Open source alternative to Semrush and Ahrefs

What it solves

OpenSEO provides a cost-effective, open-source alternative to expensive SEO suites like Semrush and Ahrefs. It removes the bloat of traditional tools by offering focused workflows and a pay-as-you-go model where users provide their own API keys for data.

How it works

The tool integrates with the DataForSEO API to fetch search engine optimization data. It can be self-hosted via Docker or Cloudflare and offers a modern UI for manual use. Crucially, it implements a Model Context Protocol (MCP) server, allowing AI agents (such as Claude Code or Hermes) to access SEO data and execute predefined "Agent Skills" to automate SEO tasks.

Who it’s for

SEO professionals, website owners, and developers who want a customizable SEO tool that integrates directly with AI agents and avoids high monthly subscriptions.

Highlights

  • AI Agent Integration: Uses MCP to let AI agents interact with SEO data directly.
  • Pay-as-you-go: Users bring their own DataForSEO API key to avoid fixed subscriptions.
  • Flexible Hosting: Supports both simple Docker setups for personal use and Cloudflare for team-based hosting.
  • Core SEO Workflows: Includes keyword research, rank tracking, competitor insights, backlinks, site audits, and AI visibility tracking.
