Features and specs

What each product offers, as listed by its team.

Briar 5 features
DynamicDocumentAPI 0 features
  • Privacy-focused
    Briar prioritizes user privacy by encrypting all messages end-to-end, ensuring that only the intended recipients can read the content.
  • Decentralized
    The app operates in a decentralized manner, meaning it doesn't rely on a central server, which reduces the risk of censorship and server-based attacks.
  • Peer-to-peer Communication
    Briar uses peer-to-peer communication methods, including Bluetooth, Wi-Fi, and the internet, enabling connectivity even without a central network or in environments with internet censorship.
  • Open-source
    Briar is open-source software, allowing anyone to inspect, modify, and contribute to its codebase, which helps with transparency and trust in the platform.
  • Offline Messaging
    Briar supports offline messaging via Bluetooth and Wi-Fi direct, which is particularly useful in regions with limited internet access.

Possible disadvantages

  • Limited User Base
    Due to its niche focus on privacy and security, Briar may have a smaller user base compared to more mainstream messaging apps, potentially limiting its network effects.
  • Resource Intensive
    The app can be resource-intensive, consuming more battery and data than traditional messaging apps due to its encryption and peer-to-peer communication methods.
  • Lack of Features
    Briar may lack some of the features found in popular messaging apps, such as media-rich messages, stickers, or integrated services, which might not appeal to all users.
  • Learning Curve
    New users may find the app less intuitive and harder to use compared to mainstream messaging apps, potentially creating a barrier to entry.
  • Android-only
    As of now, Briar is limited to Android devices, which excludes users on other platforms like iOS and may restrict its overall user adoption.

Questions & Answers

As answered by people managing Briar 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.
