Image and video decision
BeGen
A focused web service that reproduces core photo-to-short-video features is realistic for a single technical person using open-source repos, but matching the mobile polish, multiple proprietary models, subscription/credits UX, and scale of the paid app is larger than a one-person short project.

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 BeGen alternatives, with the arithmetic →
What a replacement has to do
- Upload a photo or enter a prompt → run an AI pipeline to animate/generate a short vertical video → encode and deliver downloadable/shareable video.
What it still won’t have
- Mobile-native iOS app and App Store distribution
- Polished templates, UX, and iterative mobile optimizations
- Access to any proprietary/hosted models the vendor bundles
- Built-in credit/subscription management and analytics
- Scale and reliability of a production consumer service
What remains hard
- Product polish and ongoing maintenance

Runnable build prompt
Build a minimal web service (React frontend + Node/Express backend) and GPU-backed inference worker (Python) that lets a user upload a portrait photo or enter a text prompt and produce a short vertical (9:16) AI-animated video. Stack: React + Tailwind for UI, S3-compatible storage (DigitalOcean Spaces or AWS S3), Postgres for metadata, Redis queue (BullMQ) for jobs, Python inference code using LivePortrait and video-retalking repos plus FFmpeg/moviepy for encoding, deployed to a single GPU VM (e.g., AWS g4dn or equivalent) behind an Nginx reverse proxy. In scope: file upload, job queue, model inference wrapper, frame-to-video encoding, simple progress UI, downloadable MP4, error handling, logging, and unit tests for API endpoints and the inference wrapper. Out of scope: mobile native app, multi-tenant billing, analytics dashboard, advanced template library. Include retries, input validation, storage cleanup, and basic CI to run 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.
