Proofpopify
A competent developer can build and run a small Stripe-backed social-proof widget replacement in about a week; the product's value is integration and convenience rather than defensible data or network effects.

No open-source build does this yet
Nothing published replaces this one, so a replacement starts from an empty file. Here is what it would have to cover.
What a replacement has to do
- Read recent Stripe charges, verify transactions, surface them through an embeddable client-side script, and provide a dashboard to customize widget appearance and settings.
What it still won’t have
- Priority Stripe Syncing (a paid feature listed on the product page)
- Hosted managed dashboard and support
- Remove Watermark option (available in paid plan)
- Built-in Stripe Verification Page and branded hosting/SLAs
What remains hard
- Product polish and ongoing maintenance

Runnable build prompt
Build a minimal ProofPopify replacement: use Node.js + Express for the backend, PostgreSQL for settings/events, and React for a tiny admin UI; host frontend and embed on Vercel and backend on Render or Vercel Serverless. Core features in scope: (1) Stripe Restricted key connection and server endpoint to fetch/verify recent charges; (2) store admin settings (themes, position, CTA) in Postgres; (3) lightweight embeddable JS (<10KB) that loads async, fetches verified events, and shows popups; (4) admin dashboard to connect Stripe and change appearance; (5) secure storage of only non-sensitive public metadata and a small cached event list. Out of scope: analytics dashboards, priority sync queues, watermark removal UI, multi-team billing. Include error handling for Stripe errors, input validation, unit tests for core endpoints, and deployment scripts for Vercel/Render.

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.
