Hi Product Hunt. I built it because every technical SEO audit I did started the same way: run a crawler, export a spreadsheet, then spend the afternoon working out what each error name actually means and which of the 400 flagged URLs matter. The tools that do this well cost agency money, and the free ones stop at a list. Crawlune is a desktop crawler for macOS, Windows and Linux. You enter a URL, it crawls the site from your machine, and every one of its 150+ checks comes with why it matters and how to fix it, next to the affected URLs and the page source to prove it. Nothing is uploaded anywhere. The raw HTML of every page stays on your computer. What I think makes it different: An action plan that ranks issues by the health points a fix recovers, weighted to your best-linked pages, so you fix the right thing first. Server log files joined to the crawl, with Googlebot verified by IP, so you can see which pages Google never fetches. Search Console, GA4 and PageSpeed data next to each URL. A built-in MCP server and local API, so Claude or your own scripts can run crawls and read the results. A CLI with a CI mode that fails a build on new SEO errors, with JUnit and SARIF output. White-label PDF reports, scheduled crawls, Slack alerts, and compare-two-crawls to prove a fix landed. It is written in Rust, so 500 pages take seconds. Free up to 550 URLs per crawl with every check enabled, no account needed. Pro removes the cap and adds the integrations and automation: $19 a month, $189 a year, or $499 once, with a 14-day trial and no card. This is an early release and I’m the only person behind it, so I’ll be in the comments all day. If you run it on your site and something is wrong, confusing or missing, tell me here. That feedback decides what gets built next. Download: https://crawlune.com/download/?r... Every check it runs: https://crawlune.com/checks/?ref=ph
