Why Scavio Wins
- n8n's value is composability + auditability. Each node is one transformation; per-step output is inspectable; the pipeline is portable across n8n cloud and self-hosted.
- Scavio fills the SERP/Reddit/YouTube research role with typed JSON the next node can consume directly. No HTML parsing, no Cloudflare fights inside the pipeline.
- Per-piece cost at $0.50-2 (Scavio research + LLM draft + fact-check) is predictable. Agency-scale economics: 50 pieces/mo × $1.50 = $75/mo data cost across all clients.
- Honest case for Frase: when you need content output today and don't want to build, Frase Solo at $44.99/mo gets you to first draft fast. Trade is per-seat scaling and lock-in.
- Auditability matters at agency scale. When a piece fails QA or a fact-check, you can inspect each step's output. Single-vendor platforms hide the steps; n8n exposes them.
