11 free tools for reading any website

Built from the same engine as the extension. Each one answers a single question about a page — what it is built with, what fonts and colours it uses, whether its tags and structured data are right, what it makes a browser download — and none of them need an account.

Website tech checker

Paste a URL and see the CMS, framework, CSS system, analytics and third-party scripts a site actually serves, read straight from its HTML. Free, no signup.

Free · no signup

Font finder

Find every font a website uses: @font-face families, weights, file names, font-display behaviour and font services. Free, reads real CSS, no signup.

Free · no signup

Colour palette extractor

Pull every colour a website uses out of its real CSS, ranked by how often it appears, with the site’s CSS custom properties. Export as CSS variables or JSON.

Free · no signup

Meta tag checker

Audit the tags that decide how a page appears in search: title and description length, canonical, robots, lang, schema and headings.

Free · no signup

See the image, title and description a link shows on social platforms, with every Open Graph and Twitter tag listed and the missing ones flagged. Free, instant.

Free · no signup

CSS extractor

Free · no signup

HTML to Gutenberg converter

Paste HTML and get core WordPress block markup back — headings, paragraphs, lists, images, quotes, code and tables — ready to paste into the block editor.

Free · no signup

Robots & sitemap checker

Read any site’s robots.txt, see the rules per crawler, whether GPTBot, ClaudeBot and PerplexityBot are allowed, and how many URLs its sitemaps declare.

Free · no signup

Page weight checker

Measure a page’s HTML size, render-blocking stylesheets and image markup, and find the missing dimensions and lazy-loading that cause layout shift.

Free · no signup

Heading structure checker

See a page’s heading outline the way a crawler and a screen reader read it, with multiple-H1 and skipped-level problems flagged. Free, instant.

Free · no signup

Schema markup checker

See every JSON-LD block and microdata type on a page, catch invalid JSON, and check for the Organization, FAQ, Breadcrumb and Article markup AI search relies on.

Free · no signup

Why these are free

Because they are the parts of CopyAnySite that fit in a page. The extension exists to rebuild a whole site at measured fidelity; reading one page’s fonts, colours, tags or stylesheets is a by-product of that engine, and a by-product is a poor thing to charge for.

Every tool runs the read through our Cloudflare Worker — GET only, public URLs only, cached briefly, nothing stored — except the Gutenberg converter, which never leaves your browser at all.
