Carbone vs Docmosis
Both turn a template and a JSON payload into a finished document, and neither is an application for the people who write contracts. The split is in how you buy and run them. Carbone meters documents, lets you start free on the cloud or on your own servers, and is made in France. Docmosis sells cloud tiers by users and environments, or a perpetual licence for a self-hosted engine, and its output stops at PDF, Word, ODT and text. Both expect a developer to do the integration work.
Vendors can pay for more visibility on this website, for example a higher place in a ranking or more room on a page. Commercial relationships can also affect which products we feature and how prominently. Every vendor link is marked the same, whatever the arrangement behind it. How that works.
you want a free way to begin, either on the cloud or on your own server, and you generate documents from Word or ODT templates. You also prefer a vendor whose footer says France.
you need a perpetual licence for an engine inside your own network, or a cloud quota with no overage charge. You accept that the output formats stop at PDF, DOCX, ODT and TXT.

Where they differ
Carbone 3 · Docmosis 2 · open 1- 01
Running it inside your own walls
Docmosis Tornado runs on Linux, Windows or Docker, in private data centers or on public cloud such as AWS or Azure, with unlimited generation under a perpetual licence. Carbone lists Cloud, On-Premise, AWS and Docker, and its Community Edition is free and unlimited on your own servers. Our data describes that edition as source-available under Carbone's own licence, which may not be resold as a hosted service. Both keep data in your hands, so this round is level.
Depends on the buyer
- 02
Paying per document or per environment
Carbone cloud plans scale by documents a month: Essential at 29 EUR for 1,000, Essential Plus at 95 EUR for 5,000, up to Advanced Ultra at 595 EUR for 500,000, all excluding VAT, with overage per document. Docmosis cloud tiers scale by users and environments: Professional $49, Business $64 and Enterprise $78 a month, each with a quota of 4,000 or more pages. The Docmosis page says there are no overage charges and no blocking at quota. For spiky volume that matters.

A free start without a sales call
Carbone Cloud Free costs 0 EUR and allows 100 documents a month, 100 templates and 1 parallel render, with 15 days of analytics and no chat support. Its on-premise edition also has a free 30-day trial, and no trial is listed for the paid cloud plans. Docmosis lists no free plan at all. It offers a 30-day cloud trial with no credit card required. A team that wants a permanent sandbox gets more from Carbone.

Perpetual licence versus fixed server price
Docmosis licensed editions are one-off perpetual USD licences: 3,795 for 1 converter and 50 templates, 6,695 for 4 converters and 200 templates, 9,995 for 8 and 500, and 17,145 for unlimited, with 12-month renewals from 1,518 USD. Carbone On-Premise Fit is 1,500 EUR for one server and 12,000 documents, and Unlimited is 2,940 EUR for unlimited servers. Neither charges per user. The Carbone entry price is lower, but renewal terms for it are not shown on the page.

File types the renderer will write
Docmosis writes PDF, DOCX, ODT and TXT, and the site says XLSX and PPTX are not generated. Its cloud uptime target is above 99.9 percent monthly, and the cloud runs on AWS across the US, EU and AU regions. Carbone's site lists no output formats and no uptime target in our data, though templates are ordinary Word or ODT files with tags. On stated formats and a stated uptime figure, Docmosis gives the buyer more to check.

What authors get beyond the API
Carbone ships Carbone Studio, where authors preview templates, and because templates are plain Office files the person who writes the contract can edit them directly. It has no workflow, approvals or template governance. Docmosis is a developer tool with no interface for document authors, no clause library and no approval or negotiation features. Both need a developer to integrate, but Carbone at least puts template editing within reach of a business user.
Edge: Carbone
When neither fits
If you want authors to configure documents and approvals without a developer, neither fits. Docupilot is a no-code route in this category, and Legito suits legal teams who want to own templates themselves.
Carbone or Docmosis: questions
3 answersCan a document engine with no overage fee still run out of room?
The Docmosis pricing page says cloud quota has no overage charges and no blocking at quota, with 4,000 or more pages a month on every tier.
The tiers differ by users and environments instead, from 1 user and 1 environment to 10 users and 4. Carbone instead charges per extra document, from 0.05 EUR on Free down to 0.001 EUR on Advanced Plus and Ultra.
Which one lets a Word user write the template?
Carbone does, since a template is an ordinary Word or ODT file with tags and authors can use Carbone Studio or Word.
Docmosis is described as a developer tool with no interface for document authors. Docmosis names no template editor in the facts we hold, so ask before assuming one.
Where are these vendors based?
Carbone's footer reads Made with love and passion in France, and our data lists France. Docmosis is Docmosis Pty Ltd, and our data lists Australia, though its footer shows no address or country. Neither site names an owner or parent company.
