Carbone vs DocuGenerate

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.

DocuGenerate creates PDF documents by filling Word-style templates with values from JSON or spreadsheet data. Templates can be uploaded as DOCX, DOC, ODT, TXT or SQL files, and listed data formats include JSON, XLSX, XLS, ODS and CSV. Merge tags can place images, tables, lists, conditional content and QR codes into a document. A REST API is available on every plan, including Free, alongside integrations such as Zapier, Make, n8n and Pipedream, plus connectors or plugins for Bubble, Coda, Power Apps, Xano and Backendless. Usage counts generated documents rather than pages, so a 100-page report counts as one document. The Free plan is free and includes 20 documents per month, two templates, API and integrations access, single-document generation and one concurrent document. Plus is $19 a month and includes 500 documents monthly; additional documents cost $0.04 each. Generated files stay stored until deleted, while data used to generate them is described as transient and not stored. Listed processing and storage regions include the United States, European Union, United Kingdom and Australia.
