Beyond Compare vs Mergely

Beyond Compare compares folders, text files, images, and tables so users can inspect differences and merge changes. Folder comparisons can include recursive subfolders and filters based on modified time, size, filename case, or file content. Text tools provide syntax highlighting, inline editing, and options to ignore whitespace or comments; Pro adds two-way and three-way text merge. Other supported data includes CSV, tab-delimited files, HTML tables, Excel worksheets, binary files, images, and audio tag data. Folder Sync can reconcile data with disks, FTP servers, and zip files, and command-line scripts can run scheduled syncs. Pro also includes secure FTP connections, remote Subversion repositories, and cloud storage options such as WebDAV, Amazon S3, Dropbox, and OneDrive. It runs on Linux, macOS, and Windows. The license is a one-time purchase, with Standard Edition at $35, paid once per user and Pro Edition at $70, paid once per user. Free evaluation is available, but continued use requires a license.

Mergely is a browser-based diff and merge editor plus a JavaScript library for comparing two text documents. It places documents side by side and marks additions, deletions and changes. Differences are computed in the browser with JavaScript, without server calls for the comparison. The maker says imported documents stay in the browser unless saved or shared; saved diffs are public to anyone with the link and can be managed there. Developers can embed the library in web applications through its API. Documentation recommends the React component and describes CDN and webpack use, while the Angular component is out of date. Options include ignoring whitespace, case or accented characters, line numbers, wrapping and sidebars. The API can merge a whole document or a selected change across sides. Firefox, Chrome, Edge and Safari are supported. The open-source release is free under GPL, LGPL and MPL licenses; a Closed Distribution License is available by contacting the maker.
