mdedit.io VS DynamicDocumentAPI

mdedit.io's answer

mdedit.io combines a distraction-free Markdown editor with professional document production in a single browser app — no account, no install. It is the only open-source browser editor that offers outline navigation for long documents, print-ready PDF export via Paged.js, DOCX export, BibTeX/CSL citations, Mermaid diagrams, KaTeX math, and optional AI assistance together in one tool. Everything runs in the browser and can be fully self-hosted.

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.

mdedit.io's answer

Most Markdown editors are built for quick notes. mdedit.io is built for serious documents: thesis drafts, technical specifications, reports, academic papers. Unlike Typora or Obsidian it runs entirely in the browser with no installation. Unlike StackEdit or Dillinger it produces print-ready PDF output with proper page layout, headers, footers and page numbers. Unlike Notion or Google Docs it requires no account and can be self-hosted under an open-source license (Apache 2.0).

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.

mdedit.io's answer

Students and academic authors writing thesis papers, seminar papers or research articles who want an alternative to LaTeX without giving up document quality. Secondary audiences are developers and technical writers who produce specs, ADRs or reports in Markdown, and privacy-conscious teams or organisations that self-host their own document tooling.

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.

mdedit.io's answer

mdedit.io was built out of frustration with the gap between note-taking Markdown editors and full document production tools. LaTeX produces great output but has a steep learning curve. Word struggles with long structured texts. Browser-based Markdown editors export basic HTML at best. The goal was a tool that feels as simple as a text editor but produces output as clean as a typeset document — directly in the browser, without an account, self-hostable for anyone who needs full control over their data.

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.

mdedit.io's answer

Node.js, Fastify, CodeMirror 6, markdown-it, Paged.js, Mermaid, KaTeX, better-sqlite3, Docker. Runs entirely in the browser on the client side for editing and preview; server handles persistence, collaboration and PDF rendering.

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.

mdedit.io's answer

• mdedit.io is currently in public beta with individual users

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.
