RetroTool
4.4Anonymous online retrospectives, no login required
RetroTool is a low-friction online retrospective board built by NY/Poland software agency u2i as a side project.

Sprintlio
4.1Retrospectives with accountability via Slack and Jira
Sprintlio is a retrospective tool built around <strong>action follow-through</strong>, with Slack and Jira flows so action items don't die in a board after the meeting ends. Development appears to have largely stalled — the homepage still carries a 2023 copyright, there is no public changelog, and the last Product Hunt launch was February 2019.
Full review →Summary
RetroTool scores 4.4 overall and is best for small or ad-hoc teams who want a free, no-signup retro board with secret voting and a few standard templates — provided you're comfortable using a tool that hasn't shipped visible updates in years. It offers a free tier.
Sprintlio scores 4.1 overall and is best for small agile teams that already live in Slack and Jira and want lightweight retros where action items get pushed back into the daily workflow. It offers paid plans from $50/user/mo.
RetroTool leads on ease of use, value and fun factor. Sprintlio leads on integrations and enterprise-grade.
Across our seven scoring dimensions, RetroTool edges ahead with an overall score of 4.4. That said, the right pick depends on your team — see the dimension-by-dimension breakdown below.

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
Sprintlio — Pros
- + Action items sync to Jira and Slack — follow-through is the product's actual reason for being
- + Slack-native flows: run recaps, reminders and notifications from the channel
- + Simple, focused retro workflow without the all-in-one bloat
Sprintlio — Cons
- − Vendor site shows few signs of recent development — copyright still reads 2023 and the last public launch was 2019
- − Almost no AI, no health checks, no cross-team reporting — feature surface is thin by 2026 standards
- − No published pricing page, no documented SSO/SCIM/SOC 2 — enterprise readiness is unclear at best
- − Integration surface is narrow: Jira and Slack only, no Teams, Azure DevOps, GitHub, Linear or Confluence
