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.

Trune.io
4.1Structured online retrospectives with team radar
Trune (formerly Fraankly) is an EU-built retrospective and team-feedback tool that runs a fixed four-phase session — silent writing, presenting, voting, actions — with 14 pre-built templates plus custom ones, anonymous cards, drag-to-group clustering, dot voting, action items with reminder emails, and team radars including the Spotify Squad Health Check. Hosted in Frankfurt with EU-only application data, available in five UI languages, and exports results to Excel, CSV or an emailed PDF.
Full review →Summary
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.
Trune.io scores 4.1 overall and is best for small EU-based agile teams that want a simple, <strong>GDPR-aligned</strong> retro tool with templates, grouping, voting, and team radars — and can live with a vendor whose app has not shipped an update since September 2025. It offers a free tier.
Retro Rabbit leads on ease of use, fun factor and AI & insights. Trune.io leads on retro toolkit, integrations and open platform.
Across our eight scoring dimensions, Retro Rabbit edges ahead with an overall score of 4.4. That said, the right pick depends on your team — see the dimension-by-dimension breakdown below.

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
Trune.io — pros
- + EU/Frankfurt data residency and a GDPR-first posture — the FAQ states no application data is stored outside Europe
- + Per-team (not per-seat) pricing: $19/mo covers unlimited members, and the free tier gives 5 sessions
- + Native two-way Azure DevOps sync on the Enterprise plan — action items out as work items, Done status back in
- + Team radars include the Spotify Squad Health Check plus fully custom radars
- + Ships in five UI languages (English, German, Dutch, French, Italian) and exports to Excel, CSV or an emailed PDF
Trune.io — cons
- − <strong>The product has stood still</strong>: the web app was last deployed in September 2025, the blog stopped in July 2024, there is no changelog, and the Android app is gone from Google Play
- − No SCIM, SOC 2 or audit logs, and SSO only as a bespoke per-customer SAML setup — not enterprise-ready
- − No AI: the code carries a truneGPT chat window, but nothing in the interface opens it
- − Azure DevOps is the only native connector and is Enterprise-only (quote-based); everything else is a single one-way Zapier trigger
