Features and specs

What each product offers, as listed by its team.

Untracker 5 features
DynamicDocumentAPI 0 features
  • Privacy Protection
    Untracker removes tracking parameters from URLs, helping users protect their privacy by preventing advertisers and analytics services from tracking their browsing activity through shared links.
  • Open Source
    The project is fully open source and hosted on GitHub, allowing users to inspect the code, verify its behavior, contribute improvements, and trust that it does what it claims without hidden functionality.
  • Easy to Use
    Untracker integrates with Android's share menu, making it seamless to clean URLs before sharing them. Users can clean tracking parameters with minimal effort as part of their normal sharing workflow.
  • Rule-Based Approach
    The app uses a configurable rules-based system to identify and strip tracking parameters, which makes it flexible and extensible. Users or contributors can add new rules as tracking methods evolve.
  • Lightweight and Focused
    The app has a single, well-defined purpose — removing tracking parameters from URLs. It doesn't try to do too much, keeping it simple, small, and efficient without unnecessary bloat.

Possible disadvantages

  • Android Only
    Untracker is currently available only for Android, meaning users on iOS, desktop, or other platforms cannot benefit from the tool without seeking alternative solutions.
  • Limited Awareness and Adoption
    As a relatively niche GitHub project, Untracker has limited community size and visibility, which may mean slower development, fewer rule updates, and less community support compared to more popular privacy tools.
  • Maintenance Dependency
    Tracking parameters constantly evolve as advertisers create new ones. The effectiveness of Untracker depends on ongoing maintenance and rule updates, and if the project becomes inactive, it could quickly become outdated.
  • May Break Some URLs
    Aggressive removal of URL parameters could occasionally break legitimate functionality of some links, as not all query parameters are tracking-related and some may be necessary for the link to work correctly.
  • Manual Share Step Required
    Users need to actively use the share menu integration to clean URLs, meaning it doesn't automatically clean all URLs system-wide. Links opened directly or copied without using the share flow won't be cleaned.

Questions & Answers

As answered by people managing Untracker 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.
