Can AI read your site?

Which AI crawlers your robots.txt allows and which it turns away — citing the rule that decides each one — plus whether your content survives without JavaScript.

10 agents, with the deciding rule

URL to Markdown

Paste a link, get clean Markdown for your LLM context — with the token count before and after, so you can see what the HTML was costing you.

six lines of backend

Website to Markdown

Convert a page to Markdown, then keep clicking — every hyperlink is rewritten to run back through the converter, so the whole site stays Markdown.

the links still work

Page to JSON

One page as structured JSON — title, H1, description, plain text, every link with the words people click, and every image with its alt text.

anchor text and alt text included

Website to JSON

Give it a domain. It reads the sitemap, walks up to 50 pages, and returns every page's title, H1, description and Markdown as one JSON document.

thirty-five lines of backend

URL to YAML

Paste a link, get the page as structured YAML — its H1, meta description, every Open Graph tag and the body text. Handy for checking what a link will look like when someone shares it.

thirty-two lines of backend

llms.txt generator

Give it a domain. It reads the sitemap and writes the site's llms.txt from the headings and descriptions those pages already publish — no model, so nothing invented.

twenty-eight lines of backend

Website image gallery

Collects every image across a site into one gallery you can click through, each captioned with its alt text — and the ones without any are flagged in red.

one crawl, one lightbox

Link preview checker

See the card Slack, X, LinkedIn and Facebook will build from your link — and what is missing from the tags — before you post it somewhere you cannot edit.

checks your image loads, too

Dead link checker

Opens the first ten pages in your sitemap, follows every link on them, and reports only the ones that failed — separating genuinely broken from merely blocked.

first 10 pages, every link on them

Why these exist

Every tool here started as one sentence handed to the Hyperlambda Generator, which wrote the endpoint, verified every function in it against the live registry, and deployed it. No project scaffold, no build step, no redeploy. That is the same path your own backend would take.

And because every endpoint on a Magic cloudlet is also an MCP tool filtered by role, anything you build this way is immediately callable by your own AI agents, carrying their identity rather than a shared key.

If you would rather watch the runtime refuse something instead, the Natural Language API executes any sentence you type inside a whitelisted sandbox, and pays $100 to anyone who escapes it.

Run the whole platform on your own hardware in one command:

curl -fsSL https://hyperlambda.dev/docker-compose.yaml | docker compose -f - up

Suggest a tool

Got something you keep doing by hand that ought to be a box on a page? Tell me what it is. These take an afternoon at most, they cost nothing to host, and the ones on this page all started as somebody wanting them — so a good suggestion has a decent chance of simply appearing here.
