The JetOctopus alternative that runs on your machine
Cloud-speed isn't everything: crawler4seo runs locally, costs nothing, and gives you graph + AI features JetOctopus doesn't ship.
What crawler4seo does better
- crawler4seo is free — JetOctopus starts around $200/month
- Your data never leaves your machine — JetOctopus is cloud-only
- Native link-graph metrics (PageRank, HITS) ship in the app — JetOctopus focuses on aggregate dashboards
- Schema.org per-type eligibility + hreflang reciprocity auditing with cluster drilldown
- MCP server for AI-native SEO analysis — conversational queries against your crawl
JetOctopus's strengths
- •Extremely fast cloud crawling (up to 200 pages/second on large sites)
- •No crawl limits, no project limits on paid plans
- •Log analyzer bundled with the crawler
- •Clean dashboards with good big-site tooling
We try to stay honest — if one of these matters more than free + local + AI-native for your use case, JetOctopus is a legitimate choice.

Frequently asked questions
Things people ask before switching.
Is crawler4seo really free compared to JetOctopus?+
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. JetOctopus requires SaaS — from ~$200/mo.
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 JetOctopus 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 JetOctopus-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.
Is crawler4seo fast enough without cloud infrastructure?+
For sites up to a few hundred thousand URLs, yes — crawler4seo runs in parallel workers and stores to SQLite. JetOctopus's 200 pages/second matters for sites in the millions; for most SEO audits, local crawling is faster overall because there's no upload/render queue.
Can I keep a history of crawls like JetOctopus does?+
Yes. crawler4seo stores every crawl in a local SQLite database and includes built-in crawl-to-crawl diffing (pages, issues, PageRank shifts) to catch regressions.
