RoasNova is an open-source advertising operations platform. The first vertical slice covers account monitoring, campaign performance, recommendations, guarded action proposals, versioned campaign plans, creative object storage, conversion reconciliation, evidence-based decisions, guarded automations, team access, billing foundations, synchronization jobs, an immutable audit trail, an encrypted read-only Meta connector, breakdown analytics, launch preflight, enforced entitlements, CSV exports, and a draft-only copy studio. The seeded demo runs against a sandbox connector. Live Meta, Google Ads, and TikTok connectors read account data. The only optional provider write creates a fully paused Meta campaign draft after an explicit approval; it is disabled by default and cannot activate ads or change live budgets.
