Access, plans, and limitations
Trello works in a browser or through mobile apps and requires an internet connection. The free plan has feature limits, and advanced capabilities require a subscription.
Trello is commonly used by small and mid-sized businesses, startups, and freelancers for task tracking, project delivery, and sprint planning. Keep in mind that boards can become cluttered when managing a very large number of tasks, offline functionality is limited, and some features aren’t available on the free plan.
