Cassiopeia Documentation

Cassiopeia is a stateless SaaS Microservice which provides a RESTful API for generating PDFs based on several input formats. It is designed to be used as a microservice in a larger system, and is built to be highly scalable and fault-tolerant.

The goal is to be very developer-friendly and easy to integrate 🥰

Features

• PDF Generation: Generate PDFs from ODT, DOCX, HTML, Markdown, plain text and many more.
• Merging: Merge multiple documents into a single document.
• Variables / Templates: Use variables in your documents to generate dynamic content.
• Fast and Reliable: Built to be highly scalable and fault-tolerant.
• Simple API: Easy to use and integrate into your system.

There are a lot more features planned for the future. For example:

• Support for HTML templates with styling
• Predefined templates
• Save templates in Cassiopeia
• AI generated templates
• Support for many additional formats like RTF, PPTX, XLSX, etc.
• Many more!

Take a look on the GitLab Board to see what is planned.
