Avanquest's Web platform is split into two complementary products, built on the same optimized WebAssembly (.wasm) engine, that can be used independently or together.
- UI Component Library — pre-built, customizable, white-label components for in-browser or in-app document experiences: viewing, annotating, form-filling, signing, and reviewing.
- Headless SDK (no UI) — a programmatic engine for generating, modifying, analyzing, and automating documents with no visual interface, suitable for background processing on a user's device or on a Node.js server.
Use the UI library when end users need to see or interact with a document directly in your web application, whether that's a browser, an Electron app, a PWA, a mobile WebView, or even a kiosk. Use the Headless SDK when you need document logic without a visible interface — for example, generating a contract in the background before displaying it with the UI library.
