PyMuPDF and PDFluent sit on the same AGPL-or-commercial license. The difference is reach: PyMuPDF ships Python only, PDFluent runs one Rust core across Rust, Python, Node.js, .NET, Java, and WebAssembly.
PyMuPDF (the `fitz` module) is the most widely used Python binding to MuPDF, with a large community. It ships for Python only. PDFluent is a native Rust PDF engine with official bindings for Rust, Python, Node.js, .NET, Java, and WebAssembly. SDK 1.1.0 for Python includes a compat layer that follows part of the PyMuPDF API; coverage is partial and behaviour can differ in places; PDFluent is an independent implementation, not PyMuPDF.
use pdfluent::PdfDocument;
fn main() -> pdfluent::Result<()> {
let doc = PdfDocument::open("invoice.pdf")?;
for i in 0..doc.page_count() {
let text = doc.page(i)?.text()?;
println!("--- Page {} ---\n{}", i + 1, text);
}
Ok(())
}import fitz # PyMuPDF
doc = fitz.open("invoice.pdf")
for page in doc:
text = page.get_text()
print(text)

Choose PDFluent if you need the same PDF engine across more than Python — Rust, Node.js, .NET, Java, or the browser via WASM — or if you want native PDF/A validation, XFA forms, and digital signatures without assembling them from separate libraries.
Choose PyMuPDF if your stack is Python-only and you want the most mature, widely documented binding to MuPDF, backed by over a decade of production use and a large community.
PyMuPDF and PDFluent use the same AGPL-or-commercial licensing model, so this isn't a free-vs-paid comparison — it's a question of reach and surface area. If your stack is Python-only and you want the most battle-tested binding to MuPDF, PyMuPDF is a safe, well-documented choice. If you need the same PDF engine across Rust, Python, Node.js, .NET, Java, and the browser via WASM, or native PDF/A validation, XFA forms, and PAdES signing without assembling them from separate libraries, PDFluent covers more ground from one core. SDK 1.1.0 for Python includes a compat layer that follows part of the PyMuPDF API; coverage is partial and behaviour can differ in places. It is an independent implementation, not PyMuPDF.
