SEO tools for developers
Validate meta tags, OG tags, and descriptions from the terminal. Free, open-source, and CI/CD ready.
Meta Tags Checker
Validate title tags, descriptions, Open Graph, canonical URLs, and JSON-LD from the CLI. One command, zero config.
OG Tags Checker
Validate og:title, og:description, og:image, og:url, and Twitter Card tags. Catch broken social previews before deploy.
Meta Description Checker
Check description length (120-160 chars), detect duplicates, and find missing descriptions across all pages.
Why CLI-first SEO tools?
Most SEO tools are browser-based dashboards built for marketers. You paste a URL, wait for results, and manually review each page. That workflow does not scale for developers who ship dozens of pages per sprint across multiple projects.
Indxel's tools run in your terminal. One command validates every page on your site against 15+ SEO rules in seconds. Add --ci to fail builds on broken metadata. Add --diff to see what changed between deploys. No browser, no signup, no API key required.
Each tool focuses on a specific aspect of SEO validation. The Meta Tags Checker validates title tags, descriptions, canonical URLs, and structured data. The OG Tags Checker validates Open Graph and Twitter Card tags for social previews. The Meta Description Checker focuses on description length, duplicates, and missing descriptions across all pages.
All tools are free, open-source, and work with any framework — Next.js, Nuxt, Astro, Remix, or any site accessible via URL. Run them locally during development or in your CI/CD pipeline for automated validation.
Frequently asked questions
Are these tools really free?
Yes. The CLI and all validation tools are free and open-source under the MIT license. No signup, no API key, no usage limits. The paid plans add the cloud dashboard, auto-indexation, and team features.
Do I need to install anything?
No. Run npx indxel check directly — npx downloads and runs it without a permanent install. For faster subsequent runs, install as a dev dependency with npm install -D indxel-cli.
What frameworks are supported?
All of them. The CLI validates the rendered HTML output, so it works with Next.js, Nuxt, Astro, Remix, Gatsby, Hugo, and any site accessible via URL. Framework-specific features like static analysis are available for Next.js today, with more frameworks coming soon.
