Ceremonies vs ScatterSpoke

Ceremonies is an open-source toolkit for agile estimation and retrospective sessions, offered as a web service or for self-hosting. Estimation rooms use a Modified Fibonacci deck with a coffee-cup choice; votes remain hidden until reveal, results can be sent to Jira, and sessions synchronize through WebSockets without page refreshes. Earlier estimation rounds can be copied into a Slack summary. Retrospectives use Happy, Sad, and Confused cards, anonymous writing, enforced phases, and action items that continue into the next retrospective. Participants join through a link or room code without creating accounts. The source is MIT-licensed. The hosted service is operated by Shadman Rahman. Its Free plan costs nothing and allows one team, five members, and ten sessions per month. The privacy policy says user data is not sold, used for ads, or used to train AI models.

ScatterSpoke helps teams collect feedback and decide what to improve through surveys, retrospectives and Ask. Its AI-assisted retrospectives produce summaries, takeaways and action items in a format teams can share. Teams can choose from a library of more than 20 classic retrospective formats or make custom ones. Asynchronous retrospectives automate feedback collection, and integrations with Jira, Slack and Microsoft Teams connect it with team workflows. In Microsoft Teams, users can create or pin retrospectives in a team space. ScatterSpoke says its AI is built and hosted in-house, and customer data is not shared with major AI providers or used to train other large language models. The free plan includes one seat, unlimited static surveys and responses, 10 one-time Agent Surveys, 50 one-time Ask credits, basic signal detection and MCP access. Pro costs $29 a month per seat for up to five seats; Business costs $149 a month and includes five seats. ScatterSpoke offers 45-day trials and can discuss custom trials through a 30-minute call.
