Trello
Trello offers a simple, visual system for organizing team projects, tasks, or other deliverables. Users create lists of to-do items with “cards” where team members can comment, upload files, create checklists, add due dates, and more while moving cards from one stack to another as a project progresses. Pricing: Trello offers basic plans for free; business-level pricing is $10 per month to allow bigger attachments, more boards, more views, and custom fields.
Asana
This is another popular project management platform that allows for mapping out the steps associated with projects and running queries to see how work is progressing. Pricing: A basic plan for individuals or new teams is free; premium-level access is $11 per user, per month for a timeline, custom fields, and more.
Basecamp
Another notable contender focused on overall organization, Basecamp creates project spaces that contain everything related to that effort — all discussions, documents, files, tasks, and key dates and deadlines. There's also a group chat feature. Pricing: A flat $99 monthly for its business-level platform.
