Estimioo vs Openbook

Estimioo is a web tool for agile teams running planning poker, sprint retrospectives, and asynchronous daily standups. Its optional Claude-powered AI proposes story-point estimates with reasoning and can identify missing acceptance criteria or hidden complexity. Votes stay concealed until simultaneous reveal, with high vote variance flagged. Teams can use Fibonacci, Modified Fibonacci, T-shirt, or Powers of 2 scales. Retrospectives provide more than 45 templates on every plan. Standup rooms organize yesterday’s work, today’s plans, and blockers in date-keyed, timezone-aware updates. Guests join through an invite link or QR code without accounts; only the host signs in. Results and standup summaries can be copied to Slack without a bot. The Team plan adds Jira Cloud through OAuth or an API token, issue previews, and filtered backlog imports; estimate write-back is on the roadmap. AI data is not retained for training, and Privacy Mode removes specified identifiers before submission. The Free plan costs nothing, while Team costs $7 a month.

Openbook is a team workspace organized into organizations, spaces, and rooms, with 21 room types for planning, writing, discussion, and tracking. Its build agent can connect to GitHub and GitLab repositories, make changes, run builds, and open pull requests. Organizations can use platform-run AI models or configure provider keys for OpenAI, Anthropic, DeepSeek, xAI, Google, and Azure OpenAI. Built-in connectors include WordPress, Slack, Figma, Shopify, Stripe, Google Calendar, Cal.com, Calendly, five helpdesks, HubSpot, and Salesforce. Connector writes are disabled by default and require explicit enablement; irreversible third-party actions run only in auto mode. Files can be stored on Openbook, S3-compatible storage, Dropbox, or Microsoft SharePoint/Teams; default server storage is limited to 30MB. A read-only Board API exposes Kanban boards as JSON and supports change webhooks. Free costs nothing and allows up to 10 editing members and 3 spaces; viewers and guests are free. New organizations start with a 14-day Pro trial without a card. Business costs $15 a month. The intended audience includes product managers, founders, small teams, and agencies.
