Retro Rabbit

Retro Rabbit — pros
- + Genuine Slack-first workflow — notes get captured in Slack throughout the sprint, not just at retro time
- + Reduces recency bias by collecting feedback continuously instead of in a 5-minute silent write
- + Simple, opinionated UX with drag-and-drop grouping and dot voting
- + CarrotIQ covers grouping, action-item suggestions and retro summaries on the $40/team/mo Pro AI plan
- + Flat per-team pricing with unlimited users, and CSV/XLSX/PDF export on every tier including Starter
Retro Rabbit — cons
- − Slack is the only chat/issue-tracker integration — no Jira, Teams, Confluence, GitHub, Linear or Azure DevOps
- − No health checks, team radars or longitudinal trend reporting
- − No org-level dashboards, cross-team rollups or action kanban
- − No public API, webhooks or MCP server — data leaves only as a file export
- − Enterprise controls are thin: SSO is Enterprise-tier only, no SCIM, no audit logs, and the privacy policy carries no GDPR or CCPA commitments
RetroTool — pros
- + Genuinely free anonymous retros with no account required
- + Three-click setup — unique URL, share, run
- + Zero-knowledge encryption with custom passwords on Company plan
- + Per-team flat pricing ($10 or $20/team/mo, 15%+ off annually) with <em>unlimited members per team</em>, not per-seat
RetroTool — cons
- − <strong>Apparently dormant</strong>: blog stopped in March 2022, no changelog or release notes, legal docs unchanged since August 2020
- − No native integrations with Jira, Slack, Teams or any agile-stack tool
- − No AI features (clustering, summary, action extraction, sentiment)
- − No health checks, recurring retros, or cross-team reporting
- − Most templates, image cards, named participants, private invite-only boards and zero-knowledge encryption are all behind paid tiers
- − Not SOC 2; no SSO/SCIM/audit logs for enterprise buyers
