DynamicDocumentAPI

No description of Diagrams yet.

Dynamic Document API renders PDFs and images from your own templates, from HTML and CSS or from Markdown. Use it through a REST API, SDKs for Node and Python, Zapier, Make and n8n, or an MCP server for AI agents like Claude and ChatGPT. It also creates validated e-invoices (XRechnung, ZUGFeRD /...

Features and specs

What each product offers, as listed by its team.

D
Diagrams 5 features
DynamicDocumentAPI 0 features
  • Ease of Use
    Diagrams allows users to create cloud system architecture diagrams using a simple Python code. This can be more intuitive for those familiar with programming.
  • Flexibility
    Since Diagrams uses Python, users can harness the power of Python scripts and libraries to generate dynamic diagrams and automate diagram creation.
  • Integration with Popular Cloud Providers
    Diagrams supports a wide range of resources from major cloud providers like AWS, Azure, Google Cloud, and more, making it suitable for modern cloud environments.
  • Open Source
    Being open-source, Diagrams allows for community contributions and improvements, and users can freely utilize and modify the software.
  • Version Control Friendly
    Since diagrams are generated from code, they can be easily managed within version control systems (e.g., git) alongside other project code.

Possible disadvantages

  • Learning Curve
    For non-programmers or those unfamiliar with Python, there might be a learning curve associated with understanding and writing the code needed to generate diagrams.
  • Limited GUI
    Unlike some traditional diagram tools that offer drag-and-drop interfaces, Diagrams relies solely on coding, which might not be as visually intuitive for some users.
  • Dependency on Python
    Users need a working Python environment and must install dependencies to use Diagrams, which can be cumbersome in certain systems or for those not using Python regularly.
  • Complexity for Large Diagrams
    While simple diagrams are straightforward to create, more extensive and complex diagrams can become difficult to manage purely through code.
  • Rendering Limitations
    There might be limitations on the output formats or visual styling compared to specialized diagramming tools that focus heavily on presentation.

Questions & Answers

As answered by people managing Diagrams 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.

  • Create AWS Diagrams with Python and Q in the CLI
    Since I often use Python, I decided to look into Diagrams ( https://diagrams.mingrammer.com) and was impressed by how easily the code was to understand. Started writing diagrams for my Terraform modules, and it worked well. - Source: dev.to / over 1 year ago
  • TIL: Diagrams as Python Code
    When I discovered Mermaid I was thrilled. I recently discovered "Diagrams" an alternative to Mermaid where you express your diagrams using Python code. - Source: dev.to / over 1 year ago

    I'm working on a python library for Vizdom, to be released later this year, but in the mean time, you can use this python library which uses Graphviz under the hood. - https://diagrams.mingrammer.com/. - Source: Hacker News / about 2 years ago
