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 If you are searching for Metro Retro, the product you want is Ludi; the original Metro Retro brand and domain are no longer maintained.

Echometer — pros
- + Health-check question library grounded in University of Münster psychology research
- + Strong longitudinal pulse and team-radar reporting tied to retros
- + EU-only data residency (Open Telekom Cloud, Germany) with GDPR DPA
- + AI Co-Pilot clusters ideas and proposes SMART action items
Echometer — cons
- − Thin chatops integrations — no native Slack, Teams or Confluence
- − No SOC 2; relies on ISO 27001 datacenters and EU residency
- − 1:1 meetings and the deepest AI live in a separate paid product
- − No native scheduling or recurring retros — sessions start manually
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
