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, 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 Breakout Boards plus 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.

RetroFlow
3.4Your team's favourite way to retro
RetroFlow is a free, no-signup retrospective board built by solo developer Prashant Meena, with colourful boards, real-time collaboration, 11 ready-made templates plus a custom board builder, anonymous feedback, unrestricted upvoting, drag-to-move between columns, action items and PDF/Excel export. Participants join a shared link in one click with no account; the whole product is free with no paid tiers or locked features. The board is desktop-only — any viewport under 768px is blocked outright.
Full review →Summary
Lucidspark scores 6.4 overall and is best for engineering and PM teams already on Lucidchart who want sticky-note retros and brainstorming on the same platform — and whose security review favours a SOC 2 / ISO 27001 vendor. It offers a free tier.
RetroFlow scores 3.4 overall and is best for small or ad-hoc teams on laptops 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 phone support, no integrations, no AI and no enterprise controls. It offers a free tier.
Lucidspark leads on retro toolkit, fun factor, AI & insights, integrations, open platform and enterprise-grade. RetroFlow leads on ease of use and value.
Across our eight scoring dimensions, Lucidspark edges ahead with an overall score of 6.4. That said, the right pick depends on your team — see the dimension-by-dimension breakdown below.

Lucidspark — pros
- + Tight integration with Lucidchart — switch between diagram and whiteboard on the same canvas
- + <em>Private mode</em> works on every plan, free included: it hides sticky note contents and authors, and the facilitator can keep authors hidden permanently
- + 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 is included 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
- − 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 of Enterprise
- − 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
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 plus a Custom Board builder (2-6 columns, 7 palettes, 48 emoji) with reusable saved layouts
- + <strong>Unrestricted voting</strong> — no vote budget, no phase gate, and you can upvote your own cards; cards also drag between columns
- + PDF and Excel export of the finished board — the only route to getting your data out, and it works
RetroFlow — cons
- − No timer or phase controls — <em>still</em> nothing in the shipped app, and two timer requests raised in July 2026 sit unshipped as <em>Planned</em> on the vendor's own public roadmap
- − <strong>Desktop-only</strong> — every board route hard-blocks viewports under 768px with a 'Whoa, tiny screen detected' overlay, even though the marketing FAQ promises a fully responsive phone experience
- − No grouping of similar cards, no in-column reordering and no carry-over of previous action items; the 'Present' button is still badged SOON
- − 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
- − Solo-developer project with no support team, SLA, SOC 2, SSO or GDPR statement — support routes to a personal WhatsApp number and LinkedIn DMs, and the free-tier backend still shows a ~10s cold start plus a first-load error
