What is planning poker?
Planning poker — also known as scrum poker — is a consensus-based estimation technique widely used in agile software development. Instead of one person guessing how much effort a task takes, the whole team estimates together. Each member privately selects a card representing their estimate (often a Fibonacci number of story points), and everyone reveals at the same time. Poker Sizing is a free, open-source tool that brings this planning poker ritual online.
The reveal is the interesting part: when estimates differ, the highest and lowest voters explain their reasoning. That short conversation surfaces hidden complexity, misunderstood requirements and edge cases — then the team re-votes until it lands on a shared number. The result is a more accurate estimate and a shared understanding of the work, not just a figure on a ticket.
This tool brings that ritual online for remote and hybrid teams: fast, distraction-free, and free to use.
