Metro Retro
3.0Rebranded twice — Metro Retro became Ludi, now Spreo; the playful retro whiteboard lives on
Metro Retro was a fun, freeform online whiteboard built for sprint retrospectives, known for its playful templates, timer and engagement features. The product has since been renamed twice by its maker, Deqo Software Limited: to Ludi on 4 August 2025, then to Spreo on 1 July 2026 after a trademark cease-and-desist. The metroretro.io domain now 301-redirects straight to spreo.io. If you are searching for Metro Retro, the product you want is Spreo; the original Metro Retro brand and domain are no longer maintained.

Retro Rabbit
4.4Slack-first retrospectives with async note capture
Retro Rabbit is a Slack-native retrospective tool that lets teams capture notes throughout the sprint from Slack or the web app, then runs the retro on a synced board with drag-and-drop grouping, voting and assignable action items. The CarrotIQ AI layer is gated to the Pro AI plan. No public changelog and no visible feature change since April 2025 — ask for a roadmap before committing.

Metro Retro — pros
- + The product you remember still exists — it now ships as Spreo (Metro Retro → Ludi, 4 Aug 2025 → Spreo, 1 Jul 2026)
- + The vendor says accounts, boards, data and workflows carried through both renames, and old links redirect
- + Carried its playful templates, session timer 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 301-redirects straight to spreo.io
- − Two name changes in under a year (Metro Retro → Ludi → Spreo) leave stranded searchers chasing a moving target; bookmarks, runbooks and SSO configs all need updating
- − No standalone free tier under the new brand — a 30-day trial, then paid
- − The old domain isn't a clean redirect everywhere: metroretro.io/pricing returns a stale Spreo <em>Non-prod environment</em> stub instead of forwarding (checked 3 Aug 2026)
Retro Rabbit — pros
- + Genuine Slack-first workflow — notes get captured in Slack throughout the sprint, not just at retro time
- + Reduces recency bias by collecting feedback continuously instead of in a 5-minute silent write
- + Simple, opinionated UX with drag-and-drop grouping and dot voting
- + CarrotIQ covers grouping, action-item suggestions and retro summaries on the $40/team/mo Pro AI plan
- + Flat per-team pricing with unlimited users, and CSV/XLSX/PDF export on every tier including Starter
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
- − No public API, webhooks or MCP server — data leaves only as a file export
- − Enterprise controls are thin: SSO is Enterprise-tier only, no SCIM, no audit logs, and the privacy policy carries no GDPR or CCPA commitments
