Install in one line

Scrawly installs itself, adds an app icon (Applications on macOS, the Start Menu on Windows, your app menu on Linux), and keeps itself up to date.

macOS or Linux (Terminal):

curl -fsSL https://raw.githubusercontent.com/IliasSami/scrawly-seo-crawler/main/install.sh | bash

Windows (PowerShell):

irm https://raw.githubusercontent.com/IliasSami/scrawly-seo-crawler/main/install.ps1 | iex

Then open Scrawly like any other app. There is nothing to sign up for.

git clone https://github.com/IliasSami/scrawly-seo-crawler.git Scrawlycd Scrawlypython3 scripts/install.py        # Windows: py scripts\install.py

What Scrawly checks

Scrawly runs 250 checks grouped into 23 areas. Every finding comes with why it matters, how to fix it, and the exact pages affected.

The full catalogue, with severity and fix tier for every check, is in docs/CHECK_MANIFEST.yaml.

Also included: JavaScript rendering, custom extraction, saved crawl profiles, a 3D site graph and depth tree, crawl-to-crawl comparison, scheduled audits with regression alerts, Google Search Console and GA4 data, branded HTML and PDF reports, an AI writer for titles and meta descriptions (bring your own AI key), and an MCP server so AI assistants can work with your audits (docs/MCP.md).

A free alternative to Screaming Frog and Sitebulb

Screaming Frog SEO Spider and Sitebulb are excellent tools. Scrawly is a free, open-source option for people who want a deep technical audit without a licence, plus checks for AI search.

Scrawly is independent and not affiliated with Screaming Frog Ltd or Sitebulb.

GEO and AEO: auditing for AI search

Search now includes AI answer engines that read your pages and decide whether to cite you. Scrawly audits for Generative Engine Optimization (GEO) and Answer Engine Optimization (AEO):

• AI crawler access: a matrix of which AI bots (GPTBot, ClaudeBot, PerplexityBot, Google-Extended, OAI-SearchBot and others) your robots.txt and firewall allow or block.
• llms.txt: whether you publish a curated index for AI systems, and its quality.
• Meta as AI context: a description is often the first thing an AI reads about a page, so Scrawly flags descriptions too thin to understand and can draft an entity-rich one from the page's own content.
• Entities and structured data: the schema and named entities that help search engines and AI understand what a page is about.

Fix WordPress issues safely

Connect a WordPress site with the lightweight Scrawly Connector plugin and Scrawly can fix titles, meta descriptions, canonicals and redirects for you:

• a rollback snapshot is saved before every change, and every fix can be undone;
• changes to the live site always ask for your confirmation first;
• higher-risk issues are never auto-applied; they're flagged for a person to review.

See docs/WORDPRESS_CONNECTOR.md. Every other site (Shopify, Wix, Webflow, Next.js, custom) gets the full read-only audit.

Privacy: your audits stay on your computer

Scrawly has no accounts and no analytics. Your crawls, findings and reports are stored on your computer only. Scrawly connects to:

• the websites you choose to audit;
• GitHub, to check for updates (turn off with SCRAWLY_AUTO_UPDATE=0);
• services you configure, such as PageSpeed Insights, Google Search Console or your AI provider;
• the feedback service, only when you click Send on a feedback note.

The app's local engine only accepts requests from the Scrawly window itself, so other websites can't use it. Report security issues as described in SECURITY.md.
