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.
Documint
Documint turns structured data into formatted PDF documents such as proposals, contracts, invoices, reports, certificates, quotes, and shipping labels. Its visual drag-and-drop editor supports variables, functions, loops, conditional logic, and custom branding. Documents can draw data from Airtable, HubSpot, Coda, webhooks, and other listed integrations, while a REST API supports generation from applications. Batch personalisation is available, and each created document counts as one merge; individual documents can contain unlimited pages. Plans include monthly e-signature envelope quotas. Documint runs on the web and through an API. Silver costs $39 a month billed annually and includes a 14-day trial; Gold and Platinum provide larger listed quotas. An on-demand free tier can generate a document from an Airtable button or formula link. Generated PDFs are not stored, sensitive data is retained for no longer than 24 hours, and embedded or on-premise deployment is unavailable.
