Features and specs

What each product offers, as listed by its team.

Merlin 4 features
DynamicDocumentAPI 0 features
  • Julia Language Integration
    Merlin is built using Julia, which is known for high performance and ease of use, particularly in scientific computing and machine learning.
  • Composable Machine Learning Models
    The library allows for easy composition of machine learning models, meaning users can build complex models from simpler, reusable components.
  • Interoperability
    Merlin is designed to work well with other Julia libraries, providing seamless integration with existing Julia ecosystems such as DataFrames.jl and Flux.jl.
  • Community Support
    As an open-source project on GitHub, Merlin benefits from contributions and feedback from the community, which helps in its continuous improvement and troubleshooting.

Possible disadvantages

  • Immature Ecosystem
    Compared to more mature machine learning libraries like TensorFlow or PyTorch, Merlin’s ecosystem is still growing, which may limit its functionality and support in certain areas.
  • Limited Documentation
    While the library is powerful, its documentation may not be as comprehensive as other, more established machine learning libraries, making it harder for new users to get started.
  • Smaller User Base
    Given that Merlin is less well-known, the user base is smaller, which might result in fewer available resources, tutorials, and community-driven support.
  • Potential Stability Issues
    Since Merlin is under active development, it may frequently undergo changes, which could potentially lead to stability issues or breaking changes for its users.

Questions & Answers

As answered by people managing Merlin 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.
