One fluent API family, four professional solutions. Real PDF files with zero dependencies, paginated printable HTML without a browser engine, real Word documents without Word automation — and server-side SVG charts without a JavaScript charting library.
var report = ReportDocument.Create(PageSize.A4, PageOrientation.Portrait)
.SetMargins(40, 40, 60, 60)
.Header(h => h.AddText("Monthly Sales Report").AlignCenter().Bold())
.Footer(f => f.AddPageNumber("Page {page} of {totalPages}"))
.Content(c =>
{
c.AddHeading("Sales Summary", HeadingLevel.H1);
c.AddTable(t =>
{
t.AddColumns("Product", "Qty", "Revenue");
t.AddRow("Widget A", "120", "$2,400");
t.AddRow("Widget B", "85", "$1,700");
});
c.AddBarcode("INV-2026-0042");
})
.Build();
report.RenderHtmlDocument("monthly-sales.html");All four libraries share the same fluent design, so a team that learns one already knows the others.
Real PDF 1.7 files written by a pure managed C# engine — invoices, reports, and labels with zero dependencies and no native binaries.
dotnet add package TerraFluent.Pdf.Reporting
Paginated, fixed-page HTML reports that view in any browser and print to PDF — PDF-style layout with no PDF engine dependency.
dotnet add package TerraFluent.Html.Reporting
Real .docx files written directly as Open XML — no Word installation,
no COM automation, validated against the Open XML SDK.
dotnet add package TerraFluent.Docx.Reporting
26 chart types rendered as self-contained SVG, entirely server-side — zero JavaScript dependency, zero external NuGet packages.
dotnet add package TerraFluent.Chart.Reporting
No external services, no native binaries — just managed code you can ship anywhere .NET runs.
A4, Letter, Legal, portrait or landscape, custom sizes, precise margins.
Code 128 and QR codes generated in-library across all three libraries — no external services.
ColSpan / RowSpan merged cells, styled headers, row-level pagination.
Repeat on every page with {page} / {totalPages} templates.
Line-level splitting, numbered-list continuation, controlled page breaks.
26 SVG chart types in Chart.Reporting, editable Word charts in DOCX, a vector canvas in PDF, images with wrapping and cropping.
Async file rendering and streaming APIs keep large reports memory-friendly.
Custom elements, renderers, and text-measurement hooks when defaults aren't enough.
No headless browser, no Word COM interop, no native PDF binaries. Pure managed code that deploys cleanly to containers, serverless, and locked-down servers.
DOCX output is validated with the Open XML SDK test suite; HTML output carries unit, pagination, and browser-compatibility tests; the PDF writer runs a full multi-framework test suite across .NET 8, 9, and 10.
Full guides from getting-started to extensibility, a cookbook of recipes, and runnable sample projects in every repository.
Yes. TerraFluent.Pdf.Reporting, TerraFluent.Html.Reporting, TerraFluent.Docx.Reporting, and TerraFluent.Chart.Reporting are all MIT licensed — free for personal, commercial, and open-source projects with no page limits, watermarks, or paid tiers.
Yes. TerraFluent.Pdf.Reporting writes true PDF 1.7 files directly from fluent C# — pure managed code with zero dependencies, including tables, images, barcodes, QR codes, bookmarks, and AES-256 encryption. And TerraFluent.Html.Reporting produces print-ready HTML that saves to PDF from any browser if you prefer an HTML pipeline.
No. TerraFluent.Docx.Reporting writes Open XML packages directly, so it creates real Word documents without Microsoft Office, Word automation, or COM interop — on Windows, Linux, and macOS, including Docker containers and serverless.
Yes. TerraFluent.Chart.Reporting renders 26 chart types as self-contained SVG entirely server-side — Static and Animated modes need no JavaScript at all, and the same SVG drops into a PDF, an HTML report, or a Word document.
iText (iTextSharp) is AGPL licensed, which requires a commercial license for most closed-source use, and QuestPDF's free Community tier has a company-revenue cap. TerraFluent.Pdf.Reporting is plain MIT with zero runtime dependencies — free for any commercial use with a fluent, composable, code-first API.
TerraFluent.Html.Reporting, TerraFluent.Docx.Reporting, and TerraFluent.Chart.Reporting target netstandard2.0 and up, so they run on .NET Framework 4.6.1+, .NET Core 2.0+, and every modern .NET release. TerraFluent.Pdf.Reporting targets .NET 8, .NET 9, and .NET 10.
Yes. All four libraries are pure managed code with no native binaries, no headless browser, and no Office dependency, so they deploy cleanly to Linux, macOS, containers, Azure Functions, AWS Lambda, and locked-down servers.
The Open XML SDK exposes the raw WordprocessingML document model. TerraFluent provides a high-level fluent builder API on top of the same file format — you describe pages, tables, charts, and barcodes in a few chained calls, and the library emits valid Open XML for you.
