Carbone vs DocMake

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.

DocMake generates Word (DOCX) and PDF files by merging data into reusable templates. Templates are made in a visual, Word-like editor with blanks, conditional sections, and repeatable content. Users can fill them in the app, share a form link that someone can complete without an account, or send JSON through the REST API. The same template produces native DOCX files and print-accurate PDFs with matching layouts. Existing DOCX files can be imported as editable templates while retaining headings, tables, headers, and footers. AI can draft template content, and templates can be translated into eight languages while keeping their structure and blanks. Team workspaces include shared templates, per-team API keys, custom fonts, and an audit log. The Free plan is an unlimited-time trial with no credit card required; it allows 1,000 documents per month and adds a DocMake footer. Pro costs $29 a month.
