IdeaBoardz
2.9Free 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.

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
LetRetro — pros
- + Flat per-team pricing ($11.99/team/mo) with unlimited members — cost scales with the number of teams, not headcount, so growing teams aren't penalised per seat
- + AI is a genuine strength rather than a single bolt-on: sentiment analysis, key takeaways, improvement suggestions and automated retro documentation
- + Built-in team-health and happiness tracking with sprint-over-sprint trend dashboards
- + Real-time collaborative rooms (live cursors, drag-and-drop cards, anonymous voting, live polls) that spin up in seconds with no setup
- + Confluence and Notion sync plus action-item push to Jira, Slack notifications and webhooks for custom workflows
LetRetro — cons
- − Thin enterprise story: SSO arrives only on the Business tier, with no published SCIM, audit logs, or LetRetro-held SOC 2 / ISO 27001 — it relies on SOC 2-compliant hosting infrastructure rather than its own certification
- − Founder-led Bengaluru startup with a very thin public track record — a single third-party review (one 5-star SaaSHub rating, from a customer LetRetro also features on its homepage) and no presence in the major 2026 'best retro tools' roundups — a durability risk for enterprise procurement
- − Retro toolkit lacks some facilitator staples: no confirmed recurring/scheduled retros, parking lot, team agreements, or async-first mode — the product is built around live, real-time sessions
- − Integration set is modest — no Microsoft Teams, GitHub, Linear or Azure DevOps — and the Notion/Confluence connectors are documentation sync rather than deep two-way workflow
- − Free tier caps rooms at 3 and AI at 10 chats per day, so regular AI use pushes teams onto the paid plan quickly
