Lucidspark
6.5Lucid Software's whiteboard with the Lucid AI assistant and tight Lucidchart integration — voting, timers and facilitator tools start at the Team tier
Lucidspark is the whiteboard product from Lucid Software (makers of Lucidchart) — an infinite canvas with sticky notes, private-mode brainstorming, anonymous voting sessions, timers, the Lucid AI assistant (prompt-to-board, magic sort, board summaries) and bidirectional sync with Lucidchart for diagrams. Free and Individual get static dot voting only; the timer, private voting and facilitator tools start at the Team tier, and starting a private-mode session, Breakout Boards and the Lucid Cards sync to Jira/Azure DevOps/monday.com are Enterprise-only. Strong enterprise posture inherited from Lucid: SSO/SAML, SCIM, SOC 2 Type II, ISO 27001/27701/42001, FedRAMP Moderate, IRAP PROTECTED, GDPR, and US/EU/AU data residency.

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 If you are searching for Metro Retro, the product you want is Spreo; the original Metro Retro brand and domain are no longer maintained.

Lucidspark — pros
- + Tight integration with Lucidchart — switch between diagram and whiteboard on the same canvas
- + Engagement basics on every plan, free included — emoji reactions on notes, Giphy search and a free icebreaker template library; from Team the timer can play music for the whole board
- + Strong enterprise posture: SOC 2 Type II, ISO 27001/27701/42001, FedRAMP Moderate, IRAP PROTECTED, PCI DSS, GDPR, SSO/SAML, SCIM, US/EU/AU data residency
- + Official Lucid MCP server is GA on every plan and shipping monthly — search boards, summarise them, generate synced Jira cards from Claude or ChatGPT
- + Lucid AI (AI sort, summaries, prompt-to-board and a chat assistant) is unmetered on every tier today, free plan included
Lucidspark — cons
- − Timer, private voting and facilitator tools start at the $10/user Team tier — Free and Individual get static dot voting and nothing else facilitator-shaped
- − Starting a private-mode (blind brainstorm) session, Breakout Boards and the Lucid Cards sync to Jira, Azure DevOps and monday.com are Enterprise-only; audit logs need the paid Enterprise Shield add-on on top
- − No health checks, recurring retros, action carryover or cross-team rollup
- − AI is general brainstorming/summarising, not retro-aware — no sentiment, action-item extraction or trend insight across retros
- − Retro template depth trails Miro and Mural; the REST API needs a Team or Enterprise account and there are no outbound webhooks
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
