Scroll Test 5 features
DynamicDocumentAPI 0 features
  • Simple and Focused Tool
    Scroll Test provides a straightforward, single-purpose tool for testing how far users scroll on a webpage. Its simplicity makes it easy to understand and use without a steep learning curve.
  • Visual Heatmap Results
    The tool generates visual scroll heatmaps that clearly show where users stop scrolling on a page, making it easy to interpret data and identify content placement issues at a glance.
  • Quick Setup
    Setting up a scroll test is relatively fast and uncomplicated. Users can upload a screenshot or URL and start collecting data without extensive technical configuration.
  • Useful for Content Prioritization
    Scroll Test helps designers and marketers understand which content areas get the most visibility, enabling better decisions about where to place important calls-to-action and key information.
  • Free or Low-Cost Option
    Scroll Test offers an accessible entry point for individuals and small teams who need basic scroll-depth analytics without investing in expensive enterprise-level UX research tools.

Possible disadvantages

  • Limited Feature Set
    Compared to comprehensive UX testing platforms like Hotjar or Crazy Egg, Scroll Test is quite limited in scope. It focuses only on scroll behavior and lacks click tracking, session recordings, or A/B testing features.
  • Small or Unclear User Base
    As a niche tool, Scroll Test may have a smaller community and fewer integrations compared to mainstream analytics platforms, which can limit support resources and third-party compatibility.
  • Limited Analytics Depth
    The tool provides basic scroll data but may lack advanced analytics features such as segmentation by device type, traffic source, or user demographics for more granular insights.
  • Potential Sample Size Issues
    Getting statistically significant results may be challenging, especially for lower-traffic sites, as the tool relies on collecting enough participant data to draw meaningful conclusions.
  • Less Actively Maintained
    Being a smaller, niche tool, Scroll Test may not receive frequent updates or new feature additions compared to larger competitors, potentially leading to compatibility issues with modern browsers or websites over time.

Questions & Answers

As answered by people managing Scroll Test and DynamicDocumentAPI.

What makes your product unique?

DynamicDocumentAPI's answer:

It covers the whole path from data to finished document in one API: you design a template in a visual or HTML editor (or send raw HTML, CSS or Markdown), send JSON, and get a PDF or image back. The same service also creates e-invoices (XRechnung, EN 16931, Factur-X / ZUGFeRD) that are validated against the official rules before they are returned, and can embed them in the PDF. Rendering is deterministic: the same template and data always give the same document, laid out by a headless browser, with no AI model generating content. Everything runs in the EU (Germany). It also ships an MCP server, so AI agents like Claude and ChatGPT can render documents directly.

Why should a person choose your product over its competitors?

DynamicDocumentAPI's answer:

Most document APIs do one thing: convert HTML to PDF, or fill templates. Dynamic Document API does both, adds image templates, PDF merging and validated e-invoices, and offers them through a REST API, SDKs for Node and Python, Zapier, Make, n8n and an MCP server for AI agents. Data is processed and stored in the EU only, files come back as signed links that expire, and storing nothing at all is a supported option. Pricing is predictable: one published credit table, the same core features on every paid plan and a spend cap you control. We also publish a render-time benchmark with its method and raw data, so you can check our speed instead of trusting a claim. The free plan includes 50 renders a month without a credit card.

How would you describe the primary audience of your product?

DynamicDocumentAPI's answer:

Developers and product teams whose software has to send documents: invoices after a payment, certificates after a course, reports, labels and statements. Typical users are SaaS companies, marketplaces, e-commerce and learning platforms. A second group are businesses in Germany and the EU that need compliant e-invoices (XRechnung, ZUGFeRD) for the German B2B e-invoicing mandate and public-sector buyers. No-code builders use it through Zapier, Make and n8n, and teams building AI agents use the MCP server.

What's the story behind your product?

DynamicDocumentAPI's answer:

Almost every product eventually needs to produce documents, and most teams end up building their own rendering stack: a headless browser, fonts, page breaks, storage and retries. It works until an invoice splits a table row or a certificate shows the wrong date, and then it becomes a support ticket. We built Dynamic Document API to be that layer for them: templates, rendering and delivery as one service, hosted in Europe, treating pagination, fonts and formatting as engineering problems rather than edge cases. When e-invoicing became mandatory for B2B in Germany, we added validated XRechnung and ZUGFeRD output, and with AI agents producing more paperwork, an MCP server followed.

Which are the primary technologies used for building your product?

DynamicDocumentAPI's answer:

Rendering runs in Rust workers that drive headless Chromium over the DevTools protocol, with MiniJinja for templates. The API and control plane are built with Django and Django REST Framework, with Celery, PostgreSQL, Valkey and NATS JetStream for queues and events, and S3-compatible object storage for files. PDF/A output is checked with veraPDF and e-invoices with the official KoSIT validator. The dashboard and website are built with Next.js. Everything runs on Kubernetes in data centres in Germany.

Who are some of the biggest customers of your product?

DynamicDocumentAPI's answer:

Dynamic Document API is a young product. Our users are mostly developers and small SaaS teams, and we don't name customers without their permission.
