built around "Configurations" (configs), which are sets of scripts and parameters that tell a bot how to interact with a specific website.
LoliCode: OB2 uses a custom scripting language called LoliCode, which allows for complex logic, statements, and blocks to control the flow of a script.
Blocks: These are modular units of code (e.g., HTTP Request, Parsing, Scripting) that can be stacked to build a configuration.
Cross-Platform: Unlike the original WinForms version, OB2 can be hosted as a web application or run as a native desktop client. 📝 Working with Long Text and Data OpenBullet 2 is a powerful, open-source automation and
Users often encounter challenges when dealing with "long text" or large data sets within the application.
[BUG] Debugger Log hangs with big sources · Issue #406 - GitHub
OpenBullet 2 is an open-source, cross-platform web testing suite written in .NET 6 (or later). It is the direct successor to the original OpenBullet, rebuilt from the ground up to address performance bottlenecks, add modern features, and improve user experience.
At its core, OpenBullet 2 is an automation tool designed to send massive volumes of HTTP requests to web servers and analyze the responses. It allows users to create "configs" (configurations) that tell the software what to send, where to send it, and how to interpret the response to determine success or failure.
While the developers intended the tool for legitimate security auditing (e.g., testing rate limits, brute force protections, and login flows), its incredible efficiency has made it the standard-issue weapon for credential stuffing attacks. Authorization : It is crucial that users of
OpenBullet 2 is an open-source, customizable, and modular tool designed for performing various types of network and system tests. It is essentially a network testing framework that allows users to create, manage, and execute tests against networked systems. This tool is often utilized by penetration testers, security researchers, and network administrators to assess the security and performance of networks and systems.
Authorization: It is crucial that users of OpenBullet 2 have explicit permission to test the systems they target. Unauthorized testing can lead to legal consequences.
Data Protection: Users must ensure that any data collected during tests is handled responsibly and in compliance with relevant data protection laws.
Understanding the black-hat workflow helps defenders build better countermeasures.
OpenBullet 2 is a complete rewrite of the original OpenBullet framework. At its core, it is a network testing tool designed to perform brute-force attacks, credential stuffing, and web scraping against HTTP/HTTPS-based applications.
Originally developed in C# (.NET Framework) for Windows, OpenBullet 2 is built on modern .NET 6/7/8, making it cross-platform (Windows, Linux, macOS). The interface has evolved from WinForms to a sleek Blazor-based UI (often run via a local server in a browser), offering better speed, stability, and configuration management.
