Our commitment
Independent research methodology
Our researchers use a mix of verified reviews, independent research, and objective methodologies to bring you selection and ranking information you can trust. While we may earn a referral fee when you visit a provider through our links or speak to an advisor, this has no influence on our research or methodology.
Verified user reviews
GetApp maintains a proprietary database of millions of in-depth, verified user reviews across thousands of products in hundreds of software categories. Our data scientists apply advanced modeling techniques to identify key insights about products based on those reviews. We may also share aggregated ratings and select excerpts from those reviews throughout our site.
Our human moderators verify that reviewers are real people and that reviews are authentic. They use leading tech to analyze text quality and to detect plagiarism and generative AI.
How GetApp ensures transparency
GetApp lists all providers across its website—not just those that pay us—so that users can make informed purchase decisions. GetApp is free for users. Software providers pay us for sponsored profiles to receive web traffic and sales opportunities. Sponsored profiles include a link-out icon that takes users to the provider’s website.

Cassiopeia overview
What is Cassiopeia?
Cassiopeia is a cloud-based, stateless SaaS microservice that exposes a RESTful API for generating PDF documents from a wide range of input formats, including ODT, DOCX, HTML, Markdown, and plain text. Designed for developers and software teams, it supports inline variable replacement across all document types, enabling dynamic, template-based content generation for invoices, reports, offers, serial letters, and custom communications. Multiple documents can be merged into a single PDF output, and API responses are available as either inline base64 or file attachments. A Swagger UI is included for API exploration and integration testing.
Cassiopeia operates on a stateless architecture built for scalability and fault tolerance, making it suitable for integration into microservice-based systems and any application requiring high-volume or automated document creation. No infrastructure setup or self-hosting is required, as the service is fully managed and delivered via the cloud. The platform is GDPR compliant and maintained to high privacy standards, with straightforward API integration that minimizes onboarding overhead for development teams of any size.
