Social media decision
Monk
A limited self-hosted replacement for Monk’s core workflow (daily ad scraping + LLM-driven ad variants + a review UI) is realistic for a capable technical user, but you’d lose Monk’s onboarding, weekly creative review, continuous niche dataset and product polish.

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
- Continuously scrape public Meta ads in a niche, store and rank winners, then generate on‑brand ad creatives/text using an LLM and surface them in a review dashboard.
What it still won’t have
- Done-for-you onboarding and 1:1 setup calls
- Weekly creative review calls and human tuning from Monk team
- Monk’s pre-built dataset/continuous niche scanning and historical index
- Built-in credits and integration with the Monk generation engine and UI polish
What remains hard
- Product polish and ongoing maintenance

Runnable build prompt
Build a self-hosted ad-intelligence and generation service using Next.js (dashboard), Postgres (data), a background worker (Celery/RQ) for scheduled scrapes, and Docker for deployment. Core features in scope: (1) OAuth/setup UI to record a brand website and a Meta Page ID and accept a read-only Meta System User token; (2) a scheduler that scrapes and stores public Meta ads daily and records reach/engagement; (3) ranking logic for winners and simple filters (by reach, recency); (4) an LLM integration module (configurable to Higgsfield or OpenAI) that accepts a Brand Kit (logo, tone, sample lines) and generates N ad variants per winner; (5) a review page to preview generated statics/text, request revisions, and export assets; (6) Stripe billing stub for a single flat plan and team invite for up to 3 members. Out of scope: built-in image generation credits marketplace, paid onboarding calls, and native integrations to third-party image tools. Require error handling for API failures, retries for background jobs, unit tests for scraping/parsing and generation modules, and end-to-end tests for the dashboard flows.

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.
