Free forever — just paste your URL

LANGR your site

Q: What is LANGR?

LANGR is a free SEO engine — like Google, but for fixing your SEO. Paste any URL, get a full report in 60 seconds. Paid plans put your SEO on autopilot: daily monitoring, automatic fixes, rank tracking. Everything an agency does — without the agency.

Q: Is the free audit really free?

Yes. No account, no credit card, no catch. Scan as many sites as you want. The free audit runs the same 29-module engine that powers paid plans.

Q: Why not just hire an SEO agency?

Most agencies use tools like LANGR — then sell you the output at 5-10x markup. With LANGR you connect your own credentials directly and get the same daily optimization on autopilot. Same tools, same data, no middleman.

Q: What credentials do you need?

For the free scan: nothing. For paid plans: Google Search Console and Analytics via OAuth. The same access your agency already has. You control what we see and can revoke anytime.

Q: Do you touch my code or website?

No. The free audit scans your site externally — as Google sees it. Paid plans optimize meta tags via a proxy, so your code and CMS remain untouched. You stay in full control.

Q: What happens after the trial?

Your subscription starts automatically after 14 days. Cancel before, and you pay nothing — your free audit continues as always.

Q: Is my data safe?

We only analyze publicly available data from your website — the same as Google sees. All communication is over HTTPS, and we never sell your data.

Your SEO agency uses tools like this — and charges you 10x. Paste any URL, get a full report in 60 seconds. Or hand us your credentials and let AI handle the rest.

What is LANGR SEO?

LANGR SEO is a free, online SEO audit tool that scans any website and delivers a complete technical SEO report in under 60 seconds. The tool runs 29 specialized modules with a combined 290 individual checks, covering everything from page speed and accessibility to security, meta tags, structured data, and crawl budget.

Each analysis generates six separate scores: performance, SEO, accessibility, best practices, security, and an overall score. Results include a prioritized list of issues with actionable recommendations, so you know exactly what to fix and in what order. Reports can be shared via link, sent as a PDF by email, or downloaded as JSON data.

LANGR SEO is built for everyone — from small business owners who want to improve their search visibility to SEO consultants and agencies that need fast technical audits of client websites. The tool requires no registration and is completely free to use. For businesses that want ongoing monitoring, we offer paid plans with daily scans, rank tracking, AI-generated fixes, and automatic optimization.

All scans run in real time directly from our servers. We use Lighthouse, Google PageSpeed Insights, and AI-powered analysis to give you the most complete picture of your website's technical health. Results are cached for 24 hours, and you can schedule daily automated scans to track changes over time.
