A side-by-side look at scores, pricing, features and integrations to help you pick the right retrospective tool.

Free planning poker, retrospectives and standups for Scrum teams
Estimioo is a lightweight, browser-based agile-ceremony tool that bundles AI-assisted planning poker, a template-driven sprint retrospective board and async daily standups into one shared workspace. The product's centre of gravity is estimation, but the retro module has grown since launch: the vendor now lists a library of retrospective formats (Start/Stop/Continue, Sailboat, Mad/Sad/Glad, 4Ls, Starfish, Sprint Timeline and more) rather than a single fixed board. It's still a reflection-and-summary tool, not a deep facilitation suite with dot voting, grouping and owned action items.
