Estimioo
4.6AI-powered planning poker, retrospectives and standups for agile teams
Estimioo is a lightweight, browser-based agile-ceremony tool that bundles AI-assisted planning poker, a 42-format sprint retrospective board and async daily standups into one shared workspace. The centre of gravity is still estimation, but the retro module is a real one: one-click formats, a 2–25 minute session timer, per-card thumbs-up voting, synced icebreakers, twelve ambient and music tracks, and a Claude-powered summary that returns team mood, key themes and ranked action items. What it is not is a facilitation suite — retro cards carry their author's name and avatar with no anonymity option anywhere in the product, and there is no grouping, no dot-vote budget and no action-item owners or carry-over between sprints.

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
Estimioo scores 4.6 overall and is best for small, distributed agile teams who want fast AI-assisted planning poker and async standups at near-zero cost, plus a genuinely usable 42-format retro board — and who don't need anonymity, grouping, or action-item follow-through across sprints. 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.
Estimioo leads on value, fun factor and AI & insights. Retro Rabbit leads on retro toolkit and open platform.

Estimioo — pros
- + Genuinely cheap — flat <strong>$7/workspace/mo</strong> with unlimited participants, plus a usable free tier
- + 42 one-click retro formats, a 2–25 minute session timer and per-card upvoting — all verified in a live board
- + Unusually fun for the price: 340+ synced icebreakers, twelve ambient and music tracks, and 16 live emoji reactions
- + One-click Claude retro summary returns team mood, key themes and ranked action items with <em>Add all to board</em>
- + Full in-product UI in five languages (EN/DE/ES/FR/PT); guests join by link or QR with no signup
Estimioo — cons
- − Retro cards are <strong>attributed</strong> — author name and avatar on every note, with no anonymity option anywhere in the product
- − No grouping or clustering — dragging a card only reorders it or moves it between columns; no dot-vote budget, no action-item owners or due dates, no carry-over between retros
- − Slack and Teams are clipboard-copy buttons rather than integrations; Jira is estimation-only with write-back still on the roadmap, and there's no API, webhooks or MCP
- − No SOC 2, ISO 27001, DPA or data-residency option, and the privacy policy still dates to April 2025 — the quote-only Enterprise tier's SSO claim remains unpublished and unverified
- − Social proof is entirely unattributed — <em>450+ teams</em>, a <em>4.8</em> rating and a logo wall naming Accenture, Deloitte, Thoughtworks and Xero, with no G2, Capterra or Product Hunt listing to corroborate any of it
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
