Lucidspark
6.4Lucid 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, clustering, summaries) and bidirectional sync with Lucidchart for diagrams. Voting, timers and facilitator tools start at the Team tier; Breakout Boards and the Jira/Azure DevOps card sync are Enterprise-only. Strong enterprise posture inherited from Lucid: SSO/SAML, SCIM, SOC 2 Type 2, ISO 27001/27701/42001, FedRAMP, IRAP, GDPR, and US/EU/AU data residency.

RetroFlow scores 3.4 overall and is best for small or ad-hoc teams who want a genuinely free, zero-friction retro board they can share with one link — no signup, no payment and no setup, accepting that there is no timer, no integrations, no AI and no enterprise controls. It offers a free tier.

Lucidspark — pros
- + Tight integration with Lucidchart — switch between diagram and whiteboard on the same canvas
- + <em>Private mode</em> hides sticky note authors until the session ends, and a voting session can be set fully anonymous
- + Strong enterprise posture: SOC 2 Type 2, ISO 27001/27701/42001, FedRAMP, IRAP, GDPR, SSO/SAML, SCIM, US/EU/AU data residency
- + Official Lucid MCP server is GA and shipping monthly — search boards, summarise them, generate synced Jira cards from Claude or ChatGPT
- + Lucid AI is included on every tier today, free plan included
Lucidspark — cons
- − Voting, timers and facilitator tools start at the $10/user Team tier — the free plan's three boards can't run a facilitated retro
- − Breakout Boards and the Lucid Cards sync to Jira/Azure DevOps are Enterprise-only
- − 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
- − Retro template depth trails Miro and Mural, and the REST API needs a Team or Enterprise account
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 in one click and notes sync live
- + Eleven ready-made formats, up from seven — Sailboat, DAKI, Plus/Delta and Three Little Pigs are all new since the last review
- + <strong>PDF and Excel export</strong> of the finished board — new this quarter, and the only route to getting your data out
- + Light personalisation — custom column names, 2-6 columns, colour palettes and per-note emoji, with reusable saved layouts
RetroFlow — cons
- − No timer or phase controls — three separate timer requests sit unshipped on the vendor's own public roadmap, and there is no countdown anywhere in the app
- − No grouping of similar cards and no carry-over of previous action items — both still <em>Planned</em> on the roadmap
- − No integrations at all — nothing pushes to Jira, Linear, Slack or Teams, and there is no public API, webhooks or AI
- − No health checks, recurring retros, mood tracking or cross-team reporting
- − No enterprise security or compliance — no SOC 2, SSO, SCIM or audit logs, no GDPR statement in the privacy policy, and boards are private only by unguessable URL since there are no accounts
- − Built and run by a solo developer (Prashant Meena) with no support team or SLA — support routes to a personal WhatsApp number and LinkedIn DMs, and the free-tier backend still shows a ~10s cold start plus first-load errors
