💥 DosAttacker – Because Your Backend Deserves Some Cardio

⚠️ Disclaimer

This is a testing tool. It's built to stress-test your own infrastructure or stuff you’ve got explicit permission to slap with requests load test.

You definitely shouldn’t yeet it at production APIs you don’t own. We don't want to visit prison. Capisce? 😅

🚀 What Is This?

DosAttacker is a lightweight, multithreaded, no-nonsense HTTP spammer.
Just a bunch of Java threads and a beefy HttpClient doing reps.

You give it a list of endpoints. It goes full gorilla mode.

💡 Built for fun. Used to find out which of your microservices cries first.

🧪 Real Talk

When you hit your own backend with this thing:

• 💥 Some services fold faster than a cheap lawn chair
• 🧯 Some load balancers beg for mercy
• 🐢 Some APIs hit 504 like it's their day job

🚑 Confirmed fatalities during testing:

• Laravel APIs on shared hosting – fell over instantly
• Spring Boot apps on cheap VPS – lights out in 3 seconds
• Gosu servers (GuideWire) – don’t try. Same reason we don’t mess with bees: they’ve got stingers.

Great for testing scalability, timeouts, and how your ops team reacts under pressure.

🔧 Setup?

Come on. It's Java.

• JDK 17+ and you're golden.
• javac it. java it. Ship it.

No special sauce required. No Spring Boot bloat. Just raw, juicy threads and fire.

🛠️ Project Structure

DosStarter.java   -> Main launcher, spins up threads, prints stats
DosThread.java    -> One job: hit that endpoint until it dies or you do
DosStat.java      -> Just your local bean counter. Keeps score.

⚙️ Default Config

• Threads: CPU cores x 4 (you can change that if you're brave)
• Timeout: 500ms
• User-Agent: "Mozilla/5.0 TestBot" – we’re classy like that
• Jitter: Adds random delay so we don’t look too much like a bot (even though we totally are)

💡 Pro Tips

• Want to break things faster? Crank up the thread count.
• Want to be evil smart? Randomize headers or rotate params.
• Want to not get fired? Test on a local/staging env.
