What you give up either way

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

An open-source project doing the core job proves a replacement is possible. It does not prove it matches Mirra, and it does not prove anyone has run it for a month. How we decide.
