@webanalyzer/cli

Official SDK + CLI for webanalyzer.dev — score any public web page 0–100 across 8 quality dimensions (SEO, GEO/AI readiness, performance, accessibility, code quality, UI/UX, data & tracking, security) from 290+ deterministic checks. Free, keyless, no signup.

CLI

npx @webanalyzer/cli https://example.com

Or install it globally and use the short command:

npm i -g @webanalyzer/cli
webanalyzer https://example.com
 62/100  grade C  https://example.com/

   71  SEO
   55  AI readiness
   …

top issues:
  - [SEO] Meta description missing

webanalyzer leaderboard shows the public leaderboard; --json prints raw API output.

SDK

import { analyze, leaderboard } from "@webanalyzer/cli";

const report = await analyze("https://example.com");
console.log(report.score, report.grade); // e.g. 62 "C"

Zero dependencies, Node 18+. Errors throw WebAnalyzerError with a stable .code (rate_limited, fetch_failed, blocked_host, …).

Notes

  • The API is rate-limited per IP (8 analyses/min) and returns standard RateLimit-* headers.
  • Scores use a deliberately demanding curve with critical caps — a 70 is a good site. Not comparable with linear percentage graders.
