IdeaBoardz
3.6Free 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.)
- − No prebuilt templates, 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
Reetro — Pros
- + Generous free tier with no credit card required
- + Per-team Pro pricing ($29/team/mo) keeps costs predictable for small squads
- + AI summaries, sentiment analysis and monthly reports included on paid
- + Customizable team health checks, polls and a happiness index
- + ISO 27001 certified with SOC 2 alignment and audit logs
Reetro — Cons
- − Free plan capped at 3 teams, 9 members, 10 boards/month and 4 columns, with anonymity now paid-only
- − Voting is essentially upvote/downvote — no vote-on-ideas-in-groups
- − Reporting & analytics screens (team reporting, comparative reporting, monthly reporting, PDF export) still listed as <em>coming soon</em>
- − Several quality-of-life features flagged 'coming soon' — link cards, @mentions, scheduler, icebreakers, on-premises, in-app notifications
- − No public changelog or release notes — hard to verify what's shipped recently from the outside
- − No planning poker, whiteboard, presentation mode, mobile app, or GitHub/Linear integrations
