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.
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.
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
- Plain words. "This tilesets badly" beats "suboptimal edge coherence".
- Kind to tools, honest about results. We roast outputs, not people.
- Numbers first, jokes second, never instead.
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.
