Most website audit tools produce a Lighthouse report and leave you to figure out the rest. Stackra is different in three ways. It detects your platform: WordPress, Shopify, Wix, Squarespace, Webflow, and more. Then, It only surfaces fixes you can actually make on your setup. It runs three AI expert reviews in parallel: a CMO review checking whether your messaging, trust signals, and CTAs are working; an SEO+GEO review covering traditional search rankings and AI search visibility in ChatGPT, Perplexity; and a CTO review covering Core Web Vitals, performance, and security. Everything compiles into a Growth Readiness Score (0-100) with a ranked action plan. Not 47 issues.

What to fix first, and why. Free to sign up. Full report. 3 minutes.

Questions & Answers

As answered by people managing Composer and Stackra.app.

What makes your product unique?

Stackra.app's answer:

Most website audit tools hand you a Lighthouse report and walk away. Stackra is different in three ways. It knows your platform: Stackra detects whether your site runs on WordPress, Shopify, Wix, Squarespace, or Webflow and limits every recommendation to changes you can actually make on your specific setup. It reviews your site the way a consultant would: a CMO review checks messaging, trust signals, and CTAs; an SEO and GEO review covers traditional search and AI search visibility in ChatGPT and Perplexity; a CTO review covers Core Web Vitals, performance, and security. Then it tells you what to fix first: everything compiles into a Growth Readiness Score (0-100) and a prioritized action plan, not an exhaustive issue dump.

Why should a person choose your product over its competitors?

Stackra.app's answer:

Stackra is the only free website grader that covers platform-aware recommendations, AI search visibility (GEO), and three expert perspectives in one report. SEOptimer starts at $19/month with no free plan. Sitechecker starts at $49/month, trial only. HubSpot's Grader checks your homepage and gives you four scores. Stackra crawls up to 20 pages, detects your platform, and delivers three AI expert reviews with a ranked action plan. Free to start, no credit card required.

How would you describe the primary audience of your product?

Stackra.app's answer:

Small business owners, solo founders, and early-stage teams who want a clear diagnostic and action plan without agency costs or ongoing subscriptions. Typically owners and operators without an in-house marketing or technical team who want to know why their site isn't converting and what to do about it.

What's the story behind your product?

Stackra.app's answer:

Stackra came from a simple frustration: the best website analysis tools are built for SEO agencies running dozens of audits a month, not the business owner who wants to understand their own site. We built Stackra to give small businesses the same quality of analysis that larger companies pay consultants thousands of dollars for, free.

Which are the primary technologies used for building your product?

Stackra.app's answer:

Typescript, React, Node.js, PostgreSQL, Playwright for headless browser crawls, and OpenAI for the AI persona reviews.

Who are some of the biggest customers of your product?

Stackra.app's answer:

Stackra is a free tool built for SMB owners, so our users span local service businesses, e-commerce stores, professional services firms, and early-stage SaaS startups. We built it for the owner-operator, not the enterprise.

Composer mentions (152)

  • Cursor Introduces Composer 2.5
    It's very confusing that they use the same name as the very well known PHP package manager, composer https://getcomposer.org/. - Source: Hacker News / 3 months ago
  • Composer is just a console application
    I'm embarrassed I never took the time to understand Composer until now. I have been preaching for a long time to start each PHP project with Composer, even when the project is not going end up on Packagist. - Source: dev.to / 3 months ago
  • Publishing a PHP monorepo to Packagist with splitsh-lite
    Waaseyaa is a monorepo. The root composer.json defines 43 subpackages under packages/, each referenced as a path repository with @dev constraints. During development, this is convenient. Composer resolves everything locally, and you never think about versioning. - Source: dev.to / 4 months ago
  • Peer dependencies in (P)NPM
    (P)NPM is an outlier in this behavior compared to package managers of other languages. With package managers like Composer (PHP), pip (Python) and NuGet (.NET) dependencies are by default peer dependencies. That means that in those package managers it is not possible to have multiple versions of the same dependency in your application1. - Source: dev.to / 8 months ago
  • Build a Robust RESTful API with PHP 8, from Scratch Course!
    Download from getcomposer.org and follow installation instructions. - Source: dev.to / 10 months ago
