Image and video decision
Sketchto
A capable developer can recreate a useful single-user image↔sketch converter using open-source diffusion tooling and a small web stack within a week and modest monthly inference costs; proprietary multi-model quality, credits UX, and scale are what you'd give up.

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 Sketchto alternatives, with the arithmetic →
What a replacement has to do
- Upload image/sketch → preprocess → call image-to-image model → return image and allow download → debit local credit counter
What it still won’t have
- Multiple proprietary professional models (Nano Banana Pro, Seedream, Flux Kontext) and their exact quality
- Large-scale cloud infra and low-latency multi-model hosting
- Built-in credit marketplace and packaged credit-packs billing UX
- Priority support, commercial licensing paperwork and SLA
What remains hard
- Product polish and ongoing maintenance

Runnable build prompt
Build a minimal image↔sketch web service in Node.js (Express) + React, store metadata in Postgres, and run model inference via a hosted inference API or a local diffusers-based server. In scope: file upload endpoint with validation (max 10MB, JPG/PNG/WEBP), image preprocessing (resize, normalize), an inference adapter that sends images to a hosted image-to-image/diffusion API and returns the result, a single-page UI for upload/preview/download, simple per-user credit accounting (one account, credit decrement per run), image history (thumbnails and timestamps), error handling, and unit + integration tests for upload, inference adapter, and credit logic. Out of scope: multi-model marketplace UI, payment integration beyond a stubbed billing call, advanced job queueing and autoscaling. Require proper input validation, rate limits, logging, and tests.

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.
