Checkvist vs CrossLine

Checkvist is a keyboard-first outliner and online task manager for people who organize work and ideas in lists. Its lists support deep hierarchy, keyboard shortcuts, Markdown, code, tables, bulk operations, sorting and backlinks. Tasks can carry tags, due dates, notes, assignees, file attachments, priorities and progress counters. Lists can be shared privately or publicly with read-only or write access, password protection, expiration times and task assignment. Integrations include Zapier, Dropbox, Google Calendar sync, Jira, YouTrack, Slack, browser extensions and an Open API. Its mobile experience is a progressive web app for iOS and Android that syncs and works offline; the Web Clipper can collect tasks, bookmarks and notes from web pages and services including Gmail, Zendesk, Jira and GitHub. The free plan includes unlimited hierarchical lists and sharing, Markdown, due dates, tags, mobile offline use, browser extensions and Open API. PRO costs $3.90 per person per month, billed at $39 per year, and adds features such as task assignment, repeating tasks, Google Calendar synchronization, 2 GB of file storage and MCP access. A 14-day PRO trial is available without a credit card.

CrossLine is a free, open-source outliner for Windows, Linux, and macOS. It arranges text as parent, child, and subtopic nodes that can be collapsed or expanded, and supports cross-links and Ted Nelson’s transclusion concept. CrossLine also works as a full-text database with a built-in search engine; Lucene can be added as an optional alternative when building the application. Navigation includes search, history, and back/forward controls, with backlinks supported. HTML and CLDX are listed export formats. Precompiled downloads cover Windows and Linux in x86 and x64 versions, plus Mac x64 and M1. The compressed executable can be unpacked and run without installation or special privileges. The README says the Windows build runs on Windows 7 without a separate Microsoft runtime. On Mac, startup requires the context menu’s open command. The project links to a demo repository, provides source-build instructions using LeanQt, and directs support questions to GitHub issues or email. Licenses listed are GPL-2.0 and GPL-3.0.
