Appshots
A single competent developer can build a usable replacement in about one week and maintain it cheaply; Appshots' value appears to be templates, polish, and hosted convenience rather than an unreplicable moat.

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 Appshots alternatives, with the arithmetic →
What a replacement has to do
- User uploads raw app screens → select visual style/template → automated layout + headline placement across panels → render framed, export-ready images for target store sizes → download/export assets
What it still won’t have
- Polished, curated visual templates and headline layouts tuned for conversion
- Hosted credit/usage management and turnkey billing
- Vendor support and product polish (QA, cross-device testing)
- Any proprietary ML models or internal production optimizations the vendor uses
What remains hard
- Product polish and ongoing maintenance

Runnable build prompt
Build a minimal App Store screenshot generator as a hosted web app using Next.js (React) for frontend, Node.js/Express for backend, and Sharp (or Pillow via a Python microservice) for image processing. Core features in scope: (1) authenticated single-user flow, (2) multi-file upload and validation, (3) selectable visual templates/styles, (4) automated multi-panel layout engine that places headline text and spacing consistently, (5) compositing device frames and exporting store-specific asset sizes, and (6) ZIP download and simple credit usage counter. Out of scope: advanced AI-generated headline writing, multi-seat team billing, analytics dashboard, and a marketplace of templates. Include error handling for invalid uploads, concurrency-safe exports, unit tests for layout logic, and end-to-end tests for upload→export flow. Document deployment steps for Vercel (frontend) and a small Node.js worker on a single t3.small equivalent, plus an estimated monthly cost breakdown and automated backups for exported assets.

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.
