Feature-rich, but expect complex setup.
We recognize ClickUp’s ambitious goal to be an all-in-one workspace, offering impressive versatility and an extensive feature set that streamlines project management. While this comprehensive nature is powerful, we found numerous external reports regarding recurring system bugs, slow performance, and extremely poor customer service experiences. Overall, we see that ClickUp is highly flexible for complex business workflows, but teams must be ready for a steep learning curve and potential challenges with reliability and support responsiveness.

Backlog by Nulab Inc offers plans from $0 to $210 per month. You pay a fixed price regardless of how many users join. This makes budgeting simple as your team grows.
