Betterprompt
A prompt marketplace billed per run — the credit cost is on the card before you click
Overview
A marketplace that sells prompts without handing them over: pick one, fill in a few blanks, choose a model (OpenAI, Claude, Gemini, Grok are all listed) and get a result in seconds. You pay per run, not per prompt — every run spends credits, and the card shows the cost up front, so nobody has to buy a prompt they haven't tried. Prompts execute on Betterprompt's own servers: buyers submit inputs and get outputs, never the prompt itself, which is exactly why creators are willing to list their best work. The split is stated in the FAQ — a run costs the model price plus a 10% platform fee and 10% to the creator, and failed runs refund the credits. There's also an agent-skill marketplace built on the same idea: the SKILL.md is open to read, the generation logic stays server-side.
Why it stands out
- Pay per run, no upfront purchase: their words are "No $5 upfront for a prompt you haven't tried" — credits are spent per run and refunded when a run fails
- The price is explained: model cost + 10% platform fee + 10% creator royalty, estimated from recent real runs on that model
- The prompt stays a black box — it runs on Betterprompt's servers, so users only ever see input and output. Bringing your own API key isn't allowed either ("Every prompt runs on our keys"): they'd rather lose those users than leak a creator's prompt
- Creators get paid through Stripe: publish once, earn on every run, with a dashboard for revenue, usage and reviews; payouts unlock at $10
- Agents install one master skill — npx skills add https://github.com/betterpromptme/skills --skill betterprompt — and use it to search and run skills in the marketplace, each with a readable SKILL.md and the generation logic kept separate
- Your inputs never train any model (theirs or their providers'); team features are still in private beta behind teams@betterprompt.me
People who want to sell the prompts they already wrote as an income stream, and people who'd rather fill in two blanks than learn prompt writing at all.
