Getting Started
FluxWriter publishes to WordPress, Shopify, Wix, Webflow, Ghost, and any custom webhook endpoint (Pro and Agency). No plugin is needed to publish. WordPress uses the native REST API and Application Passwords, and Wix and Webflow use their standard public APIs with a token. Shopify is the one exception: you create a private custom app in your own Shopify admin to issue the Admin API token, which installs nothing on your storefront. On WordPress, a short PHP snippet lets the Yoast or Rank Math fields FluxWriter fills in save, and IndexNow needs a key file; each is added once. Most users are set up and publishing within minutes. A public REST API is available on the Pro and Agency plans, with full docs at /api-docs.
AI and Content
The Free trial writes with DeepSeek V3, Starter with Claude Haiku, and Pro and Agency choose Claude Haiku or Claude Sonnet per post; if the writing model fails, a backup model writes the post instead. AI featured images use Gemini once you switch them on (stock photos are the default). Posts run 800 to 3,000 words, set per post or schedule (300 to 1,500 through the REST API), and include a featured image, FAQ schema markup and SEO fields (Yoast or Rank Math on WordPress, the platform's own elsewhere), plus a table of contents once a post has three or more sections; Wix posts don't carry the schema or the table of contents yet. You can save a Generate Now post as a draft to review before going live (automatic schedules publish live unless the quality gate holds a post for review), write natively in dozens of languages, and bring your own Anthropic, OpenRouter and image-provider keys.
Plans, Billing, and SEO
- The Free plan is a 14-day trial with 5 posts and no credit card, scaling up to Agency for teams running up to 50 sites.
- Pay by card via Paddle or with crypto via Cryptomus; annual billing saves up to 20 percent.
- Subscription payments and Backlinks wallet deposits are final and non-refundable except where FluxWriter fails to deliver what you paid for, or where the law or our Terms of Service require a refund, so use the Free plan to evaluate first. Boost Domain Authority carries a DA 60 guarantee, credited back to your Backlinks wallet, and a permanently failed backlink order is restored to your Backlinks wallet.
- On every plan, once a WordPress site serves its IndexNow key file, every post fires an IndexNow ping to Bing, Yandex and other participants — Google does not accept IndexNow — and the Backlinks page lets you order high-authority backlinks to any published URL.
