Spin It
A small single-page random wheel spinner is realistic for one technical user to build and maintain; no durable moats were evident in the supplied page.

Open-source builds that already do this
Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All Spin It alternatives, with the arithmetic →
What a replacement has to do
- User supplies options → render interactive wheel → animate spin and pick random segment → display and optionally share/save result
What it still won’t have
- Polished UI/branding and marketing
- Hosted uptime and global CDN delivery
- Built-in analytics and usage tracking
- Pre-made integrations or account management
What remains hard
- Product polish and ongoing maintenance
First-year cost
No published price
Spin It does not publish a price we could read, so there is nothing to compare against. What building costs is below.

Runnable build prompt
Build a single-page wheel spinner app using React, TypeScript, and SVG (or Canvas) served from a static host (Vercel or Netlify). Core features in scope: option list editor (add/remove/reorder), SVG wheel renderer that maps options to colored segments, deterministic random selection with an option for uniform or recency-biased weighting, smooth spin animation that lands reliably on the chosen segment, and generation of a shareable URL encoding the option list. Out of scope: user accounts, payments, analytics dashboard. Include error handling for malformed input, unit tests for the selection algorithm, and end-to-end test of the spin flow. Provide Dockerfile for local dev and a short deploy script for Netlify/Vercel.
How we checked
How the score was reached
- Build verdict base78
- An open-source build was found+5
- 2 cited sources+1
- 3/3 assessment runs agreed+4
- Evidence score88
The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
