What crawler4seo does better

- Local-first: your SQLite database stays on your machine — Lumar is cloud-only
- Ship audits same-day — download, crawl, analyze. Lumar requires onboarding + contracts

- Full Schema.org Rich Results eligibility + hreflang cluster drilldown by default
Lumar's strengths

- •Team collaboration, role-based access, shared dashboards

Frequently asked questions
Things people ask before switching.
Is crawler4seo really free compared to Lumar?+
Yes. crawler4seo is free to download and use with no URL limit during early access — you don't need a credit card or an account. Lumar requires Enterprise — on request.
Does crawler4seo run locally or in the cloud?+
crawler4seo is a desktop app (Electron) that runs 100% on your machine. Your crawl data is stored in a local SQLite database and never leaves your computer. The only outbound traffic is the target site you crawl and an optional Google PageSpeed API call for Core Web Vitals.
Can I replace Lumar with crawler4seo?+
For most technical SEO audit workflows — yes. crawler4seo ships 20 analyzers (including a GEO audit for AI-engine readiness), internal-link graph with PageRank, Schema.org Rich Results eligibility, hreflang reciprocity, Core Web Vitals, sitemap coverage, crawl diffing and scheduled crawls. If your use case depends on Lumar-specific integrations we don't cover, you can run both side-by-side — crawler4seo is free.
What does "MCP integration" mean, and why does it matter?+
MCP (Model Context Protocol) is Anthropic's open protocol that lets AI assistants like Claude securely call tools on your machine. crawler4seo ships an MCP server, so you can point Claude at your crawl and ask questions like "which pages lost PageRank since yesterday?" or "list all Product pages with invalid Schema.org". No other crawler in this category ships this natively.
What platforms does crawler4seo support?+
macOS (Intel and Apple Silicon), Windows 10/11 (64-bit) and Linux (AppImage). All builds are free during early access.
Does crawler4seo support team collaboration like Lumar?+
Not natively — crawler4seo is desktop-first and optimized for individual SEO consultants and small teams. If you need shared dashboards, role-based access and multi-user collaboration at enterprise scale, Lumar is a better fit.
Can crawler4seo handle the site sizes Lumar targets?+
crawler4seo is great for sites up to a few hundred thousand URLs. Lumar is designed for millions of URLs with distributed cloud crawling — different segment, different tool.
