Metro Retro
3.1Now rebranded as Ludi — the playful retro whiteboard lives on under a new name
Metro Retro was a fun, freeform online whiteboard built for sprint retrospectives, known for its playful templates, timer and engagement features. In 2024 the product was rebranded: metroretro.io now redirects to ludi.co, and the maker (Deqo Software Limited) positions Ludi as the continuation — 'Metro Retro is now Ludi.' If you are searching for Metro Retro, the product you want is Ludi; the original Metro Retro brand and domain are no longer maintained.

Metro Retro — pros
- + The product you remember still exists — it's now called Ludi
- + Carried its playful templates, timer, GIFs and icebreakers into the rebrand
- + Freeform whiteboard canvas that's friendly for engagement-first retros
Metro Retro — cons
- − The Metro Retro brand and metroretro.io domain are retired (the domain now redirects to ludi.co)
- − No standalone free tier under the new brand — Ludi is a 30-day trial then paid
- − Light on the agile stack: no Jira/Slack/Teams integrations, no SSO, no SOC 2, no AI
- − Not a dedicated retro platform — it's a general whiteboard you adapt for retros
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
