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.

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.

RetroFlow — pros
- + Genuinely free with no paid tiers, no paywalled features and no account required to join a board
- + Anonymous feedback — participants contribute with no signup, email or PII collected
- + Three-step setup — pick a template, share the link, run the retro; participants join in one click and notes sync live
- + Eleven ready-made formats plus a Custom Board builder (2-6 columns, 7 palettes, 48 emoji) with reusable saved layouts
- + <strong>Unrestricted voting</strong> — no vote budget, no phase gate, and you can upvote your own cards; cards also drag between columns
- + PDF and Excel export of the finished board — the only route to getting your data out, and it works
RetroFlow — cons
- − No timer or phase controls — <em>still</em> nothing in the shipped app, and two timer requests raised in July 2026 sit unshipped as <em>Planned</em> on the vendor's own public roadmap
- − <strong>Desktop-only</strong> — every board route hard-blocks viewports under 768px with a 'Whoa, tiny screen detected' overlay, even though the marketing FAQ promises a fully responsive phone experience
- − No grouping of similar cards, no in-column reordering and no carry-over of previous action items; the 'Present' button is still badged SOON
- − No integrations at all — nothing pushes to Jira, Linear, Slack or Teams, and there is no public API, webhooks or AI
- − No health checks, recurring retros, mood tracking or cross-team reporting
- − Solo-developer project with no support team, SLA, SOC 2, SSO or GDPR statement — support routes to a personal WhatsApp number and LinkedIn DMs, and the free-tier backend still shows a ~10s cold start plus a first-load error
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
