robuster

Blazingly fast directory/DNS/vhost buster written in Rust 🦀

A high-performance alternative to gobuster, leveraging Rust's async runtime for maximum speed.

Features

• Blazingly Fast - Async I/O with tokio, connection pooling, zero-copy optimizations
• 7 Modes - dir, dns, vhost, fuzz, s3, gcs, tftp
• TLS Support - Full TLS/SSL support via rustls (no OpenSSL required)
• Proxy Support - HTTP and SOCKS5 proxy support
• Beautiful Output - Colored output with progress bar
• File Output - Text and JSON output formats

Installation

Build from source

git clone https://github.com/rohit/robuster
cd robuster
cargo build --release
./target/release/robuster --help

Usage

Directory Enumeration (dir)

# Basic usage
robuster dir -u https://example.com -w wordlist.txt

# With extensions
robuster dir -u https://example.com -w wordlist.txt -x php,html,js

# Show response length, follow redirects
robuster dir -u https://example.com -w wordlist.txt -l -r

# With custom headers and cookies
robuster dir -u https://example.com -w wordlist.txt -H "Authorization: Bearer token" -c "session=abc"

# High thread count for speed
robuster dir -u https://example.com -w wordlist.txt -t 50

DNS Subdomain Enumeration (dns)

# Basic usage
robuster dns -d example.com -w subdomains.txt

# Show IPs and CNAMEs
robuster dns -d example.com -w subdomains.txt -i -c

# Custom DNS resolver
robuster dns -d example.com -w subdomains.txt -r 8.8.8.8

Virtual Host Discovery (vhost)

# Basic usage
robuster vhost -u https://10.10.10.10 -w vhosts.txt

# Append domain to wordlist entries
robuster vhost -u https://10.10.10.10 -w vhosts.txt --append-domain --domain example.com

Fuzzing (fuzz)

# URL parameter fuzzing
robuster fuzz -u "https://example.com?id=FUZZ" -w payloads.txt

# POST data fuzzing
robuster fuzz -u https://example.com/login -w passwords.txt -d "user=admin&pass=FUZZ" --method POST

# Header fuzzing
robuster fuzz -u https://example.com -w tokens.txt -H "X-API-Key: FUZZ"

S3 Bucket Enumeration (s3)

robuster s3 -w bucket-names.txt

GCS Bucket Enumeration (gcs)

robuster gcs -w bucket-names.txt

TFTP Enumeration (tftp)

robuster tftp -s 10.10.10.10 -w filenames.txt

Global Options

Option	Description
-w, --wordlist	Path to wordlist file
-t, --threads	Concurrent threads (default: 10)
-o, --output	Output file (supports .json)
-q, --quiet	Suppress banner
-v, --verbose	Show errors
-z, --no-progress	Disable progress bar
--delay	Delay between requests (ms)

Performance

robuster is designed to exceed gobuster's performance through:

• Tokio async runtime - Non-blocking concurrent I/O
• Connection pooling - Reuses HTTP connections
• Streaming wordlist - Memory efficient for large files
• Release optimizations - LTO, codegen-units=1, stripped binary
