PromptBase

Marketplace for buying and selling prompts, mostly for image models.

PromptBase sells individual prompts, most of them producing a specific visual style in Midjourney or similar models. You are paying for someone else's trial and error rather than for software.

A marketplace for prompts only makes sense if prompts are scarce, and they are steadily becoming less so — models need less coaxing than they did, and good prompts get shared freely within hours. The case that survives is narrow: a specific, tuned prompt for a specific model that saves you an afternoon of iteration. Check the model version a listing targets before buying, because a prompt tuned for a superseded model is the most common way to waste money here.

Our take

A marketplace for buying and selling prompts. Whether that makes sense depends entirely on how durable the prompt is — a prompt is a piece of text that any buyer can read, copy and adapt, and the underlying model changes underneath it. The listings that hold value are those bundled with real workflow knowledge rather than a clever phrasing.
