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 rebranded twice by its maker, Deqo Software Limited: to Ludi in August 2025, then to Spreo. The metroretro.io domain now 301-redirects all the way through to spreo.io. If you are searching for Metro Retro, the product you want is Ludi/Spreo; the original Metro Retro brand and domain are no longer maintained.

Metro Retro — pros
- + The product you remember still exists — it's now called Spreo (renamed from Ludi on 1 July 2026)
- + 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 through to spreo.io)
- − Two brand changes in under a year (Metro Retro → Ludi → Spreo) can leave stranded searchers chasing a moving target
- − No standalone free tier under the new brand — it's a 30-day trial then paid
- − Not a dedicated retro platform — it's a general whiteboard you adapt for retros
RetroTool — pros
- + Genuinely free anonymous retros with no account required
- + Three-click setup — unique URL, share, run
- + Zero-knowledge encryption with custom passwords on Company plan
- + Per-team flat pricing ($10 or $20/team/mo) rather than per-seat
RetroTool — cons
- − <strong>Apparently dormant</strong>: no blog, changelog or release notes; legal docs last updated 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, or cross-team reporting
- − Private invite-only boards and zero-knowledge encryption locked behind paid tiers
- − Not SOC 2; no SSO/SCIM/audit logs for enterprise buyers
