> ESLint for SEO. Infrastructure SEO developer-first.

indxel is an open-source SEO infrastructure toolkit for developers building with Next.js.
It provides an npm SDK, a CLI, and a monitoring dashboard to ensure SEO never breaks silently.

## Core concept

SEO breaks silently. A missing og:image, a truncated title, a wrong canonical -- you don't notice until traffic drops. indxel makes SEO failures loud: every page gets a 0-100 score, every deploy gets a gate.

## Components

- **indxel** (npm package): TypeScript SDK for defining metadata, generating JSON-LD, validating SEO, crawling sites, and researching keywords.
- **indxel-cli** (npm package): CLI tool for SEO audits, crawling, keyword research, indexation, and CI/CD gating.
- **indxel-mcp** (npm package): MCP server for AI assistants (Claude, Cursor) to audit SEO in real-time.
- **indxel.com**: Dashboard for monitoring SEO scores over time with diff tracking between crawls.

## Quick start

```bash
npm install indxel           # SDK
npm install -g indxel-cli    # CLI

npx indxel-cli init          # scaffold seo.config.ts, sitemap.ts, robots.ts
npx indxel-cli check         # audit your Next.js pages
npx indxel-cli crawl mysite.com  # crawl a live site
```
