Reviewers mostly praise Linear for being fast, clean, and easy to adopt, with many saying it feels lighter and less process-heavy than Jira, Asana, or ClickUp while still handling issue tracking, cycles, and team alignment well. Users repeatedly mention strong shortcuts, smooth performance, and useful integrations with Slack, GitHub, and other tools. The main complaints are limited customization, weak support for complex multi-team planning, no real board or swimlane views, single-assignee constraints, and some confusing UI choices around cycles versus active work.
