404 FOUNDTHE TRAINX WEB HUNT

The web is hiding something

The web is hiding something.

Somewhere inside this website are broken interfaces, suspicious pixels, strange behaviours and things that probably should not exist.

Find what everyone else scrolls past.

Enter the huntHow this works

Inspect everything.

The DOM

What the browser built, which is rarely what the source implied.

The cascade

Why the rule you can see losing to the rule you cannot.

The network

Headers, status codes and the difference between them.

Storage

What the browser kept after you thought you had left.

Building websites teaches you how things should work. Debugging teaches you how they actually work.

By the end of a session you will have opened the Elements panel, the Styles pane, the Console, the Network tab, Application storage and responsive mode — because that was the only way to find anything.

Nothing above is part of the competition. The real ones are harder to find, and none of them are on this page.

404 FOUND / THE LOOP

Five things happen, over and over, until the clock runs out.

  1. 01

    ENTER

    A clock starts on the server. It does not pause because you closed the tab.

  2. 02

    INSPECT

    Open the panels you have never opened. The page is the evidence.

  3. 03

    DISCOVER

    Something behaves differently from what should logically happen.

  4. 04

    REPORT

    Where, what you expected, what happened, how to reproduce it.

  5. 05

    LEARN

    Root cause, the fix, and the interview question it came from.

First you learn to see what is broken. Then you learn to build what should exist instead.

THINK IT.TEST IT.BUILD IT.PITCH IT.

ONE ACCOUNT / TWO DIRECTIONS

Learn to see it. Then learn to make it.

404 FOUND

Find what's broken.

A deliberately strange website, a clock you cannot pause, and a report form that asks the questions a real bug report has to answer.

How the hunt works

PITCHX

Build what should exist.

A team, a problem worth solving, real students to test it on, something built, and ten minutes in front of a panel.

What PitchX is

Tutorials tell you
where to look.
We don't.

You will not be taught any of this. You will find it — by clicking things twice, resizing the window until something gives, and reading HTML you did not write.

404 FOUND teaches students to explore a system they did not build. PitchX teaches them to challenge an assumption they did not question. Both are the same instinct pointed at different problems, and neither is a course you can finish by watching.

Every verified discovery unlocks what you found, why it happened, how a developer would debug it, and the interview question the concept comes from.

You can keep scrolling.

Or start looking closer.

One university email. The clock does not start until you press the button.

Think it. Test it. Build it. Pitch it.

One account. Two ways to learn by doing. PitchX is an educational simulation — no real money, equity or investment is involved anywhere in it.
