Dynamic Web TWAIN vs ExactScan

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.

ExactScan is a document-scanning application for scanning, sorting, filing, and archiving documents in a paperless office workflow. It supports more than 500 scanner drivers as well as TWAIN and ImageCapture drivers. Built-in processing can detect paper size, correct skew, optimize black-and-white scans, and detect blank pages. Users can create profiles, scan to PDF or other formats, and produce searchable PDFs. ExactScan can act as a TWAIN driver and send image files to third-party applications that do not support TWAIN or ImageCapture. AppleScript support lets users access profiles, set scan options and destinations, and monitor processing status. Pro adds OCR in 26 languages and batch tools including page rotation, PDF appending, 1D barcode recognition, text imprinting, and processing existing files. Enterprise supports scanners rated at 100 pages per minute or higher, PDF/A-1b, and additional barcode formats. It runs on Linux, macOS, and Windows. One-time licenses cost 80.00 EUR for ExactScan, 100.00 EUR for ExactScan Pro, and 250.00 EUR for ExactScan Enterprise. A 14-day trial is available; there is no free plan.
