OpenBullet 2 Plugins

OpenBullet 2 is a flexible, user-driven tool used for web testing, scraping, and automating HTTP workflows. Plugins extend its capabilities by adding integrations, new input/output formats, custom modules, or helpers that simplify workflows and enable additional use cases. Below is a concise, structured guide covering what OpenBullet 2 plugins are, common types, how they’re developed and installed, best practices, and security/legal considerations.

3.4 Plugin Entry Point

using OpenBullet2.Core.Plugins;
public class CryptoPlugin : IPlugin
public string Name => "Crypto Tools";
public string Version => "1.0.0";
public string Author => "security_researcher";
public void Load(PluginContext context)
context.BlockFactory.RegisterBlock<HmacBlock>();
    context.LoliScriptFunctionRegistry.Register(new MathFunction());
    Console.WriteLine("[CryptoPlugin] Loaded successfully");
public void Unload()
// Cleanup logic

Step 1: Create a Class Library Project

dotnet new classlib -n MyCustomPlugin -f net8.0

Q4: My plugin is loaded but not working. Why?

• Check the Logs tab for errors (usually missing dependencies like Newtonsoft.Json).
• Ensure your API key is valid.
• Verify the plugin is compatible with your OB2 version (check release date).

The Future of Openbullet 2 Plugins

As of 2025-2026, the development of OB2 has slowed, but the community remains active. Trends include:

• AI-powered plugins that use local LLMs to solve text-based CAPTCHAs.
• Browser automation integration (Playwright instead of Selenium for speed).
• Blockchain logging (immutable hit records for legal audits).

The plugin architecture ensures that even if the core stops updating, the tool remains relevant through community extensions.

Why Use Plugins? Key Benefits

1. The "HitNotify" Suite (Discord/Telegram)

Most popular plugin type.

• What it does: Sends valid results (hits) instantly to a messaging platform.
• Why you need it: You don't have to watch the OB2 screen. As soon as a valid credential or data point is found, you get a rich embed notification on your phone or desktop.
• Examples: DiscordWebhook.dll, TelegramNotifier.dll.

The Ultimate Guide to OpenBullet 2 Plugins

OpenBullet 2 (OB2) is a powerful web testing suite. While the native block system (HTTP, Parse, Script) is robust, Plugins allow you to extend functionality beyond what is natively possible. They are essential for bypassing complex anti-bot measures (like Akamai or PerimeterX), decoding proprietary formats, or executing specialized algorithms.
