IdeaBoardz
2.6Free 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.

Miro

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
Miro — pros
- + Enormous template library (5,000+) and Miroverse community for retro formats
- + AI clustering groups sticky notes by sentiment, tag, author and keyword; Sidekicks and Flows extend AI deeper into the canvas
- + Best-in-class integration catalog (Jira, Azure DevOps, Asana, Linear, ClickUp, Confluence, Slack, Teams) with two-way card sync
- + Enterprise-grade SSO, SCIM, audit logs, ISO 27001, ISO 42001 (AI governance) and EU/US/AU data residency
- + Same canvas works for discovery, planning and retros — no context switching
Miro — cons
- − Per-seat pricing: a 24-person org pays ~$192/mo on the Starter tier (annual), well above retro-native tools at that headcount
- − No native health checks, mood tracking or longitudinal team-pulse
- − No recurring retros, scheduling, action carryover or cross-team rollup — facilitators rebuild structure each sprint
- − Full two-way card sync (Linear, ClickUp, Azure DevOps) and SSO sit behind the $20/user/mo Business tier; SCIM and audit logs only on Enterprise (30-seat min)
- − No built-in retro report or action-tracker dashboard
