Estimioo
4.1Free planning poker, retrospectives and standups for Scrum teams
Estimioo is a lightweight, browser-based agile-ceremony tool that bundles AI-assisted planning poker, a basic sprint retrospective board and async daily standups into one shared workspace. The product's centre of gravity is estimation; retrospectives are a real but thin module — a single <strong>went well / didn't go well / improve</strong> reflection board with session summaries, not a deep retro toolkit.

Retro Rabbit
4.8Slack-first retrospectives with async note capture
Retro Rabbit is a Slack-native retrospective tool that lets teams capture notes throughout the sprint with a /retro command, then runs the retro on a synced web board with voting, action items and an optional CarrotIQ AI assistant. <em>Public update cadence appears slow — verify the product is still actively maintained before committing.</em>
Full review →Summary
Estimioo scores 4.1 overall and is best for small, distributed Scrum teams who mainly want fast, AI-assisted planning poker and async standups, and are happy with a simple reflection board for retros rather than a dedicated retro suite. It offers a free tier.
Retro Rabbit scores 4.8 overall and is best for slack-centric agile teams that want to capture retro notes continuously through the sprint and run lightweight live or async retros without leaving chat. It offers paid plans from $30/mo.
Estimioo leads on value. Retro Rabbit leads on ease of use, retro toolkit, AI & insights, integrations and enterprise-grade.
Across our seven scoring dimensions, Retro Rabbit edges ahead with an overall score of 4.8. That said, the right pick depends on your team — see the dimension-by-dimension breakdown below.

Estimioo — pros
- + Genuinely cheap — flat $7/workspace/mo Team plan (not per-seat) and a usable free tier
- + Fast, no-friction planning poker with multiple scales and hidden-until-reveal voting
- + AI story-point suggestions and estimation-accuracy tracking, powered by Claude with zero data retention
- + Guests join without signup via link or QR code — low overhead for distributed teams
- + Three ceremonies (poker, retro, standup) in one shared workspace
Estimioo — cons
- − Retrospectives are a single fixed went-well/didn't/improve board — no template library, dot voting, grouping, anonymity, timer or action items with owners
- − AI is aimed at estimation, not retros — no theme clustering, sentiment or retro summaries
- − No Slack/Teams, Confluence, GitHub, Linear or Azure DevOps integrations; Jira is a paste-URL preview for poker only
- − No SSO, SOC 2, audit logs or published data-residency — not built for enterprise procurement
- − Free sessions expire after 1 hour and cap at 5/month; no recurring retros or persistent retro history
Retro Rabbit — pros
- + Genuine Slack-first workflow — capture notes via /retro during the sprint, not just at retro time
- + Reduces recency bias by collecting feedback continuously, not in a 5-minute silent write
- + Simple, opinionated UX with drag/drop grouping and dot voting
- + CarrotIQ AI handles grouping, action items and summaries on the Pro AI plan
- + Per-team flat pricing scales cleanly for small squads
Retro Rabbit — cons
- − Slack is the only chat/issue-tracker integration — no Jira, Teams, Confluence, GitHub, Linear or Azure DevOps
- − No health checks, team radars or longitudinal trend reporting
- − No org-level dashboards, cross-team rollups or action kanban
- − Enterprise controls are thin: SSO is Enterprise-tier only, no SCIM, no audit logs, no documented GDPR posture
- − Per-team flat pricing — 3 teams of 8 lands at $90/mo on the Starter tier
