RetroTool — Pros
- + Genuinely free anonymous retros with no account required
- + Three-click setup — unique URL, share, run
- + Zero-knowledge encryption with custom passwords on Company plan
- + Per-team flat pricing ($10 or $20/team/mo) rather than per-seat
RetroTool — Cons
- − <strong>Apparently dormant</strong>: no blog, changelog or release notes; legal docs last updated 2020
- − No native integrations with Jira, Slack, Teams or any agile-stack tool
- − No AI features (clustering, summary, action extraction, sentiment)
- − No health checks, recurring retros, or cross-team reporting
- − Secret voting and private boards locked behind paid tiers
- − Not SOC 2; no SSO/SCIM/audit logs for enterprise buyers
Trune.io — Pros

- + Free tier covers 5 full-featured sessions, no card required

- − Light on facilitation extras: no parking lot, agenda planner, async mode, or drag-and-drop grouping
- − Reporting is limited to per-team stats; no cross-team or org rollups
