Design and diagrams decision
Tattoo AI
A single developer can build and run a constrained replacement (prompt→image→download with quotas and Stripe billing) in about a week; the vendor's value appears to be convenience, pricing tiers, and support rather than an unreproducible moat.

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
- Describe tattoo → send prompt + optional reference image to an image-generation API → receive generated images → present gallery and allow download; enforce per-account quotas.
What it still won’t have
- Priority / VIP 24/7 support and guaranteed SLA
- Advanced studio profile features and multi-user studio management
- Built-in advanced API access and custom integration support
- Any proprietary model optimizations or undisclosed training data
What remains hard
- Product polish and ongoing maintenance

Runnable build prompt
Build a minimal AI tattoo-generation web app using Next.js (React) frontend, Node.js/Express backend, PostgreSQL for metadata, and S3-compatible object storage. Use Stripe for subscription management (one-seat plans) and webhooks to update per-account monthly quotas. Use a hosted image-generation API (e.g., Replicate or similar) to convert text prompts and optional reference image uploads into PNG outputs. Core features in scope: user sign-up/login (email), prompt + reference image upload, request generation to image API with progress/error handling, store results and metadata, enforce monthly quota per account, Stripe subscription checkout and webhook handling, frontend gallery with download, and automated tests for API endpoints and payment webhook flows. Out of scope: advanced studio profiles, team collaboration, custom enterprise integrations, AI model training. Include robust error handling, retries for API calls, logging, and unit/integration tests. Provide a README with deployment steps and required environment variables.

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.
