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 If you are searching for Metro Retro, the product you want is Ludi; the original Metro Retro brand and domain are no longer maintained.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
RetroFlow — pros
- + Genuinely free with no paid tiers, no paywalled features and no account required to join a board
- + Anonymous feedback — participants contribute with no signup, email or PII collected
- + Three-step setup — pick a template, share the link, run the retro; participants join with one click
- + Seven ready-made retrospective formats covering the common reflection patterns
- + Real-time collaboration with live notes, dot voting and shared action items
- + Light personalisation — custom column names, 2-6 columns, 7 colour palettes and 48 emojis
RetroFlow — cons
- − No integrations at all — nothing pushes to Jira, Linear, Slack, Teams or any agile-stack tool
- − No AI features (clustering, summary, action extraction or sentiment)
- − No health checks, recurring retros, mood tracking or cross-team reporting
- − No enterprise security or compliance — no SOC 2, SSO, SCIM or audit logs; the privacy policy confirms only HTTPS and Vercel hosting with Google Analytics/PostHog analytics
- − Built and run by a solo developer (Prashant Meena) with no support team or SLA — fine for ad-hoc use, but unsuitable for enterprise procurement
- − Boards are private only by unguessable URL — there are no accounts, so no real access control, invite management or board history
