Echometer
5.6Psychology-backed retros and team health checks for engineering teams
Echometer is a German retrospective, health-check and 1:1 meeting platform built around recurring pulse surveys, structured retros and longitudinal team development tracking. It pitches itself to busy team leads — engineering managers, scrum masters and agile coaches — who want research-grounded question libraries rather than a blank whiteboard.

Retro Rabbit
4.4Slack-first retrospectives with async note capture
Retro Rabbit is a Slack-native retrospective tool: the team drops notes into a Slack channel or the web app all sprint long, then runs the retro on a live synced board with drag-to-group, dot voting, a shared timer and assignable action items that carry over to the next retro. The CarrotIQ AI layer is gated to the $40/team/month Pro AI plan. Four-person vendor, Slack is the only integration, and there is still no public changelog.
Full review →Summary
Echometer scores 5.6 overall and is best for engineering managers and agile coaches who want recurring health-check pulses tied to retros, with EU data residency and a research-flavoured question library. It offers a free tier.
Retro Rabbit scores 4.4 overall and is best for slack-centric agile teams that want retro notes captured continuously through the sprint and a lightweight live or async board — and that don't need Jira, health checks or a procurement checklist. It offers paid plans from $30/team/mo.
Echometer leads on retro toolkit, fun factor, integrations, open platform and enterprise-grade.

Echometer — pros
- + 200+ research-grounded health-check items, custom models and auto-scheduled pulse surveys
- + Longitudinal team radars, heatmaps and a cross-team workspace dashboard tied to retros
- + German-only hosting (Open Telekom Cloud, Magdeburg/Biere) with a GDPR data processing agreement
- + Open actions resurface automatically in the next retro, with owner email reminders and one-click push to Jira
- + Per-team, not per-seat, pricing — €87/mo covers three teams of eight, billed annually
Echometer — cons
- − Beyond Jira, Slack and Teams only get 'retro started' and 'survey sent' pings — no summaries, Confluence or Linear
- − No public API; webhooks fire on just two events, and export is PDF, CSV, Markdown or an emailed recap
- − No SOC 2 — the ISO 27001 certificate covers the datacenter, not Echometer itself
- − Retro-side AI is one function: suggested measures. No clustering, no AI session summary
- − No scheduled retros — cadence reminders nudge the team admin, but every session is started by hand
Retro Rabbit — pros
- + Genuine Slack-first capture — notes land in the channel throughout the sprint, so the board opens full instead of starting with silent writing
- + Board covers the basics properly: drag-to-group with editable group names, dot voting with a configurable 1–50 vote budget, a shared pause/resume timer, and a per-user anonymity toggle
- + Action items carry forward — a dedicated <em>Old / Unresolved Items</em> tab plus per-room and per-person trackers, with Slack reminders to assignees
- + A GIPHY picker on notes that the marketing site never mentions — the one bit of levity on an otherwise plain board
- + Flat $30/team/month with unlimited users (3 teams of 8 = $90/mo), and CSV/XLSX/PDF export on every tier including Starter
Retro Rabbit — cons
- − Slack is the only integration — no Jira, Teams, Confluence, GitHub, Linear or Azure DevOps, and no public API, webhooks or MCP
- − No health checks, team radars or sentiment tracking; the only longitudinal view is a notes-per-day bar chart per room
- − AI is two calls — a per-retro summary and one action-item suggestion. The site's <em>intelligent note grouping</em> claim has no counterpart in the shipped web app
- − Enterprise controls are thin: SSO/SAML is Enterprise-tier only, no SCIM, no audit logs and no SOC 2 of its own. The privacy policy carries no GDPR or CCPA commitments and says retro feedback is not shared with third parties, the Slack Marketplace listing answers <em>uses large language models: no</em> and <em>has a dedicated security team: no</em>, and neither says where CarrotIQ processes notes
- − No free tier and no public changelog, from a four-person vendor whose marketing site has not changed since early 2025
