About OpenSEO

What the tool does and who it's for

OpenSEO is an all-in-one open source alternative to Semrush and Ahrefs. Built for individuals, teams, and AI agents, it eliminates expensive monthly subscriptions by replacing them with a pay-as-you-go architecture using DataForSEO APIs. It supports Model Context Protocol (MCP) and pre-built agent skills to allow AI agents to research keywords, analyze competitors, inspect backlinks, track ranks, and conduct site audits on real data.

Key capabilities

Keyword Research: Fetch accurate search volume, difficulty, and traffic metrics powered by DataForSEO APIs.
Competitor Insights: Analyze organic search visibility and discover keywords your competitors rank for.
Backlink Analysis: Track link profiles, referring domains, and explore link prospecting workflows.
Rank Tracking: Monitor search performance and position shifts for targeted keywords over time.
Site Audits: Run technical audits to surface errors and clean up code or UX friction affecting SEO performance.
Model Context Protocol (MCP): Connect with any AI agent (like Claude Code, OpenClaw, or Hermes) to supply it with real SEO data.
OpenSEO Agent Skills: Utilize pre-built reusable workflows such as keyword-clustering, seo-coach, and link-prospecting.
Flexible Deployment: Supports local development or production hosting via Docker and Cloudflare Workers.
