A multilingual SEO workspace combining research, article generation, linking, and publishing.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Harbor is an AI-powered SEO content workspace for agencies, content creators, and in-house SEO teams. It combines competitor sitemap and content-gap research with keyword discovery, long-form SERP-grounded article generation, article refreshing, internal linking, imagery, topical authority clustering, and CMS publishing. Its multilingual workflow supports content in 52 languages, while team workspaces, brand voice profiles, a REST API, and an MCP server extend its fit for organized content operations.
The published plans show a freemium structure. Free costs €0 per month with monthly billing and includes 3 AI articles per month, 1 site, keyword and competitor research, and WordPress and Shopify publishing. Solo costs €24 per month with annual billing, raises output to 25 AI articles, adds unlimited sites, keyword and content-gap research, and automatic internal linking. Growth costs €39 per month with annual billing and adds 50 AI articles, unlimited research runs, bulk article generation, authority clusters, and Google Search Console. Powerhouse costs €82 per month with annual billing, includes 100 AI articles, and adds priority support alongside the bulk and clustering features.
Harbor’s main strength is breadth within an SEO content workflow: it can research competitors, generate and refresh articles, add links and visuals, cluster topics, track rankings through Google Search Console, and publish through connected platforms. Integrations include WordPress, Shopify, GitHub, Wix, Google Search Console, and Google Analytics, with web and API access. That makes it a strong fit for teams producing multilingual, research-led content across multiple sites. Buyers focused on a small volume of occasional articles may prefer the Free plan, while teams needing bulk generation, authority clusters, or Search Console tracking must move to Growth or Powerhouse. Organizations requiring priority support also need the highest tier.
