ThreeKit VS DynamicDocumentAPI

ThreeKit's answer

Threekit primarily serves manufacturers selling complex, configurable products in B2B markets. Its audience includes sales teams, dealer networks, and end customers in industries such as AV equipment, building materials, doors and windows, furniture, heavy equipment, medical devices, and industrial automation. These users need to configure products with many options, generate accurate quotes quickly, and collaborate across channels — whether through websites, mobile devices, tablets, or internal sales tools.

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.

ThreeKit's answer

Threekit was built by the same team behind BigMachines (Oracle CPQ) and Steelbrick (Salesforce CPQ), bringing deep enterprise CPQ expertise. Unlike traditional CPQ systems focused on order processing, Threekit addresses the front-end sales handoff with an AI-first approach. It accepts any input format including voice, photos, and RFPs, deploys in 90 days without migration, and runs alongside existing systems rather than replacing them. It delivers governed AI recommendations with no hallucinations or competitor mentions and is ISO 27001 certified.

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.

ThreeKit's answer

Threekit offers an AI-first approach to quoting that accepts any input format — voice memos, photos, RFPs, specs, or natural language — and returns a valid configured quote in seconds rather than hours or days. It deploys in 90 days alongside existing CPQ, ERP, and commerce systems without requiring migration or replacement. The platform enforces complex product rules to ensure only valid builds are produced, provides real-time 3D visualization and augmented reality, and delivers governed AI recommendations with no hallucinations or cross-customer data sharing. It was built by the team that created BigMachines (Oracle CPQ) and Steelbrick (Salesforce CPQ), combining deep enterprise CPQ expertise with a modern AI-native architecture.

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.

ThreeKit's answer

Threekit was incorporated in July 2018 in the United States. It was built by a team with deep CPQ experience, including the builders of BigMachines (which became Oracle CPQ) and SteelBrick (which became Salesforce CPQ). The company is led by CEO Matt Gorniak and has raised through Series B funding. It has grown to 51–100 employees and is headquartered in Chicago, Illinois.

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.

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.

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.
