When to pick which

Pick FluxWriter if…

You want posts published on a schedule without touching an editor — Surfer scores content but never publishes it.
You want featured images, article schema, auto-indexing via GSC + IndexNow, and FAQ blocks per post at no extra step.
You publish to Shopify, Wix, or Webflow — Surfer has no CMS automation for any platform.
You want to start free and evaluate on real posts before paying — Surfer's Discovery plan starts at $49/mo with no free tier.

Pick Surfer SEO if…

You have writers who hand-craft every post and need a SERP-driven content score to optimize keyword density and structure.
You're auditing and updating an existing post archive rather than generating new articles at volume.
