PSPDFKit Alternative
PSPDFKit (now Nutrient) is a powerful SDK with 17+ annotation types, real-time collaboration, and native mobile SDKs. It's a strong choice for teams that need advanced document capabilities. The recent rebrand to Nutrient has split their documentation and package names, which can be confusing. For server-side features like BYOS, PSPDFKit requires Document Engine - a separate backend component you host and maintain. SimplePDF is a finished product: one iframe, transparent pricing, no server infrastructure.
What you get with SimplePDF
No Document Engine needed
PSPDFKit requires Document Engine for BYOS, collaboration, and server-side processing. SimplePDF does BYOS (S3 & Azure) with zero server components.
One iframe, ready to go
No npm install, no configuration files, no license keys. One iframe tag and your users have a full PDF editor.
Transparent pricing from $99/mo
PSPDFKit uses quote-based pricing. SimplePDF starts at $99/mo with no annual commitments. You see the price before you talk to sales.
Client-side by default
Documents are processed entirely in the browser. No server roundtrip, no data exposure, HIPAA-friendly by architecture.
