In their own words
Carbone
Carbone merges JSON data into document templates to generate files such as PDF, DOCX, XLSX, and PPTX. Templates can use formats including DOCX, ODT, ODS, XLSX, XML, Markdown, and HTML. Its conversion API handles more than 100 formats and supports LibreOffice, OnlyOffice, and Chromium. API access and bulk generation are listed, with Cloud, On-Premise, Private Cloud, and AWS deployment options. The pricing page lists free Cloud and On-Premise plans, plus a free 30-day trial for self-hosted On-Premise use. Cloud Essential costs $29.00 per month; documents are counted for each 1 MB of injected JSON and images, and additional documents beyond a plan allowance are invoiced separately. Carbone says Cloud stores templates for reuse but does not retain submitted JSON or generated documents beyond what rendering and delivery require. It says it has no access to customer templates, data, or generated documents in on-premise deployments. The service also offers an MCP server and an open-source Carbone Skill for connecting AI assistants and generating templates. Its listed platform options include API, Linux, macOS, self-hosted, web, and Windows.
WeasyPrint
WeasyPrint is free, open-source software for web developers who create PDFs from HTML. Its Python library can turn HTML objects into PDF files with `HTML.write_pdf()`, while the command-line interface offers PDF variants including PDF/A, PDF/UA, and PDF/X. Inputs include HTML, CSS, local files, URLs, file objects, HTML strings, raster images, and SVG. Sample output types include reports, invoices, tickets, books, letters, and posters. WeasyPrint supports Linux, macOS, Windows, and self-hosted deployment; its documentation also describes community-maintained Docker images and an AWS Lambda layer. It can create fillable forms and provides an API. The default HTTP client does not handle cookies or authentication, although a custom URL fetcher can be used. The documentation cautions that untrusted HTML or CSS can create security problems. Version 70.0 requires Python 3.10 or later and Pango 1.44 or later, among other dependencies. The software was created and developed by Kozea; CourtBouillon provides professional support and maintenance.
