Features and specs

What each product offers, as listed by its team.

GatsbyJS 5 features
DynamicDocumentAPI 0 features
  • Performance
    GatsbyJS pre-builds your site into static files for fast load times and instantaneous page loads thanks to features like code splitting, PRPL pattern, and Asset Optimization.
  • SEO-Friendly
    GatsbyJS generates static HTML, which helps search engines to index your site more effectively. Additionally, you have fine-grained control over metadata and other SEO optimizations.
  • Rich Plugin Ecosystem
    GatsbyJS boasts an extensive plugin ecosystem that covers a wide array of functionalities such as sourcing data from CMSs, adding analytics, integrating with various APIs, and much more.
  • Strong Community Support
    Gatsby has a robust and active community that provides ample documentation, tutorials, and support to help you get started and troubleshoot issues.
  • Secure and Scalable
    Since Gatsby sites are static, they are inherently more secure against traditional web-based vulnerabilities and can be scaled easily by deploying to a CDN.

Possible disadvantages

  • Build Time
    For larger sites, build times can become noticeably long as Gatsby rebuilds the entire site. This can be a bottleneck for frequent updates.
  • Less Suitable for Dynamic Content
    Since Gatsby generates static pages, it's less suited for applications that require real-time data updates or dynamic content unless they are integrated with client-side JS or third-party services.
  • Initial Setup Complexity
    Getting started with Gatsby can be complex for beginners unfamiliar with React and GraphQL, as it requires knowledge of these technologies.
  • GraphQL Learning Curve
    A significant part of customizing and extending Gatsby sites involves GraphQL queries, which can be a barrier for developers who are not yet familiar with GraphQL.
  • Plugin Quality Variability
    While Gatsby has a rich plugin ecosystem, the quality and maintenance of plugins can vary, requiring developers to vet the plugins they choose to integrate into their projects.

Questions & Answers

As answered by people managing GatsbyJS 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.
