RetroFlow — pros
- + Genuinely free with no paid tiers, no paywalled features and no account required to join a board
- + Anonymous feedback — participants contribute with no signup, email or PII collected
- + Three-step setup — pick a template, share the link, run the retro; participants join in one click and notes sync live
- + Eleven ready-made formats, up from seven — Sailboat, DAKI, Plus/Delta and Three Little Pigs are all new since the last review
- + <strong>PDF and Excel export</strong> of the finished board — new this quarter, and the only route to getting your data out
- + Light personalisation — custom column names, 2-6 columns, colour palettes and per-note emoji, with reusable saved layouts
RetroFlow — cons
- − No timer or phase controls — three separate timer requests sit unshipped on the vendor's own public roadmap, and there is no countdown anywhere in the app
- − No grouping of similar cards and no carry-over of previous action items — both still <em>Planned</em> on the roadmap
- − No integrations at all — nothing pushes to Jira, Linear, Slack or Teams, and there is no public API, webhooks or AI
- − No health checks, recurring retros, mood tracking or cross-team reporting
- − No enterprise security or compliance — no SOC 2, SSO, SCIM or audit logs, no GDPR statement in the privacy policy, and boards are private only by unguessable URL since there are no accounts
- − Built and run by a solo developer (Prashant Meena) with no support team or SLA — support routes to a personal WhatsApp number and LinkedIn DMs, and the free-tier backend still shows a ~10s cold start plus first-load errors
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, 15%+ off annually) with <em>unlimited members per team</em>, not per-seat
RetroTool — cons
- − <strong>Apparently dormant</strong>: blog stopped in March 2022, no changelog or release notes, legal docs unchanged since August 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
- − Most templates, image cards, named participants, private invite-only boards and zero-knowledge encryption are all behind paid tiers
- − Not SOC 2; no SSO/SCIM/audit logs for enterprise buyers
