Image and video decision
PassiveShorts
A single competent developer can build and operate a useful MVP replacement (script -> images -> TTS -> FFmpeg -> auto-post) within a week and modest monthly API/hosting costs; nothing on the product pages claims an unreproducible 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 PassiveShorts alternatives, with the arithmetic →
What a replacement has to do
- Choose a topic -> generate a short script -> generate an image per script line -> generate lifelike TTS -> assemble images+audio+captions into a short video -> schedule and auto-post to TikTok/YouTube
What it still won’t have
- Polished multi-style UI and dozens of ready-made visual themes
- A maintained library of curated voices and preset caption animations
- Commercial-grade reliability, scaling, and cross-account support
- The vendor's 7-day money-back, billing UX and affiliate program
What remains hard
- Product polish and ongoing maintenance

Runnable build prompt
Build a minimal faceless short-video autoposter as a web app using React (dashboard) + FastAPI (backend) + Postgres (metadata) + Redis (task queue) + Celery + FFmpeg for media assembly. Integrate OpenAI-compatible LLM for script generation, a public image-generation API (e.g. Stability or Replicate) for per-line images, and an ElevenLabs-compatible TTS API for voice. Implement: user auth, create/manage 'series' (topic, visual style, voice), script generation, image generation per script line, TTS generation, timed captions with word timings, FFmpeg pipeline that produces a vertical short, task scheduling for posting cadence, OAuth-based connect and publish to YouTube and TikTok, web UI to review drafts and mark public/private, and basic billing-record placeholders. Out of scope: advanced multi-style theme editor, commercial multi-tenant billing, affiliate program, and analytics dashboard. Include error handling, retries for external API calls, unit tests for core pipeline steps, and an integration test that runs end-to-end generating a single video.

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.
