## What it is

An open source SEO tool with keyword research, rank tracking, competitor and backlink analysis, site audits and AI-visibility workflows.

## What it’s for

Use it to do SEO research and operations on your own or inside an agent workflow.

## Benefits

- Keyword research, rank tracking, backlinks and site audits in the same repository
- MCP server and Agent Skills so agents can access SEO data
- Self-hosting with Docker or Cloudflare, with accounts for teams

## Caveats

- MIT license; self-hosting requires a DataForSEO key, billed by usage
- The hosted version lists a US$ 10 per month subscription, with a 28% markup on DataForSEO requests
