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.
GNOME Document Scanner
GNOME Document Scanner makes digital copies of photos and documents on Linux. Scans can be cropped or rotated, printed, exported to PDF or saved as JPEG or PNG images. The app uses the SANE framework to support most existing scanners. With a scanner that has an automatic document feeder, it can scan pages from the feeder; two-sided scanning is available when the scanner supports it. The app can open the user's email program with a scan attached: text scans use PDF attachments, while image scans use JPEG attachments. The latest version is installed from Flathub, whose package is available for x86_64 and aarch64 architectures. Version 50.0 was released on 2026-04-02, and the project is licensed under GPL-3.0. The app is free and listed for Linux desktop use. Users can report issues through the project's GitLab issue tracker and consult the Document Scanner manual.
