About

We make the tools fight. You keep the loot.

Stack Runoff is a small, automation-heavy test lab for indie game devs and vibecoders. Every month we pick a category, write a fair prompt set, and make the AI tools go head to head.

the arena

Same prompt in. Every output out. Placeholder art.

What we're about

✓

Receipts over vibes

Every claim on this site comes with the output, the prompt and the price we paid.

32

Indie-sized tests

Sprites at 32x32, a coin sound under a second, a jam page that actually loads. The stuff small teams really ship.

$

Your wallet's side

The headline number is always what one usable asset costs you, not a vibe score.

How we talk

Who's behind it

Stack Runoff publishes as a brand. Tests are run by a small, mostly automated crew with a human in the loop. We don't do influencer faces; the outputs are the star.
