Retro Rabbit
4.4Slack-first retrospectives with async note capture

Echometer — pros
- + 200+ research-grounded health-check items, custom models and automated pulse rotation
- + Longitudinal team radars, heatmaps and workspace dashboards tied to retros
- + EU-only data residency (Open Telekom Cloud, Germany) with GDPR DPA
- + Open actions resurface automatically in the next retro, with email reminders to owners
- + Per-team pricing — €87/mo covers three teams of eight, billed annually
Echometer — cons
- − Thin integrations — Jira and calendar sync only; no Slack, Teams or Confluence
- − No public API or webhooks; export is PDF and Markdown only
- − No SOC 2 — the ISO 27001 certificate covers the datacenter, not Echometer itself
- − Retro-side AI stops at suggesting measures; transcript coaching is a separately-priced 1:1 product
- − No scheduled or recurring retros — you copy a past format and start each session manually
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
