EZdoc vs WeasyPrint Hosted product vs. self-hosted library
WeasyPrint is a free, open-source Python library that renders HTML and CSS to PDF — you install it, host it, and maintain it. EZdoc is a hosted service — describe a document or upload data, and a finished PDF comes back. No servers, no C-library dependencies, no rendering pipeline to own.
A hosted service vs. a rendering library you run yourself
WeasyPrint is a well-regarded open-source project — 9,200+ GitHub stars, roughly 10 million monthly downloads — that converts HTML and CSS into PDF using its own Python-based layout engine. It supports CSS paged media, flexbox, grid, multi-column layouts, page headers and footers, barcodes, and PDF forms. It is the right tool for a Python team that wants pixel-perfect control over rendering, has the infrastructure to host it, and is willing to write and maintain the HTML/CSS templates that feed it. None of that is a criticism — it is the deliberate scope of a focused rendering library.
EZdoc is a hosted alternative for teams that would rather not own that stack. Describe the document you need — an invoice, a certificate batch, a vendor proposal — and AI generates the content, structure, and formatting in about 30 seconds. For bulk work, upload a CSV and EZdoc produces one personalized PDF per row. For programmatic workflows, the REST API is available on all paid plans and returns finished documents. No servers to provision, no C-library dependencies to manage, no HTML/CSS templates to author and maintain. If the question is "do I want to run a PDF rendering engine, or call an API that gives me the finished document?" — EZdoc answers the second case.
EZdoc vs WeasyPrint — a plain-language comparison
WeasyPrint and EZdoc are not the same category of product. WeasyPrint is an open-source Python library you self-host; EZdoc is a hosted service you call. This page is for teams weighing "run it ourselves" against "call an API" — not for teams comparing two SaaS products feature by feature.
What WeasyPrint does
WeasyPrint converts HTML and CSS into PDF using a custom Python layout engine (not WebKit or Gecko). It supports CSS paged media, flexbox, grid, multi-column, page breaks, headers, footers, barcode generation, and limited PDF form rendering. The CLI is simple: weasyprint input.html output.pdf. A Python API is also available for programmatic integration. It is BSD-licensed, free to use, and well-maintained — v68.1 shipped in February 2026, and the project has over 9,200 GitHub stars and roughly 10 million monthly downloads.
WeasyPrint does not execute JavaScript, which rules out rendering React components, Chart.js visualizations, or any DOM that requires a live browser. It has no template library — you write all the HTML and CSS yourself. It has no web UI, no AI generator, no CSV batch mode, and no REST API. These are not omissions; they are the intentional scope of a rendering library.
What WeasyPrint costs in practice
The license is free. The setup is not trivial: WeasyPrint requires Python ≥3.10, Pango ≥1.44, Cairo ≥1.15.4, GDK-PixBuf, and libffi installed at the system level — not pip packages, but OS-level C libraries. On macOS this means Homebrew; on Linux it is distro packages; on Windows it requires MSYS2 and additional configuration steps. Docker images are available but are community-maintained, not official.
Running it at scale adds server provisioning, monitoring, and capacity planning. And ongoing security maintenance falls on the operator: CVE-2025-68616, an SSRF protection bypass via HTTP redirect, was disclosed in January 2026 and patched in v68.0. Staying current on security advisories and applying patches is part of the operational cost of any self-hosted library.
For North American teams looking for professional consulting support, CourtBouillon (the maintainer) explicitly excludes Canada and the US from its paid support packages. Community support via GitHub issues is available, but professional SLA-backed help is not.
What EZdoc does differently
EZdoc generates the document for you — content, structure, and formatting — from a description in about 30 seconds. No HTML to write, no CSS print stylesheet to debug, no server to provision. For batch workflows, upload a CSV and EZdoc produces one personalized PDF per row. For programmatic access, the REST API is available on all paid plans and returns finished documents via sync response or webhook.
EZdoc's 171+ templates are ready-to-use starting points for common document types — invoices, certificates, proposals, contracts, reports — with data fields pre-wired for CSV or API fill. You describe the document or pick a template; EZdoc generates it. Infrastructure, rendering, and security maintenance are EZdoc's responsibility.
When to choose WeasyPrint
WeasyPrint is the right choice if your team is comfortable with Python, has the engineering capacity to install and maintain system dependencies, can write and maintain HTML/CSS templates, and wants pixel-level control over the rendering output. It is a capable, actively maintained library, and "free to license" is a genuine advantage if you already have the infrastructure and templates in place.
When to choose EZdoc
EZdoc is the right choice if your team would rather not own a rendering pipeline. If you want a document without writing the HTML first, if you need non-developers to generate documents without code, if you need CSV batch generation without custom scripting, or if you want a REST API that returns finished PDFs rather than one that expects finished HTML — EZdoc covers those cases. The tradeoff is on-plan pricing instead of zero license cost; the benefit is no infrastructure, no templates, and no security patches to apply yourself.

Questions, answered plainly
Is WeasyPrint free?
The library itself is free under a BSD-3-Clause license — no subscription, no usage fees. The total cost of using it includes engineering time to install system dependencies (Pango, Cairo, GDK-PixBuf), write HTML/CSS templates for every document type, provision and scale servers, and keep up with security patches. That is real cost, even if the license price is zero. EZdoc's costs are on-plan — infrastructure, rendering, and security maintenance are included.
Why would I use EZdoc instead of WeasyPrint if WeasyPrint is free?
If your team is comfortable with Python, has the infrastructure to self-host, and wants pixel-level control over print CSS, WeasyPrint is a solid choice. If your team would rather describe a document and get a finished PDF without writing templates, running servers, or patching vulnerabilities, EZdoc handles that in about 30 seconds. The comparison is not about price — it is about whether you want to own a rendering pipeline.
Does WeasyPrint have an AI generator or template library?
No. WeasyPrint is a rendering library — it converts HTML and CSS you provide into PDF. It has no AI generation, no template library, no web UI, no CSV batch feature, and no REST API. Those capabilities are outside the scope of the library by design. If you need them, you build them yourself on top of WeasyPrint, or you use a hosted service like EZdoc.
What are the system requirements for WeasyPrint?
WeasyPrint requires Python ≥3.10, Pango ≥1.44, Cairo ≥1.15.4, GDK-PixBuf, and libffi — all installed as system-level dependencies. On macOS this means Homebrew; on Windows it requires MSYS2 plus additional steps. Community-maintained Docker images are available. EZdoc requires a browser and a signup.
What was CVE-2025-68616?
CVE-2025-68616 was an SSRF (Server-Side Request Forgery) protection bypass via HTTP redirect, affecting WeasyPrint before version 68.0. It was patched in January 2026. It is a useful illustration of the security maintenance burden that falls on anyone running a self-hosted library — patching is your responsibility, not the library's maintainer's. EZdoc handles its own infrastructure security.
