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.

RetroTool
3.2Anonymous online retrospectives, no login required
RetroTool is a low-friction online retrospective board built by u2i, a ~60-person NY/Kraków software agency, as an internal tool it later opened up. Free anonymous retros run from a unique URL with no signup; paid tiers add private boards, team management, configurable retention and zero-knowledge encryption. The product works and is still used daily, but nothing has shipped visibly since 2024.
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.
RetroTool scores 3.2 overall and is best for small or ad-hoc teams who want a free, no-signup retro board with private drafting, secret voting and a dozen standard templates — provided you're comfortable running on a tool whose last visible build is dated May 2024. It offers a free tier.
Retro Rabbit leads on retro toolkit, fun factor, AI & insights, integrations, open platform and enterprise-grade. RetroTool leads on value.
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
RetroTool — pros
- + Genuinely free anonymous retros with no account required
- + Three-click setup — unique URL, share, run
- + Per-column Private Sections keep drafting unbiased until people publish
- + Zero-knowledge encryption with custom passwords on the Company plan
- + Per-team flat pricing ($10 or $20/team/mo, 15%+ off annually) with <em>unlimited members per team</em>, not per-seat
RetroTool — cons
- − <strong>Dormant</strong>: the marketing build is dated 28 May 2024, the app still runs Meteor 2.9, the blog stopped in March 2022 and the legal pages are unchanged since August 2020
- − No native integrations with Jira, Slack, Teams or any agile-stack tool
- − No AI features (clustering, summary, action extraction, sentiment)
- − No health checks, recurring retros, async mode, or cross-team reporting
- − Export is Markdown only (plain or Confluence-flavoured), copied to the clipboard
- − Most templates, image cards, named participants, private invite-only boards and zero-knowledge encryption sit behind paid tiers
- − Not SOC 2; Google sign-in only, with no SAML SSO, SCIM or audit logs
