Retro Rabbit
4.4Slack-first retrospectives with async note capture
Retro Rabbit is a Slack-native retrospective tool that lets teams capture notes throughout the sprint from Slack or the web app, then runs the retro on a synced board with drag-and-drop grouping, voting and assignable action items. The CarrotIQ AI layer is gated to the Pro AI plan. No public changelog and no visible feature change since April 2025 — ask for a roadmap before committing.

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
Trune.io — pros
- + EU/Frankfurt data residency and GDPR-first posture — even the AI assistant runs on an EU-hosted function
- + Per-team (not per-seat) pricing: $19/mo covers unlimited members, and the free tier gives 5 full sessions
- + Native two-way Azure DevOps sync — action items out as work items, Done status back in
- + Team radars include the Spotify Squad Health Check plus fully custom radars
- + Exports cards, action items and radar results to Excel, CSV or an emailed PDF
Trune.io — cons
- − No SSO, SCIM, SOC 2, or audit logs — not enterprise-ready
- − The native iOS/Android apps are gone from both app stores, though the site still advertises them as new
- − AI stops at truneGPT, a ChatGPT-4 chat assistant — no clustering, summaries, action extraction, or sentiment analysis
- − Azure DevOps is the only native connector, and it needs the pricier Professional tier; everything else is a single one-way Zapier trigger
- − No recurring retros, async mode, parking lot, or agenda planner; reporting stops at team level with no cross-team rollups
