Automation and integrations decision
Missinglettr
A minimal Missinglettr replacement (content extraction → LLM post generation → scheduled posting + basic analytics) is reproducible by a capable developer over several weeks using existing open-source examples and LLM APIs; enterprise features and polish would be costly to match.

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.
What a replacement has to do
- User provides a content URL -> system extracts content and images -> generate multiple platform-specific social posts (templates, captions, images) -> schedule posts to social APIs and run drip campaigns -> collect basic posting analytics
What it still won’t have
- Proprietary influencer-discovery and niche-finding signals
- Built-in stock image library and licensing
- Enterprise support, whitelabeling, and advanced analytics
- Breadth of native integrations and polished scheduling UX
What remains hard
- Product polish and ongoing maintenance

What we assumed
The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a multi-tenant web app (Next.js frontend, FastAPI backend) that converts a blog URL into a scheduled social drip campaign. In scope: (1) HTML fetch + extract article text and images, (2) LLM-driven generation of 5 platform-specific post variants per article (call OpenAI/GPT or equivalent), (3) store campaigns and scheduled items in Postgres, (4) background scheduler using Redis + RQ or Celery to post via social APIs (Twitter/X, Facebook Pages, LinkedIn) with retries and webhooks, (5) lightweight React UI to review/approve posts and calendar view, (6) short link tracking via Bitly or self-hosted shortener, (7) basic analytics dashboard (post status, clicks). Out of scope: enterprise whitelabeling, influencer discovery engine, built-in stock image licensing, Instagram direct posting requiring mobile scraping. Include proper error handling, API rate-limit backoff, secrets management, automated tests for extraction/generation/scheduling flows, Docker deployment manifests, and a README with setup and run instructions.

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.
