See how PDFluent compares to Nutrient (formerly PSPDFKit) and Apryse (formerly PDFTron) in features, performance, and pricing.
In-depth comparisons with feature tables, benchmarks, and honest assessments.
Java/.NET library. Mature, AGPL available. No PDF rendering, no FormCalc, no WASM.
C++ SDK with real XFA support. 330M+ users. No WASM, mobile only, contact-sales pricing.
JavaScript library for PDF creation. MIT licensed, browser and Node. Not aimed at reading or manipulation.
Best-in-class mobile SDKs. No XFA whatsoever. Pricing from ~€5K/user/year.
Pure Rust implementation with no runtime to start first, unlike a JVM.
Per-developer, not per-API-call. Perpetual licences from €699 (pay once) — published on the website, self-serve evaluation included.
Only pure-Rust XFA engine with full FormCalc support. Competitors lack this entirely.
2.5MB WASM bundle runs PDF processing entirely in the browser. True client-side processing.
Switching from Nutrient or Apryse? We make it easy.
Step-by-step guides for migrating from iText and PDFBox, including API mapping and code examples. PDFluent's open() / save() model maps cleanly from most library-style APIs.
Enterprise customers get free migration support — code review, architecture guidance, and a dedicated channel for questions during the transition.
PDFluent has no runtime to initialise, where a Java-based SDK starts a JVM first. For high-throughput pipelines this translates directly to lower infrastructure costs and faster response times.
Per-product pricing means your licence cost doesn't scale with team size. Add developers freely — the price stays the same until you ship a new product.
