Lucidspark
6.6Lucid Software's whiteboard with the Lucid AI assistant, breakout boards and tight Lucidchart integration
Lucidspark is the whiteboard product from Lucid Software (makers of Lucidchart) — an infinite canvas with sticky notes, voting, timer, breakout boards, the Lucid AI conversational assistant (prompt-to-board, clustering, summaries), and bidirectional sync with Lucidchart for diagrams. Strong enterprise posture inherited from Lucid: SSO/SAML, SCIM, SOC 2 Type 2, ISO 27001/27701, FedRAMP, 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 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If you are searching for Metro Retro, the product you want is Ludi/Spreo; the original Metro Retro brand and domain are no longer maintained.

Lucidspark — pros
- + Tight integration with Lucidchart — switch between diagram and whiteboard on the same canvas
- + Breakout Boards let you split a workshop or retro into parallel rooms
- + Strong enterprise posture: SOC 2 Type 2, ISO 27001/27701, FedRAMP, GDPR, SSO/SAML, SCIM, US/EU/AU data residency
- + Generous integration set: Jira, Slack, Teams, Confluence, Azure DevOps, Asana
- + Free tier exists and is enough to evaluate the tool
Lucidspark — cons
- − No native anonymous voting — names always visible on stickies
- − No health checks, recurring retros, action carryover or cross-team rollup
- − AI is general brainstorming/clustering, not retro-aware — no sentiment, action-item extraction or trend insight across retros
- − Free tier is capped at 3 editable boards — enough to evaluate, not to run recurring retros
- − Brand is best known for diagramming; retro template depth trails Miro and Mural
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
