In their own words
Dynamic Web TWAIN
Dynamic Web TWAIN is a browser-based document-scanning SDK for web applications that control scanners using TWAIN, WIA, ICA, SANE, and eSCL. Scanning runs locally through the Dynamsoft Web TWAIN Service, and document data is not sent to Dynamsoft servers. Scanned pages can be exported as PDF, TIFF, JPEG, PNG, or BMP, including multi-page PDF and TIFF files. The built-in viewer and editor provide annotation, zoom, deskew, and rotation. Disk caching supports unlimited pages per session, and a 64-bit service mode is available for large data. Supported client systems include Windows 7 or later, macOS 10.15 or later, and Linux distributions for x64, ARM64, or MIPS. Listed browsers include Chrome, Firefox, and Edge on Windows and Linux, and Safari on macOS. The SDK works with React, Vue, Angular, JavaScript, and TypeScript, with server-side compatibility for Node.js, PHP, ASP.NET, Java, and Python. A 30-day trial gives full SDK access without feature restrictions and requires no credit card. Pricing is available on request; there is no free plan. PDF Rasterizer, Barcode Reader, OCR, and Webcam add-ons are licensed separately.
VueScan
VueScan is scanning software for Windows, macOS, and Linux, designed to work with flatbed, document, and film or slide scanners. Its maker says it supports over 8,000 scanners from 42 manufacturers. For flatbed photos, it can detect, crop, and separate multiple images. Document tools include OCR, searchable and multipage PDFs, automatic deskewing, and blank-page removal; 49 OCR languages and batch scanning are listed. Film tools include infrared dust and scratch removal, faded-color restoration, multi-exposure scanning, IT8 calibration, and RAW output. Film and slide scanner support and RAW output require Professional; Standard includes document feeder support and OCR. The trial has no stated time limit, but its scans carry a watermark that cannot later be removed. Monthly plans are $7.46 a month for Standard and $14.96 a month for Professional. One-time editions cost $89.95 as a one-time purchase for Standard and $206.95, paid once for Professional, each including one year of free updates.
