In their own words
Group-Office
Group-Office is open-source groupware and CRM software for collaboration and business tools. Teams can co-edit documents, schedule meetings, and communicate through chat or video conferencing. Its CRM includes shared address books, newsletters, and support tickets submitted by website or email. Project tools cover task and file tracking, time tracking, reporting, and invoicing project work and time.
Document editing and file management integrate with OnlyOffice, Collabora Online, and Office 365. Finance supports online payments such as Mollie and PayPal, plus ZUGFeRD, XRechnung, and UBL e-invoicing formats. Group-Office synchronizes email, contacts, calendars, notes, and tasks with native apps on iOS, macOS, Android, and Windows using IMAP, Microsoft ActiveSync, CalDAV, CardDAV, and WebDAV. Customers can self-host on their own server or use the hosted service, which the company says is hosted in the Netherlands. The hosted Online plan costs €12.00 per month and includes 5 GB storage per user. Group-Office was founded in 2003 and is based in 's-Hertogenbosch, Netherlands.
VirtualViewer
VirtualViewer is the former name of PrizmDoc for Java, Accusoft’s document-viewing technology for enterprise content management applications. It provides viewing, annotation, redaction, page manipulation, and conversion for formats including PDF, Word, Excel, AFP, DWG, and TIFF. Users can split and merge documents, compare documents, use OCR, and work with thumbnails, bookmarks, and virtual documents assembled from pages across sources. Browser access supports viewing on computers, tablets, and smartphones without client software. Cloud, on-premises, and hybrid deployments are available, with JavaScript and REST APIs, callbacks, a RESTful content handler, and connectors for Alfresco, IBM, and Pegasystems. Accusoft lists controls to disable downloads and a secure-redaction feature. The technical environments include Tomcat, WebSphere, Java 11 or higher, Java-compatible operating systems, and several hosting providers. The documentation says versions 5.12.0 and earlier used the VirtualViewer name; the product is now called PrizmDoc for Java.
