PromptBase
Marketplace for buying, selling, and running prompts across the major image and text models.
Pick PromptBase if you ship image or copy work daily and want a cheap shortcut to a working prompt instead of iterating from scratch.
Skip it if you enjoy crafting your own prompts, need an API, or already have a strong internal prompt library.
PromptBase is a marketplace where prompt engineers list tested prompts for Midjourney, ChatGPT, DALL-E, FLUX, Stable Diffusion, Claude, Gemini, Leonardo and 40+ other models, and where buyers grab them for a few dollars instead of grinding the prompt themselves. The catalog runs past 270,000 prompts with previews, example outputs, and per-model filtering, plus a Hire section for commissioning custom prompts and a Create tool for wrapping prompts into mini apps.
Pricing for individual prompts typically sits between $2.99 and $9.99 a pop, with a PromptBase Select subscription from $19/month that bundles access to a curated 200k+ subset. It's aimed at people who treat prompts as production assets - marketers, indie image generators, agencies, ChatGPT power users - rather than researchers who enjoy crafting their own. Sellers get a built-in storefront and payout pipeline, which is the main reason the supply side stays this large.
Caveats: PromptBase isn't a model or an inference platform, there's no public API, and prompt quality is uneven - you're trusting the seller's screenshots and ratings. It's also a moving target as base models change, so older prompts can drift out of date.
PromptBase is the most established prompt marketplace and the supply side has stayed healthy through every model generation since GPT-3. Treat it as a time-saver, not a moat - the value is in the curation and previews, because the prompts themselves can usually be reverse-engineered with effort. Worth a few dollars; rarely worth a subscription unless you're a heavy Midjourney user.
