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.

Leadnics's answer

When our team attended major trade shows like GITEX (Dubai) and the Canton Fair (China), we were buzzing with excitement, so many leads, so many conversations, and so many opportunities! But once we got back, reality hit: the details were all over the place. We had stacks of business cards but couldn't remember who said what, and worst of all, we completely missed some crucial follow-ups.

That’s when our CTO had a game-changing idea, Leadnics. Inspired by this real pain point, he teamed up with our brilliant development team and built Leadnics from the ground up, designed to capture leads smartly, track conversations, and never let an opportunity slip through the cracks again.

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.

Leadnics's answer

Leadnics is built for professionals attending trade shows, expos, and conferences, especially those working in roles like sales, marketing, business development, or event management. Whether you're collecting leads at a booth or networking on the go, Leadnics helps you capture every conversation, track details effortlessly, and follow up without missing a beat. It's the perfect tool for anyone who wants to turn event connections into real business opportunities.

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.

Leadnics's answer

We have used FlutterFlow, Flutter and Firebase to build Leadnics.

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.

Leadnics's answer

Leadnics a smart lead capture tool built specifically for trade shows, expos, and conferences. It helps you collect leads on the spot with full context, notes, tags, voice memos, business card scans and then seamlessly syncs with your existing CRM.

It works offline, has zero learning curve, and ensures you never miss a follow-up again. Lightweight, event-focused, and built to plug into your workflow, not replace it. That’s what makes Leadnics truly 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.

Leadnics's answer

Leadnics is a dedicated lead capture tool, built for teams attending trade shows, expos, and conferences. It helps you instantly collect leads, record conversations, add context (notes, tags, voice memos, card scans), and then syncs all that data to your existing CRM like, HubSpot, Zoho, Salesforce, and more.

You get the best of both worlds: 1) A fast, mobile-first tool made for events 2) No disruption to your current CRM setup 3) Zero learning curve 4) Works offline and syncs when you’re back online 5) Ensures follow-ups never fall through the cracks

In short, choose Leadnics if you want to supercharge your event lead capture without replacing the systems you already use.

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.
