IronBullet

Visual pipeline builder for HTTP automation and data checking

---

IronBullet is a desktop automation toolkit built around a visual, drag-and-drop pipeline editor. Chain together 50+ specialized blocks — HTTP requests, parsers, crypto functions, browser automation, protocol clients — and run them against full datasets with multi-threaded job execution.

Features

Block pipeline editor	Drag-and-drop interface with 50+ block types across 8 categories
Debug mode	Step-through execution with live request/response viewer and variable inspector
Multi-threaded jobs	Configurable thread pools, proxy rotation, ban detection, gradual ramp-up
Intellisense	Context-aware autocomplete in all input fields — variables, headers, delimiters, response body predictions
TLS fingerprinting	AzureTLS, RustTLS, and WreqTLS backends with per-block JA3/HTTP2 fingerprint control
MITM capture	Built-in proxy captures browser traffic for Site Inspector — export as JSON/HAR
Code export	Export any pipeline as standalone Rust source code
Plugin system	Hot-loadable plugins extend the block palette without recompiling
OB2 import	Import OpenBullet 2 / SilverBullet configs (.svb, .opk, .loliScript)

Installation

Download the latest release for your platform:

Platform	File
Windows	ironbullet-vX.X.X-windows-x64.zip
Linux	ironbullet-vX.X.X-linux-x64.zip or .AppImage

Extract and run ironbullet (or ironbullet.exe). The sidecar binary (reqflow-sidecar / reqflow-sidecar.exe) must be in the same directory.

Linux users: The AppImage bundles all dependencies including WebKit. The .zip build requires webkit2gtk-4.1 to be installed.

Quick Start

1. Launch IronBullet
2. Add blocks from the left palette or press Ctrl+K
3. Click a block to open its settings in the right panel
4. Press F5 to run a debug test with a single data line
5. Open the Response Viewer to inspect HTTP traffic
6. Create a Job to process a full wordlist with multiple threads

Build from Source

Requirements: Rust 1.80+, Node.js 20+, Go 1.23+

git clone https://github.com/ZeraTS/ironbullet.git
cd ironbullet

# 1. Build the frontend
cd gui && npm install && npm run build && cd ..

# 2. Build the sidecar
cd sidecar && go build -o reqflow-sidecar && cd ..

# 3. Build the app
cargo build --release

The binary is at target/release/ironbullet. Copy it alongside reqflow-sidecar to run.

Cross-compile for Windows (from Linux):
