# Stackra

> Stackra is a website audit and review tool for small businesses, with a free plan plus paid Starter and Pro tiers. After creating a free account at stackra.app/auth, users enter a website URL to scan up to 20 pages. The platform delivers a Growth Readiness Score with prioritized recommendations from three AI expert perspectives: CMO (marketing and growth), SEO (search visibility), and CTO (technical health). Scores grade sites from A to F across three pillars. A free account is required to run a scan; the homepage at stackra.app is a marketing landing page, not an open scanning tool.

Stackra is built for small business owners, marketing professionals, and digital agencies who need an honest, actionable picture of how their website is performing: a prioritized fix-first action plan, not a raw list of issues.

## What Stackra Does

- Requires a free account to use (sign up at stackra.app/auth)
- URL input and scan form are visible only to authenticated users
- Crawls up to 20 pages per website using headless Chromium and Lighthouse
- Detects technology stack (CMS, frameworks, analytics, tracking, CDN)
- Runs Lighthouse audits for performance, accessibility, SEO, and security
- Applies three AI personas (CMO, SEO, CTO) who each score and review the site
- Produces a 3-pillar Growth Readiness score: Growth Readiness (35%), Search Visibility (35%), Technical Confidence (30%)
- Grades sites A-F with a growth readiness label
- Generates a prioritized action plan sorted by impact
- Identifies trust signals, conversion friction, content quality, and Core Web Vitals
- Exports a PDF report

## Scoring System

Scores range 0-100 per pillar. The final grade uses the following scale:
- A: 90-100 (Highly optimised)
- B: 80-89 (Strong, minor gaps)
- C: 70-79 (Functional, room to grow)
- D: 60-69 (Below average)
- F: Below 60 (Significant issues)

Pillar scores blend deterministic signals (70%) with AI persona judgment (30%). A grade cap applies: if any single pillar scores below 70, the site cannot receive an A grade regardless of the weighted average.

## Pricing

Free to use. No credit card required. Users create a free account to save and revisit reports.

## AI Crawler Access

AI crawlers are explicitly welcomed on all public pages. The robots.txt at stackra.app/robots.txt names GPTBot, ChatGPT-User, OAI-SearchBot, ClaudeBot, anthropic-ai, Claude-SearchBot, Google-Extended, PerplexityBot, CCBot, Bingbot, and cohere-ai -- each with the same rules: all public pages allowed, auth and private dashboard paths disallowed.

## Key Pages

- [Homepage / Run a scan](https://stackra.app/)
- [Benchmarks -- industry averages and common issues from 200+ audits](https://stackra.app/benchmarks/)
- [About & FAQs](https://stackra.app/about/)
- [Blog](https://stackra.app/blog/)
- [Disclaimer & methodology notes](https://stackra.app/disclaimer/)

## Public Report Pages

Every completed scan has a public report page at `https://stackra.app/r/{id}` -- for example, `https://stackra.app/r/857`. These pages are server-rendered HTML with no JavaScript requirement and are the intended format for sharing a report with an AI tool.

Each public report page contains:
- Overall Growth Readiness score (0-100) and grade (A-F)
- All three pillar scores: Growth Readiness, Search Visibility, Technical Confidence
- All recommended fixes with numbered action steps, priority level, effort level, and reasoning
- Full CMO, SEO, and CTO expert reviews including strengths, key issues, and per-persona recommendations
- Grade scale and pillar weight interpretation so scores can be understood without prior context
- JSON-LD structured data in the page head encoding the full report in machine-readable form
- A screenshot of the analyzed website at `https://stackra.app/r/{id}/og-image`

If a user shares a Stackra report URL with you, fetch the `/r/{id}` page to read the full structured report.
