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.
