Bug Bounty Tools (2026)

The web hacking stack, explained

Quick answer

The basic bug bounty stack in 2026 is free: a proxy (Burp Suite Community or Caido), a fuzzer (ffuf + SecLists), recon (subfinder + httpx) and a scanner (nuclei). For exploitation, sqlmap and callback servers for blind bugs. Here's what each one is for and how they fit together.

Bug bounty tools 2026: the full stack, step by step

Proxy & interception

The heart of web hacking: intercept, modify and replay HTTP requests.

Burp SuiteGuide →

The reference proxy. Intercept traffic, replay requests (Repeater), fuzz (Intruder) and extend it via the BApp Store. Community is free; Pro adds the active scanner.

Caido

A modern Burp alternative written in Rust: fast, lightweight and with a clean workflow. Gaining traction among hunters in 2026.

OWASP ZAP

OWASP's open-source proxy. A solid free option to start intercepting and scanning at no cost.

Reconnaissance (recon)

Before attacking, map the surface: subdomains, live hosts, historical URLs.

subfinder

Blazing-fast passive subdomain enumeration using dozens of sources. The first step of almost any recon.

amass

Deep attack-surface mapping (subdomains, ASN, DNS). More thorough and slower than subfinder; they complement each other.

httpx

Probes which hosts are alive, with what technology and status code. Filters thousands of subdomains down to the ones worth looking at.

waybackurls / gau

Pull historical URLs from the Wayback Machine and other sources: old parameters, forgotten endpoints and juicy paths.

Shodan / Censys

Search engines for devices and services exposed on the internet. Useful for finding off-radar assets within scope.

Fuzzing & content discovery

Discover hidden paths, parameters and files with smart brute forcing.

ffufGuide →

Ultra-fast web fuzzer in Go: directories, VHOST, GET/POST parameters. Filters by code, size and words to separate signal from noise.

gobuster / dirsearch

Directory and file brute forcing. Classic and simple; great for uncovering forgotten panels and backups.

SecLists

Not a tool but THE collection of wordlists (paths, parameters, payloads). It's the fuel for every fuzzer above.

Scanning & automation

Automate the detection of known flaws and misconfigurations at scale.

Exploitation

Once you've found the flaw, these tools help you prove impact.

sqlmapGuide →

Automates the detection and exploitation of SQL injection: database dumps, file reads and even RCE on some engines.

Burp Collaborator / interactsh

Callback servers to detect blind vulnerabilities (Blind XSS, SSRF, OOB SQLi) that give no direct response.

XSS Hunter

A callback platform for Blind XSS: it alerts you when your payload fires in a private panel you can't see.

Frequently asked questions

What tools do I need to start in bug bounty?

You start with very little: a proxy (Burp Suite Community or Caido), a fuzzer (ffuf) with the SecLists wordlists, and some recon (subfinder + httpx). All of that is free. As you progress you'll add nuclei to automate, sqlmap for SQL injection and callback servers for blind bugs.

Burp Suite or Caido?

Burp Suite is the industry standard, with more extensions and documentation; its Community edition is free and enough to start. Caido is a modern Rust alternative, faster and lighter, that many hunters are adopting in 2026. Try both and keep the workflow you're most comfortable with.

Are these tools legal?

The tools themselves are legal: they're the same ones security teams use. What matters is where you use them. You should only point them at systems that authorize you: a bug bounty program within its scope, a contracted pentest, or labs and environments built for practice like BBLabs'.

Do I need to pay for bug bounty tools?

No. Most of the stack is open source and free (ffuf, nuclei, subfinder, sqlmap, ZAP, SecLists). Burp Suite has a free Community version; only its Pro edition is paid. You can do serious bug bounty with 100% free tools.

The tools are free. The hard part is knowing how to use them.

Practice with labs based on real reports: use Burp, ffuf and sqlmap against bugs that actually paid out, with a step-by-step writeup. Create your free account and start with the Academy.
