What OpenSEO provides

Core capabilities listed on the public OpenSEO product.
  • Keyword research & saved keywords

    Find ideas with demand, difficulty, intent, and live SERPs; organize opportunities for content and tracking.

  • Domain overview & backlinks

    Estimate organic visibility, inspect referring domains, and review link quality for competitor research.

  • Rank tracking & site audit

    Monitor keyword positions over time and crawl pages for technical SEO signals.

  • AI visibility & Prompt Explorer

    Look up brand mentions in AI search and compare answers across supported models.

  • OpenSEO MCP & Search Console MCP

    Connect Claude, Codex, and other agents to SEO data and Search Console performance for agent-assisted workflows.

  • Open source & self-host

    Star the project on GitHub and self-host when you need to customize or keep more of the stack under your control.

How to use OpenSEO

A practical research-to-agent workflow.
  1. Start a free trial on openseo.so

    Create an account and spend starter credits on a keyword or domain check before committing to a plan.

  2. Run keyword and domain research

    Seed keyword research, save opportunities, then open domain overview or backlinks for competitors.

  3. Track ranks and audit pages

    Add tracked keywords and run site audits so technical issues sit next to ranking data.

  4. Connect MCP to your agent

    Wire OpenSEO MCP (and Search Console MCP when needed) so Claude, Codex, or similar clients query live SEO data.

  5. Watch usage credits

    API-backed actions spend credits; top up if you hit the monthly included balance—projects and stored data do not bill again.

Who OpenSEO is for

Teams that want SEO data usable by both humans and agents.
  • Indie founders and small SEO teams

    Need keyword, backlink, and audit data without enterprise suite pricing.

  • Developers building agent workflows

    Want MCP tools for open source SEO research and Search Console inside Claude or Codex.

  • Self-host and open-source advocates

    Prefer customizable, GitHub-backed tooling over closed SaaS-only platforms.

When OpenSEO is the right pick

Choose OpenSEO when you want open source SEO software with agent MCP hooks and credit-based research data. Skip it when you only need a one-click free backlink check or a closed enterprise link index without self-host options.

Licensing and platform notes

Facts to verify on openseo.so before you depend on a workflow.
DataForSEO-backed queries
Credit spend applies to live API features (keywords, backlinks, audits, and similar)—not to viewing already-fetched workspace data.
MCP-first agent design
OpenSEO positions MCP as a first-class path for agents; confirm supported clients and tool lists in docs.
Self-host vs hosted
The marketing site and GitHub emphasize open source self-hosting; hosted billing and credits apply to the cloud product.
Free backlink checker vs full suite
A separate free backlink checker is listed under free tools—the curated platform page covers the full open source SEO product, not that single utility alone.
