If GroupDocs licensing is getting in the way, the best alternatives depend on what you’re using it for:

If you need document conversion / viewing / annotations

  • Aspose — very full-featured, but also commercial and can be pricey.
  • Syncfusion DocIO / PDF tools — strong suite, often more flexible licensing.
  • Telerik / DevExpress — good if you’re already in their ecosystem.
  • PSPDFKit — excellent for PDF viewing/editing, especially web/mobile.
  • PDFTron / Apryse — powerful PDF and document SDKs.

If you need PDF-only

  • iText — popular, but licensing is strict for commercial use.
  • PDFsharp / MigraDoc — open source, good for simpler PDF generation.
  • QuestPDF — modern, very nice API for generating PDFs in .NET.
  • wkhtmltopdf / Playwright-based HTML-to-PDF — good if your source is HTML.

If you need document processing in .NET

  • Aspose.Words / Cells / Slides — often the closest replacement for GroupDocs features.
  • GemBox — simpler licensing and solid feature set.
  • IronPDF / IronXL / etc. — convenient, but check licensing carefully.
  • Open XML SDK — free, if you’re mainly working with Office files at a lower level.

If you want open-source / cheaper

  • LibreOffice headless — great for conversion pipelines.
  • Pandoc — excellent for format conversions, especially text-centric docs.
  • Apache POI — Java world, for Office formats.
  • Open XML SDK + third-party libraries — more work, but avoids vendor lock-in.

Practical guidance

If your pain is specifically license cost/complexity, the usual shortlist is:

  1. QuestPDF for PDF generation
  2. GemBox for lightweight Office/PDF needs
  3. Aspose if you need broad file-format coverage
  4. LibreOffice headless for batch conversions
  5. Apryse/PDFTron if PDF is the core product

If you want, I can recommend the best replacement based on:

  • your platform (.NET, Java, Node, Python)
  • file types (PDF, DOCX, XLSX, PPTX, images)
  • features needed (convert, merge, sign, edit, annotate, OCR)
  • budget / open-source preference
