What Ceremonies is
Ceremonies is an open-source toolkit for agile estimation and retrospective sessions, available as a hosted web service or for self-hosting. Estimation rooms use a Modified Fibonacci deck with an optional coffee-cup value; votes stay hidden until reveal, and results can be pushed to Jira. WebSocket updates sync sessions without requiring page refreshes, and past estimation rounds can be copied as Slack summaries. Retrospectives use Happy, Sad, and Confused cards, anonymous writing, and enforced phases. Action items can carry into the next retrospective. Participants join through a room link or code without creating an account. The source code is MIT-licensed, while Docker support is described as planned. The hosted Free plan costs nothing and includes one team, five members, and ten sessions per month. The privacy policy says Ceremonies does not sell user data, run ads, or use user data to train AI models. Account-associated data is deleted within 30 days of account deletion.
