IdeaBoardz
2.9Free shared brainstorming boards
IdeaBoardz is a long-standing free brainstorming and retrospective board where anyone can spin up a shared URL, add ideas in customisable sections, vote, and export to PDF or Excel. The site is still online and the app still works, but the product appears to be in maintenance mode at best — Terms were last updated in April 2020 and there is no blog, changelog or roadmap to suggest active development.

IdeaBoardz — pros
- + Genuinely free, no paywall, no paid tier
- + No signup required to participate — just share a URL
- + 1-10 customisable sections cover most retro formats (Start/Stop/Continue, 4Ls, etc.)
- + PDF and Excel export built in
- + Voting and async input out of the box
IdeaBoardz — cons
- − UI is unchanged from the early 2010s and shows it
- − No timer, no facilitation phases, no drag-and-drop grouping
- − Zero integrations with the agile stack (Jira, Slack, Teams, Confluence, etc.)
- − Only a few starter board presets; no real template library, no health checks, no AI features
- − Boards are public-by-URL with no SSO, SOC 2, or stated privacy controls
- − Apparently in maintenance mode — Terms last updated April 2020, no changelog or blog
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
