# Free Hreflang Checker - Alternate Language Tags

> Extract rel=alternate hreflang links from a page. See each language code and href, and get warnings for missing x-default or duplicate langs.

```yaml
url: "https://www.scrolllaunch.com/tools/hreflang-checker"
slug: hreflang-checker
category: onpage
keywords: "hreflang checker, hreflang tester, hreflang tag checker, international seo hreflang, x-default hreflang"
```

## How to use

1. **Paste a locale URL** - The page that should declare its alternates.
2. **Read the table** - Every hreflang code and target href.
3. **Fix warnings** - Add x-default, remove duplicates, then confirm canonicals.

## How to check hreflang without a crawl

Hreflang tells search engines which URL is for which language or region. This tool reads the tags on one page - it does not fetch every locale to confirm return links.

Include x-default as a fallback. Avoid two hrefs for the same language code on one page.

Canonical and hreflang should agree. A locale URL that canonicalises to another language will fight itself.

## What you get

- List hreflang + href
- x-default detection
- Duplicate language warnings
- CSV export
