Version, evaluate, and ship
prompts like code.
SpacePrompts is the prompt management platform for teams shipping with AI. Write prompts, run them in the Playground, version every change, and fetch the current version over HTTPS. Built for people who use AI every day, not note-takers.
No credit card. Free tier stays free.
The problem
Your prompts have problems you can't see.
The prompt that's been running in your app for three weeks is making decisions every minute. You haven't looked at it since the rewrite. The Enhancer reads any prompt and surfaces the specific things that weaken it: missing output structure, vague rules, no length constraint, undefined source criteria. Each one scored, with a fix.
Comparison
Notion, a git repo, or this.
Plenty of teams start with a doc. Plenty of engineers reach for a git repo. Both work, until they don't. Here's what each one does well and where it stops.
Notion / Docs
Where most teams start. Free, familiar, no learning curve.

The loop
Every prompt starts in the Playground.
Write from scratch, generate from a goal, or fork a template. Run it against any model, see what it does, save the version. From there it lives in version history, in a shared workspace, and behind an API call. One loop, five surfaces, no copy-paste.
Playground
Editor, variables, model picker, instant run. Where prompts begin.
Score and improve it
Run it in the Playground and score it with the Evaluator. See what is weak and fix it.
Every edit, kept
Every save is a version. Roll back when v13 turns out worse than v12.
Into a workspace
Your team sees it, can edit it, and leaves an audit trail behind.
Fetch over HTTPS
One API call pulls the current version into your app. No SDK required.

Frequently Asked Questions
Need help with something? Here are some of the most common questions we get.
Because you don't just use ChatGPT. You perfect a coding prompt in ChatGPT. Next week you need it in Claude. So you open ChatGPT, scroll through 50 conversations, copy it, switch to Claude, paste. Now you're tweaking it in Claude. Which version is better? No idea—they're in different apps. SpacePrompts gives you ONE library that works everywhere. Save once, use anywhere. With version control so you actually know what works.
Because you're optimizing for storage, not retrieval. When was the last time you actually found that perfect prompt from 3 months ago in under 10 seconds? SpacePrompts is built for speed, not organization theater.
