Social media decision
Keryo
A competent developer can build a useful subset (idea → per-platform rewrite → schedule/publish + basic analytics) using open prior-art repos, but reproducing the full, polished multi-network, scale-ready SaaS with analytics and onboarding is multi-week and operationally heavier than a small self-hosted replacement.

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 Keryo alternatives, with the arithmetic →
What a replacement has to do
- User provides one idea → system generates platform-tuned variants using an LLM and client brand voice → schedule/publish via each platform's OAuth APIs → collect per-platform metrics and surface in a calendar/analytics UI.
What it still won’t have
- Polished, battle-tested UI/UX and UX polish for agency workflows
- Scale, reliability, and ops (retries, backfills, deliverability at volume)
- A/B tested per-platform prompt engineering and model tuning accumulated by vendor
- Integrated hosted analytics and historical attribution already wired to each platform
- Official MCP connector and bundled onboarding offered by vendor
What remains hard
- Product polish and ongoing maintenance

Runnable build prompt
Build a self-hostable social-media assistant in Node.js (Express) + React, Postgres for storage, Redis for scheduling, and deploy on a single small VPS (Docker). Core features in scope: OAuth2 connectors for X and LinkedIn (implement publish and token refresh), an LLM integration (OpenAI-compatible) that accepts one idea + a stored client brand voice and returns per-platform variants, a composer UI to edit generated variants, a scheduling engine that triggers publishes and retries on failure, per-client workspace model with AES-256 encrypted tokens, and a minimal analytics importer that fetches basic post metrics. Out of scope: every platform beyond X/LinkedIn, advanced analytics/attribution, multi-region scaling, and a polished commercial UI. Include error handling, token rotation, unit and integration tests for API endpoints, and Docker Compose for local dev and deployment.

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.
