The first thing to say is that the term “Planning Poker®” is a registered trademark of Mountain Goat Software, the Mike Cohn company. This is why this agile planning practice could be sometimes names differently: scrum poker, agile poker, etc. This article presents a list of free and open source planning poker tools and plugins that are also directly available as online tools.
Planning poker is originally a card game used by Scrum teams to estimate effort or relative size of user stories or features when during sprint planning. Team members estimates by playing numbered cards face-down to the table. Then the cards are revealed and the estimates are discussed. Discussion is the main interest of playing planning poker, because some developers will share why they vote differently from the consensus. This can be done with paper cards if the team is collocated, but in the case of a distributed Scrum team, you need to use a software to do it. Using a tool also makes it easier to record and remind previous planning estimations.
There are many open source implementations of the Agile planning poker practice. I have decided to present only those who have also an online website or that are built as a plugin for another application like Slack, Jira, Trello or the Azure Boards. If a good tool is missing from this list, do not hesitate to contact us, and we will add it in a future update.
