Free shared brainstorming boards
Site loads and the app still functions, but the signals point to dormancy: Terms of Service last revised April 2020, no blog, changelog, news or roadmap, support address is a Gmail account, and the UI is unchanged from the early 2010s. Verify the site is still live before adopting; there are no stated persistence, security or privacy guarantees.
Best for: Throwaway retros and quick distributed brainstorms when nobody wants to sign up.
IdeaBoardz fits its pitch into a single homepage tagline:
"Brainstorm, Retrospect, Collaborate."The site invites visitors to spin up a board with one to ten customisable sections, share the URL, and let teammates add ideas asynchronously from anywhere.
It leans on usage bragging — counters on the homepage claim more than 36 million ideas across 3.3 million boards — rather than feature marketing. There is no pricing page, no enterprise pitch, no roadmap, no blog, and no comparison content. The implicit positioning is that you don't need a heavyweight retro tool: a shared URL, a few columns, voting, and an export button is enough for most distributed brainstorms and lightweight retrospectives.
IdeaBoardz is the digital equivalent of a sticky-note wall on a public wiki: cheap, frictionless, and good enough for a one-off remote retro when the team won't tolerate another login. Voting and PDF/Excel export are present, custom section counts let you DIY a Start/Stop/Continue or 4Ls board, and the no-signup link-share flow is hard to beat for ad-hoc use.
Beyond that, almost nothing the lens cares about is here: no timer, no facilitation phases, no grouping, no health checks, no Jira or Slack, no SSO, no AI, and no prebuilt templates. The Terms of Service were last updated in April 2020 and there is no public changelog, blog, or recent product news, so treat this as still online rather than actively developed. Boards are also public-by-URL with no stated security or privacy posture — fine for a classroom exercise, not for anything sensitive.
Fit: scrappy teams, workshops, and consultants running a one-off session. Not a credible choice for an ongoing agile cadence or anything an enterprise buyer would sign off on.
