This is a submission for the DEV April Fools Challenge
What I Built
I built Anti-Debugger, a completely useless tool where you paste an error message and get confidently terrible debugging advice.
It is designed to feel just helpful enough for one second before becoming obviously dangerous.
Some of the advice it gives includes things like:
- “Turn your monitor upside down. The stack trace makes more sense that way.”
- “Set
allow read, write: if banana;and let destiny decide.” - “Your plugin was found spiritually, just not by Gradle.”
- “The stack trace is fine. You are the one who needs debugging.”
So yes, this proudly solves zero real-world problems.
Demo
Live demo: Anti-Debugger
You can try pasting:
- a React Native error
- a Gradle build failure
- a Firebase permission error
- a random stack trace
- or complete nonsense
The tool detects broad categories like React Native, Gradle, Firebase, or network issues, then returns themed terrible advice, along with a fake diagnosis, fake severity, and fake confidence score.

How I Built It
I first prototyped the idea with AI-assisted tools to move quickly on the concept, layout, and tone. I used Lovable and ChatGPT to shape the joke, the interface direction, and the absurd response ideas.
That part worked well for ideation, but I hit a wall when trying to publish directly from the builder, so I rebuilt the final version as a tiny static site using:
- HTML
- CSS
- JavaScript
The final app uses simple keyword-based category matching. If the pasted error looks related to things like Gradle, React Native, Firebase, or network failures, it picks from a matching pool of terrible advice. If not, it falls back to generic nonsense.
That made it lightweight, fast, and honestly more in the spirit of the joke.
Prize Category
I’m not specifically targeting a bonus prize category, but this project did use AI during the ideation and prototyping phase through Lovable and ChatGPT.
Anything Else?
This project was fun because it turns a very familiar developer experience — staring at errors and trying random fixes — into something intentionally unhelpful.
It is probably the only debugging tool I’ve made where making things worse was the whole point.

The line 'The stack trace is fine. You are the one who needs debugging.' is genuinely the most accurate diagnosis most of us have ever received. I pasted a real Gradle error and the confidence score was 94% — which is higher than any answer I've gotten from Stack Overflow. This is either the worst debugging tool or the most honest one. I can't decide anymore.
That’s a great review for this kind of project 😄
If Anti-Debugger starts sounding more believable than real debugging advice, that’s probably a bad sign.
"The stack trace is fine. You are the one who needs debugging." — I felt that one personally. The fake confidence score is the perfect touch. Every production incident deserves a tool that tells you the severity is CRITICAL but the diagnosis is "Mercury is in retrograde."
Glad that line landed 😄
“Severity: CRITICAL. Diagnosis: Mercury is in retrograde.” would fit the tool very well.
