AltoRank

AltoRank is an SEO content engine for small teams and agencies. It finds the searches your buyers actually make, drafts articles against them, scores each one and checks every factual claim against a source, then publishes to the CMS you already use: WordPress, Shopify, WooCommerce, Webflow, Ghost, Framer, Wix, Notion, HubSpot or Magento.

It is approval-first: by default nothing publishes until a person approves it. It also checks, for free and without an account, whether ChatGPT, Claude and Perplexity can read your site at all.

The whole product is open source under AGPL-3.0 and free to self-host. Hosted plans start at €69 a month with a 7-day trial.
