/ Product
Document generation as a specialized building block.
From JSON data to pixel-perfect documents with validation, version control, and full control over templates.
/ How does it work?
From data to document.
Receive data
A case system, workflow platform, or application supplies the required data.
Validate
Epistola checks whether the data is complete and usable for the document.
Resolve the template
The right approved template version is selected.
Generate
The document is composed pixel-perfectly according to house style and rules.
Return
The PDF is returned to the system that owns the process.
/ Key capabilities
More than just PDF generation.
Output
Pixel-perfect documents
Consistent PDF output with a fixed house style, layout, and reproducible results.
Authoring
WYSIWYG template management
Document managers design and maintain templates in a visual editor.
Validation
Validation and data contracts
JSON Schema validation helps prevent errors early in the process.
Lifecycle
Template lifecycle
Work with draft, review, publish, archive, and reproducible versions.
Governance
Governance
Support for roles, permissions, environments, OTAP, and controlled rollout.
Operations
Self-hosting
Run Epistola via Docker, Kubernetes, or your own cloud environment.
/ Integrations
Fits into your existing landscape
Epistola does not replace a case system, portal, or workflow platform. It adds document generation as a standalone service.
Works with
Narrow API surface
Send data, select or resolve the template, and receive the generated document through a focused integration contract.
Workflow stays elsewhere
Use Epistola from Valtimo, GZAC, ZGW-oriented systems, or bespoke software without moving orchestration into the document layer.
