no slop survives.
a rapid app building league with automated stress testing
build with AI | defend it | pitch it
We took a hackathon and messed up the units. You have 24 hours minutes to build, and then everything you built gets put to the test.
hack•let(hæk-lət)n.
- An app built in a very short amount of time, typically with AI assistance: My roommate built a hacklet while waiting for his flight.
- A tightly compressed hackathon with an audience possibility: Come attend a hacklet; it lasts no longer than a cs club meeting.
# how it works
HackLet League runs two formats. Both compress engineering into 24 minutes with AI, both run the same QA catalog at time expiry, both score across slop and communication. They differ in what you do during the build phase.

you'd call "slop")## HackLet Vibe: build from scratch
Build a working web app with AI assistance of your own choice.
$ ./hacklet --format vibe --timeline 5 min opening · round prep 24 min build · ai-assisted building (aka vibecoding) 18 min defend · qa testing + pitch prep 5-30 min pitch · judging 8 min awards · closing
HackLet Vibe is akin to a traditional hackathon except with time compressed to minutes instead of hours. As AI is ubiquitous, HackLet Vibe tests if you can build apps of function, instead of apps of just form.
## HackLet Unslop: fix the slop (hence the name ;) )
Receive a broken AI-written codebase at the beginning. Figure out what’s wrong across multiple dimensions and improve upon it. Ship a defended version.
$ ./hacklet --format unslop --timeline 5 min opening · broken codebase revealed 24 min remediate · ai-assisted diagnosis and repair 18 min defend · same qa testing + pitch prep 5-30 min pitch · same judging 8 min awards · closing
HackLet Unslop reflects the reality of engineering work: working with existing codebases that may or may not be functioning ideally. HackLet Unslop tests if you can deal with existing code you see at work... under pressure.
# First HackLet coming soon
I’m still building this. Leave your email and I’ll let you know when there’s a HackLet to sign up for.
