Calco documentation

Everything you need to convert, manage, and integrate document templates at scale. Pick a topic below to get started.

Calco comes two ways. As a subscription on the Unikia platform, it is fully hosted — sign in and start rendering, with no infrastructure to run. As an enterprise product, it is delivered as a private binary or Docker image you run on your own infrastructure (see Self-hosting & deployment). The rendering engine, API, web dashboard, and MCP server are identical in both; only the operational concerns — installation, configuration, storage, and the database — apply to the self-hosted distribution.

Self-hosting & deployment
