# LibreCrawl review (2026): is it any good? > Free open-source SEO crawler you run in your own browser Checked Oct 23, 2026 ยท graded Oct 23, 2026 by ToolGPA. LibreCrawl is an MIT-licensed SEO crawler built as a Python web application that you install on your own computer or server and use in a browser. It audits titles, links, redirects, schema markup, hreflang, canonicals and page speed, can render JavaScript sites with Playwright, and has no URL limit. Several people can crawl at once in separate sessions, and plugins add new tabs. - **Category:** Technical SEO & Site Audits - **Made by:** PhialsBasement - **Website:** https://librecrawl.com - **Runs on:** Web, Windows, macOS, Linux - **Who should skip it:** Skip it if you don't want to install anything, as there's no hosted version and the demo is down. - **Facts last checked:** Oct 23, 2026 ## Pricing As of Oct 23, 2026, LibreCrawl is free to use. - **Pricing model:** Free - **Free plan:** Free and open source under the MIT license with no URL limit; the project says it will never have paid tiers or subscriptions. - **Free trial:** None listed. | Plan | Price | What you get | | --- | --- | --- | | Free | $0 | The full crawler, which you install and host yourself with Docker or Python. Every feature is included. | Read from https://librecrawl.com/about.html on Oct 23, 2026. Prices change, so confirm with LibreCrawl before buying. ## Key features - **Technical SEO checks:** Finds broken links, redirect chains and loops, duplicate content, title and meta problems, schema errors, hreflang and canonical issues, and missing alt text. - **JavaScript rendering:** Uses Playwright and Chromium to crawl React, Vue, Angular and Next.js sites, in headless mode for speed or headed mode for debugging. - **Large crawls:** No URL cap; memory profiling and virtual scrolling are there to keep crawls of a million or more URLs stable, with the limit set by your hardware. - **Exports:** Export crawl data as CSV, Excel, JSON or XML, picking the fields you want, with no limit on the number or size of exports. - **Multi-user sessions:** Several users can crawl at the same time in separate sessions; a production mode adds sign-in and user tiers, and a local mode skips them. - **Plugins and REST API:** A plugin is one JavaScript file that adds a tab with the crawl data, shared through a Plugin Workshop; a REST API starts, stops and exports crawls. ## Good for - SEOs who want a crawler with no URL limit and no licence fee - Agencies hosting one crawler for a whole team - Developers auditing JavaScript-heavy sites ## Worth knowing - There is no hosted version: you install it with Docker or Python 3.8 or later, and the public demo has been taken down. - On Windows the startup script's automatic Python install is temporarily disabled, so Docker or a manual Python setup is needed. - It runs in local mode without sign-in by default; sharing it on a network means setting a secret key and turning authentication on. - It is maintained by one developer, PhialsBasement, with outside contributors; bugs and feature requests go through GitHub. ## ToolGPA grades **GPA: 2.6 out of 4**, graded Oct 23, 2026. LibreCrawl is a free, MIT-licensed crawler you install yourself and use in a browser, with JavaScript rendering, no URL limit, exports and a REST API. But there's no hosted version, setup means Docker or Python, and it's one developer's project, with bugs and requests handled on GitHub. - **Value for money: A.** Free under MIT with no URL limit, and the project says it will never have paid tiers. It runs on your own computer with Docker or Python, so there's nothing to rent for a crawl. - **Free plan and trial: A.** Every feature is free, including JavaScript rendering, unlimited exports and multi-user sessions. The only limit on crawl size is your hardware. - **Features: C.** Broken links, redirect chains, duplicates, titles and meta, schema, hreflang, canonicals and alt text, with Playwright rendering, PageSpeed data and plugins. The gaps: no scheduled crawls, crawl comparison or Search Console data on record. - **Ease of use: D.** No rating on record. You install it with Docker or Python 3.8 or later, and on Windows the startup script's automatic Python install is turned off for now. Sharing it on a network means setting a secret key and turning sign-in on. - **Platforms and integrations: C.** Windows, Mac and Linux, used through a browser on the machine running it, with a REST API, PageSpeed Insights and Playwright. A program for computers only: no hosted or phone version. These are ToolGPA's own grades. Graded from this listing, whose facts were read from LibreCrawl's own pages on 23 October 2026.

And it is not the kind of software a weekend replaces. It is one of the better ones too: its GPA of 2.6 is higher than 56 of the 83 other technical SEO tools we grade. - You could not: A crawler that checks every page of a site. - You could not: Apps for macOS, Windows and Linux that stay in step with each other. - You could not: It plugs into other products, PageSpeed Insights, Playwright and Docker among them, and has an API. A judgement by ToolGPA from this listing, by rules that are the same for every tool.
