Best for free crawls with no URL cap on your own machine
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.
Who LibreCrawl is for
- Fits if you want a crawler with no URL limit and no licence fee
- Works for agencies hosting one crawler for a whole team on their own server
Who LibreCrawl is not for
- Skip it if you don't want to install anything, as there's no hosted version and the demo is down
- Watch out: on Windows the automatic Python install is off, so you need Docker or a manual setup
- Not for you if you'll put it on a shared network as it comes, since it runs without sign-in by default
- Watch out: one developer maintains it with outside help, and support goes through GitHub
Why LibreCrawl gets a 2.6
Five grades, each with its reason. The GPA is their average: an A is 4 points, an F is none.
- AValue for moneyFree 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.
- AFree plan and trialEvery feature is free, including JavaScript rendering, unlimited exports and multi-user sessions. The only limit on crawl size is your hardware.
- CFeaturesBroken 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.
- DEase of useNo 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.
- CPlatforms and integrationsWindows, 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.

Keep LibreCrawl, or make your own?
Keep it
LibreCrawl is free, so making your own would save you nothing.
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.
What you could not
- A crawler that checks every page of a site.
- Apps for macOS, Windows and Linux that stay in step with each other.
- It plugs into other products, PageSpeed Insights, Playwright and Docker among them, and has an API.
What this rests on. LibreCrawl’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
What is LibreCrawl?
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.
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.
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.
