Mirra
A capable technical user can build a useful, narrower Mirr replacement (generation + scheduling + basic automation) using existing open-source tools, but full parity (polished multi-channel integrations, brand-training history, enterprise features and analytics) requires substantial multi-week work and operational polish that Mirr already provides.

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 Mirra alternatives, with the arithmetic →
What a replacement has to do
- User provides brand/topic → system learns brand voice from past posts → generate multi-format content (carousel, post, blog, short video) → schedule/publish to connected social accounts → handle simple comment/DM automation → show performance metrics
What it still won’t have
- Polished, unified product UX with mobile-first approval flows and built-in design editor
- Proprietary brand-learning history and progressive personalization tuned by Mirr over many customers
- Pre-built, tested integrations and edge-case handling for each social platform
- Enterprise features (approval flows, SLA, legal review, multilingual operations) and any vendor support
- Precomputed ROI analytics tied to Mirr's internal events and dashboards
What remains hard
- Switching costs

Runnable build prompt
Build a self-hosted Mirr-lite: use Next.js for the frontend, Node.js (Express) for backend, Postgres for storage, Redis for queues, FFmpeg for video assembly, and OpenAI/compatible LLM API for text generation. Core features in scope: (1) OAuth publish integrations for Threads, X, Instagram, YouTube, TikTok, LinkedIn (connect one account per channel); (2) ingest and analyze past posts to build per-brand embeddings and a brand prompt template; (3) LLM orchestration to generate social posts, a 5-slide carousel (image+caption), and a short-video storyboard; (4) image/carousel renderer using HTML-to-image or headless Chromium and FFmpeg-based short-video assembler with TTS; (5) scheduler service to queue and publish posts with retries and webhook handling; (6) simple rules-based comment/DM auto-reply and escalation; (7) minimal analytics (impressions/engagement counters) and an approval UI. Out of scope: enterprise-grade SLA, multilingual pipelines beyond English, large-scale multi-tenant billing, advanced ROI attribution. Include error handling, logging, background job tests, and end-to-end tests for OAuth publish, generation, and scheduling 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.
