Retro Rabbit — pros
- + Genuine Slack-first workflow — capture notes via /retro during the sprint, not just at retro time
- + Reduces recency bias by collecting feedback continuously, not in a 5-minute silent write
- + Simple, opinionated UX with drag/drop grouping and dot voting
- + CarrotIQ AI handles grouping, action items and summaries on the Pro AI plan
- + Per-team flat pricing scales cleanly for small squads
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
- − Enterprise controls are thin: SSO is Enterprise-tier only, no SCIM, no audit logs, no documented GDPR posture
- − Per-team flat pricing — 3 teams of 8 lands at $90/mo on the Starter tier
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) rather than per-seat
RetroTool — cons
- − <strong>Apparently dormant</strong>: no blog, changelog or release notes; legal docs last updated 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
- − Private invite-only boards and zero-knowledge encryption locked behind paid tiers
- − Not SOC 2; no SSO/SCIM/audit logs for enterprise buyers
