Features and specs

What each product offers, as listed by its team.

Orx 6 features
DynamicDocumentAPI 0 features
  • Open-source
    Orx is an open-source game engine, which means it is free to use and can be modified according to user needs. This can be particularly beneficial for small developers or hobbyists who need a cost-effective solution.
  • Cross-platform
    Orx supports multiple platforms, including Windows, macOS, Linux, iOS, and Android. This makes it easier to develop games that can be deployed across different operating systems without significant changes to the codebase.
  • Data-driven configuration
    Orx uses a data-driven approach for configuration, relying heavily on external configuration files in a simple human-readable format. This allows for rapid prototyping and easy adjustments without recompiling the code.
  • Modular and Flexible
    The engine's modular architecture allows developers to use only the components they need, making it highly flexible and lightweight. This can result in better performance and smaller executable sizes.
  • Active Community
    With a dedicated and active community, developers can get support through forums, Discord channels, and extensive documentation, which can be very helpful for troubleshooting and sharing knowledge.
  • Extensive Documentation and Tutorials
    Orx provides comprehensive documentation and tutorials, which can be extremely beneficial for newcomers as well as experienced developers looking to deepen their understanding.

Possible disadvantages

  • Steep Learning Curve
    Despite its extensive documentation, Orx has a steep learning curve, especially for those who are new to game development or are accustomed to more visually-oriented engines like Unity.
  • Limited High-level Tools
    Unlike more mature and commercially-backed engines, Orx lacks some of the high-level tools and features such as a built-in editor or advanced physics functionalities, which can slow down development.
  • Community Size
    Although the community is active, it is relatively small compared to larger engines like Unity or Unreal Engine. This can make it harder to find third-party plugins, assets, or code examples.
  • Performance Overhead
    While it's lightweight and modular, some developers have noted that Orx's abstraction layers can introduce performance overhead, which can be a concern for more resource-intensive games.
  • Lack of Professional Support
    Orx doesn't offer professional support or enterprise solutions. Developers relying on this engine for commercial projects might find the lack of guaranteed, professional support a drawback.

Questions & Answers

As answered by people managing Orx 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.
