TerraFluent
Generate PDF, HTML & DOCX reports from one fluent API
A family of zero-dependency .NET reporting libraries that produce professional documents in three formats from a single, unified fluent API — advanced table layouts with merged cells and repeating headers, native barcodes and QR codes, charts, smart pagination, and streaming async output. Cross-platform on Windows, Linux, macOS, containers, and serverless.
