Tools

Eighteen tools, built from the same code the product runs

Some run in your browser and send nothing anywhere. Some fetch a page on a server in the EU. Some open a real browser and report what it saw. Each page says which, what the tool computes, and what it does not judge.

Schedule

  • Cron expression generator

    Build a cron expression with an IANA time zone and see the next ten runs, including the nights the clocks change.

Consent

  • Cookie checker

    Which consent tool a page runs, whether Reject all is one click away, and what loads before you choose.

Extract

  • JSON Schema generator

    Turn example JSON into a schema you can hand to an extraction call, validated, with the matching request.

  • What the agent sees

    The element tree an agent reads for any URL, with clickability reasons and token costs at three fidelities.

  • Website to text

    The main content of a page as clean text or Markdown, with an estimated token count.

  • URL extractor

    Every link on a page and every URL its sitemap declares, grouped by same-site and external, as CSV or JSON.

  • Product data extractor

    Name, price, currency, availability and identifiers from a product page as JSON, filled by an EU-hosted model.

  • HTML to Markdown

    Clean Markdown with headings, lists, links and GFM tables from pasted HTML, converted in your browser.

  • Website screenshot

    A viewport or full-page capture of any URL from a real EU browser, cookie banner rejected first; also an API.

Verify

  • AI crawler checker

    What robots.txt allows GPTBot, ClaudeBot, Google-Extended and PerplexityBot, and whether an llms.txt follows the spec.

  • XPath tester

    Write an XPath against pasted HTML and see every match highlighted, shadow roots included, in your browser.

  • Effect classifier

    How the effect gates classify a button label or element before an agent may click, with the phrase that matched.

  • Audit log verifier

    Verify the hash chain and the signed seal of an action-log export locally with WebCrypto.

  • Form destination checker

    Every form, button and link on a page with the destination it resolves to, flagging off-site and insecure submits.

  • Agent legibility check

    Interactive elements an agent or screen reader cannot name: unlabeled inputs, icon-only buttons, clickable divs.

Compliance

  • XRechnung and ZUGFeRD validator

    Validate an XRechnung XML or a ZUGFeRD/Factur-X PDF with the KoSIT rules in memory and read the invoice.

  • Cancellation button check

    Whether a cancellation button is reachable from a start page, how it is labelled and where it leads; observations only.

Identity

  • TOTP generator

    Live codes from a TOTP secret or otpauth URL, with countdown and clock drift, computed in your browser.

How these tools work

The same code as the product

The cron semantics, the effect gates, the audit verifier and the perception layer are the product's own TypeScript, bundled for the page. A tool here behaves the way a session does.

A real browser in the EU

Tools that scan a URL open an ordinary metered session of a dedicated organisation on EU hardware, capped per visitor and per day. Nothing about them is special-cased.

Observations, not verdicts

A report says what the browser found: a label, a destination, a cookie, a rule id. Whether that satisfies a law or a policy is a judgement the tools do not make.

Nothing stored

What you enter is processed for one response and discarded. A usage journal with timestamps and sizes, described in the privacy policy, is all that remains.

Do the same inside your own session

Five browser hours, no card. Every scan on this page is one API call on a session you control, with a login where you need one.

  • AI Crawler Checker: robots.txt and llms.txt for GPTBot and Co.

    Enter a URL and see what robots.txt allows GPTBot, ClaudeBot, Google-Extended and PerplexityBot, whether an llms.txt exists and if it follows the spec.

  • Agent Legibility Check: Controls Without Names, Icon-Only Buttons

    Scan a URL and list interactive elements an agent or screen reader cannot name: unlabeled inputs, icon-only buttons, clickable divs without a role.

  • Audit Log Verifier: Check a Hash Chain and Seal in Your Browser

    Paste a Browserberg action-log export and verify the hash chain and the signed seal locally with WebCrypto. Nothing leaves your browser; the verifier is Apache-2.0.

  • Cancellation Button Check for German Sites (§ 312k BGB)

    Scan a shop or subscription site in a real browser and see whether a cancellation button is reachable from the start page, how it is labelled and where it leads.

  • Cookie Checker: CMP, Reject Path, Cookies Before Consent

    Scan any URL in a real EU-hosted browser: which consent tool runs, whether Reject all is one click away, and which cookies and third parties load before you choose.

  • Cron Expression Generator with Time Zones and DST

    Build a cron expression, pick an IANA time zone and see the next ten runs. Shows what happens on the nights the clocks change in Europe/Berlin.

  • Effect Classifier: Read, Submit, Payment or Destructive?

    Paste a button label, link text or element HTML and see how Browserberg's effect gates classify it before an agent may click, with the German phrase that matched.

  • Extract Text from a Website: URL to Text or Markdown

    Paste a page link and get its content as clean text or Markdown, with an estimated token count for LLM context. Runs on an EU server; nothing is stored.

  • Form Destination Checker: Where Does This Page Submit Data?

    Scan a URL in a real browser and list every form, button and link with the destination it actually resolves to, flagging off-site posts and insecure submits.

  • HTML to Markdown Converter with Tables and Token Count

    Paste HTML or drop a file and get clean Markdown with headings, lists, links and GFM tables, plus an estimated token count. Converts in your browser, no upload.

  • JSON Schema Generator for Structured Web Extraction

    Paste example JSON or describe fields and get a JSON Schema you can hand to an extraction call. Validates the schema and shows the matching extract request.

  • Product Data Extractor: Price, Availability and SKU from a URL

    Paste a product page URL and get name, price, currency, availability and identifiers as JSON, extracted by an EU-hosted model from a real browser view.

  • TOTP Generator for Testing 2FA Logins (Runs in Your Browser)

    Paste a TOTP secret or otpauth URL and get live codes with countdown and clock drift shown. Computed with WebCrypto in your browser; the secret is never sent.

  • URL Extractor: Get All Links from a Web Page or Sitemap

    Enter a URL and list every link on the page and every URL its sitemap declares, grouped by same-site and external, filterable, exported as CSV or JSON.

  • Website Screenshot API: Capture Any URL from an EU Browser

    Enter a URL and get a full-page or viewport screenshot from a real browser hosted in the EU, cookie banner rejected first. The same call is available as an API.

  • What the AI Agent Sees: Page Tree and Token Count for Any URL

    Load a URL in a real browser and see the tree an agent reads: roles, names, clickability with reasons, and the token cost at three fidelities beside a screenshot.

  • XPath Tester for HTML with Shadow DOM Support

    Paste HTML, write an XPath and see every match highlighted in real time. Handles shadow roots the way Browserberg agents address elements, entirely in your browser.

  • XRechnung and ZUGFeRD Validator with Readable Invoice View

    Upload an XRechnung XML or a ZUGFeRD/Factur-X PDF and validate it with the KoSIT rules in memory on an EU server. See findings by rule id and a readable rendering.
