OpenSEO
OpenSEO is a modern, open source SEO platform built for people and AI agents to work together on strategy, research, and content using real search data instead of generic advice. It brings keyword research, saved keywords, rank tracking, domain analysis, backlink research, technical site audits, AI visibility, and prompt exploration into one connected workspace. Users can expand seed topics into keyword ideas with search volume, difficulty, CPC, and intent signals, inspect live Google results beside those metrics, save promising opportunities, tag them for content planning, and monitor positions over time. Domain tools reveal estimated traffic, ranking keywords, top pages, backlinks, referring domains, and link quality, while site audits crawl pages for status codes, titles, meta descriptions, headings, indexability, image alt coverage, links, response times, and optional Lighthouse findings.
