IdeaBoardz
3.1Free shared brainstorming boards
IdeaBoardz is a long-standing free brainstorming and retrospective board: pick one of five presets (Retrospective, Star Fish, Six Thinking Hats, Pros and Cons, Todos) or name your own 1-10 sections, share the URL, add ideas anonymously, upvote, and export to PDF or Excel. The app still works and is still in daily use, but development stopped years ago — the public source repository's last feature commits date to April 2020 and the Terms have not been revised since.

Reetro
6.1Fun, easy and AI-powered online retrospectives
Reetro is a lightweight retrospective tool with a genuinely free tier and a shipped app that runs well ahead of its own marketing site. Three board types — standard, phased (Reflect/Group/Vote/Discuss) and RoundUp, an async video, voice or text interview with AI-generated questions — sit alongside health checks, polls, a happiness calendar and an action tracker. AI meeting summaries, sentiment and emotion trends, auto-grouping and AI action items are quota-limited rather than paid-only, so Free gets a taste. SSO, the Scheduler and anonymous retros start on the $10/team Pro plan; data retention needs Pro Unlimited, billed at $49/month per organisation. ISO 27001 is claimed at vendor level; SOC 2 is listed as compliant, not certified.
Full review →Summary
IdeaBoardz scores 3.1 overall and is best for throwaway retros and quick distributed brainstorms when nobody wants to sign up. It offers a free tier.
Reetro scores 6.1 overall and is best for small to mid-sized agile teams who want a cheap, AI-assisted retro board — SSO, health checks, the Scheduler and anonymous retros at $10/team/mo, or $49/mo flat for the whole org — and who don't need an API or ClickUp/GitHub/Linear. It offers a free tier.
IdeaBoardz leads on open platform. Reetro leads on ease of use, retro toolkit, fun factor, AI & insights, integrations and enterprise-grade.
Across our eight scoring dimensions, Reetro edges ahead with an overall score of 6.1. That said, the right pick depends on your team — see the dimension-by-dimension breakdown below.

IdeaBoardz — pros
- + Genuinely free — no paywall, no paid tier, no trial clock
- + No signup required to participate — just share the URL
- + Five one-click presets (Retrospective, Star Fish, Six Thinking Hats, Pros and Cons, Todos), or type your own 1-10 section titles
- + Drag one sticky onto another to merge them; the votes are added together
- + PDF and Excel export on every board, plus a working phone view
IdeaBoardz — cons
- − The presets only pre-fill column titles — there is no timer, no phases and no facilitator flow behind them
- − No action-item tracking, no owners, no due dates, no carry-over between boards
- − Unlimited anonymous upvotes with no per-person vote budget
- − Zero integrations, no SSO, no SOC 2 and no published privacy policy — the URL is the only access control
- − No product work since April 2020; support is a Gmail address and a Twitter handle
Reetro — pros
- + Genuinely free tier, no credit card — 3 teams, 9 members, 6 columns and 50 guests, plus quota-limited AI (1 meeting summary, 3 auto-groupings, 3 AI action items a month)
- + <strong>SSO, the Scheduler and anonymous retros all start on the $10/team Pro plan</strong>, confirmed by the app's own upgrade copy
- + Pro Unlimited is genuinely org-wide — the app bills it at <em>$49/month per organisation</em>, not per team
- + RoundUp collects async video, voice or text feedback with AI-generated, editable interview questions — a real async mode, not just a board left open
- + AI meeting summaries carry sentiment, emotion trends (joy/trust/fear/sadness) and participation metrics, and roll up into cross-team comparison views
Reetro — cons
- − The marketing site understates the product: PDF and XLSX export, @mentions, link cards and comparative reporting are all live in the app yet tagged <em>coming soon</em> on the pricing page
- − No public API, no webhooks and no MCP server — nothing can drive Reetro programmatically
- − Slack and Teams notifications are sold, but the shipped app has no way to connect either; Confluence and Trello are export-only, a Word or CSV file plus a link to the other vendor's import instructions
- − No playable icebreakers: the in-app 'Icebreakers & Games' tiles link to four game subdomains, none of which resolves any more
- − No published Reetro-level SOC 2 Type 2 audit (the trust portal lists SOC 2 as 'compliant', ISO 27001 as 'certified'), and no SCIM
- − Anonymity is paid-only, and the Pro Unlimited plan card still reads PER TEAM while the FAQ and the app both say per organisation
