Basecamp has been arguing the same position for two decades: most teams do not need more project management features, they need fewer places to look. Each project gets a message board, a to do list, a schedule, a document and file store, a group chat and automatic check in questions. That is the whole product, and the restraint is the point.
Who this is right for
Teams whose real problem is communication rather than scheduling. Agencies working with clients, small product teams, nonprofits, and any group that tried a heavyweight tool and watched it decay into an out of date task list nobody trusted.
Client access is handled better here than almost anywhere. You can loop clients into specific threads while keeping internal discussion private, without buying them seats or explaining a permissions model.
The pricing is the other argument
Pro is 15 dollars per user per month. Pro Unlimited is 299 dollars a month billed annually for unlimited users and projects, with five terabytes of storage. For a team of forty that flat rate is dramatically cheaper than per seat competitors, and it removes the recurring conversation about whether adding someone is worth the licence.
There is also a genuinely free plan covering one project and up to twenty users, which is enough to evaluate it honestly.
Where it frustrates people
There are no dependencies, no Gantt chart and no critical path. If you are running construction schedules or anything where task B genuinely cannot start until task A finishes, this is the wrong tool and no amount of goodwill fixes that.
Reporting is minimal. There is no resource management, no time tracking without a third party add on, and cross project visibility is thin. Teams that grew into needing portfolio reporting are the ones who leave, and they generally leave respecting the product rather than resenting it.
