AltoRank

AltoRank is open-source SEO content software that checks whether search engines and AI assistants can read your site, researches what your buyers search for, and drafts articles in your site's voice with sources attached.

Every publish is attributed to a named person: a click on that draft, or a rule they set that emails each draft and ships it after a 24-hour hold unless they hold it. Drafts export as Markdown or HTML; CMS connectors are set up with you rather than self-serve today.

The whole product is open source under AGPL-3.0, with no feature held back. Self-host it free, or use the hosted version: €69/month, or €199/month on the Agency plan for unlimited client workspaces. Hosted plans include a 7-day trial. There is also an MCP server, listed in the official MCP registry as co.altorank/altorank, and a CLI.
