The lean-stack take

It was built for product feedback, but a lean team can use it as a digital suggestion board. People post ideas, others vote, and the roadmap shows which ideas are being worked on.

Best for

Small teams that want a free, self-hostable idea board with voting and a visible roadmap.

Watch out for

It is built for product feedback, so check that it covers your suggestion workflow, since kaizen event and PDCA tracking were not confirmed.
