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.

4.3Structured 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 4.3 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 public site is currently offline and whose app has not shipped a release in a year. 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, no SOC 2 of its own, the privacy policy carries no GDPR or CCPA commitments, and the Slack Marketplace listing records <em>has a dedicated security team: no</em>
- − 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 GDPR-first posture — even the truneGPT 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
- + Ships in five UI languages (English, German, Dutch, French, Italian) and exports to Excel, CSV or an emailed PDF
Trune.io — cons
- − <strong>trune.io has been returning a WordPress fatal error on every page since late July 2026</strong> — pricing, sign-up and support included. Only the app at app.trune.io still loads
- − No SSO, SCIM, SOC 2, or audit logs — not enterprise-ready
- − Both native mobile apps are 404 on the App Store and Google Play, and the web app has not been redeployed since September 2025
- − AI stops at truneGPT, a ChatGPT-4 chat assistant — no clustering, summaries or action extraction
- − Azure DevOps is the only native connector and needs the pricier Professional tier; everything else is a single one-way Zapier trigger
