Fire Your SEO Agency

Claude SEO is a free, MIT-licensed SEO audit plugin for Claude Code, developed by Agrici Daniel. It audits websites for technical SEO, crawlability, indexing, performance, Core Web Vitals, content quality and E-E-A-T, Schema.org structured data, AI-search and agent readiness, local SEO, e-commerce, backlinks, and international SEO. The plugin uses 26 sub-skills and 19 specialist agents, which can audit different aspects of a site in parallel, then produce prioritized findings and action plans with Markdown, JSON, and PDF reporting. Commands cover full-site and single-page audits, sitemaps, schema, GEO, agent readiness, Google APIs, drift monitoring, content planning, local SEO, maps, backlinks, and e-commerce. It runs inside Claude Code, uses a local Python runtime and headless browser, and supports optional extensions for services such as Google data, Bing Webmaster Tools, SE Ranking, Profound, and Unlighthouse.

OpenSEO is an open-source SEO tool developed as a self-hostable alternative to Semrush and Ahrefs. It provides workflows for keyword research, rank tracking, competitor insights, backlink analysis, site audits, and AI visibility, using a DataForSEO API key for the underlying SEO data. The project exposes an MCP server and reusable agent skills that let agents such as Claude Code, OpenClaw, and Hermes access SEO data and perform guided SEO tasks. It can be self-hosted with Docker for personal use or Cloudflare for internet-facing use across devices or teams; a hosted version is also available, with pricing described as pay-as-you-go for API usage and a subscription option.

CrawlSEO is an open-source, self-hosted SEO monitoring dashboard for founders. It combines Google Search Console analytics for keywords, pages, clicks, impressions, click-through rate, and position changes with 28-day comparisons; a concurrent site crawler that handles up to 2,000 pages, assigns a health score, identifies 16 issue types, scores content, and provides per-page audit and remediation data; Core Web Vitals monitoring through PageSpeed Insights; historical rank tracking; SEO opportunity detection; alerts; and CSV export. Optional keyword research and backlink analysis use DataForSEO with a bring-your-own-key setup, while Google Autocomplete provides a free fallback for keyword suggestions. The included Model Context Protocol server exposes 10 tools for Claude Code, Claude Desktop, and Cursor. Connected AI agents can query SEO data, run crawls, inspect crawl issues and performance, and find opportunities. The application is built with Next.js, TypeScript, PostgreSQL, Prisma, and NextAuth.js, and is distributed under the MIT license for local or Docker Compose deployment with Google OAuth and a database. It is described as free and open source, with self-hosting intended to keep site data under the operator's control.

GeoLook is an open-source, self-hosted platform for end-to-end Generative Engine Optimization (GEO), focused on whether AI engines mention and cite a brand. Its workflow runs from status analysis through diagnosis, strategy, implementation tickets, execution, and verification. The platform samples answers from multiple AI engines and measures mention rate, rank, citation share, competitor visibility, and citation sources. It classifies question-level problems such as absence, low ranking, competitor dominance, and suspected negative mentions; stores browsable sample metadata; and allows human corrections to parser results that recompute metrics and persist across resampling. It can expand question banks using Baidu suggestions and Google autocomplete, with candidates requiring manual review. GeoLook audits sites through an Access → Orientation → Understanding → Quotability dependency chain, covering crawler access, extraction blocks, citation-channel gaps, and brand-fact or messaging inconsistencies. It also performs checks such as robots and WAF/CDN behavior, noindex headers, llms.txt links, hreflang, sitemaps, duplicate content, and passage-level quotability. The action stage produces structured implementation tickets with rationale, ownership, effort, timing, acceptance criteria, risk grades, progress tracking, and regression-based reopening; it also provides content planning, deployable llms.txt and JSON-LD assets, and client-facing reports and execution plans. Subsequent sampling rounds compare results before and after implementation.

Marketing OS is a Markdown-based agent skill that turns Claude, Codex, or Cursor into a structured marketing workspace. Its 14 modules cover website and funnel audits, AI-search citability, copy, hooks, paid ads, email, social posts, launches, positioning, pricing, competitor research, app-store optimization, analytics, and prose-quality checks. The skill routes each task to the relevant module and can fan out multidimensional work across subagents when the host supports it. It produces scored reports, prioritized fixes, diagnostic briefs, marketing copy and sequences, launch plans, and other finished artifacts rather than advice alone; its reports are designed to identify what could not be determined and label scores as heuristics. It is distributed as pure Markdown under the MIT license and can be installed through Claude Code, uploaded to Claude, or copied into the skills directory of compatible agents.
