Retrium — Pros
- + Battle-tested five-phase guided facilitation flow
- + Anonymous brainstorming and grouping by design
- + Persistent team-room action plan that carries forward between retros
- + Team Radar covers psychological safety and custom health checks
- + Per-team-room pricing with unlimited users on every plan
Retrium — Cons
- − No free tier; 30-day trial only
- − Integrations are thin beyond Jira Cloud and a <em>still-beta</em> Slack app
- − <strong>No AI features at all</strong> — no summary, clustering, action-item extraction or insights
- − No native Microsoft Teams, Azure DevOps, GitHub, Linear or Confluence integration
- − Public shipping cadence has slowed — no 2025 changelog or product blog activity visible
- − Retro-only scope; no planning poker, kudos, icebreakers or whiteboard
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 (not per-user) pricing can get expensive at scale across many small teams
