NimbleRetro
3.6Time-boxed retros with 5-Why root cause analysis
NimbleRetro is the retrospective module inside NimbleWork's broader Nimble agile platform. It runs structured, time-bound retros through Icebreaker, Ideation, Grouping, Voting, and Root Cause Analysis stages, with anonymous input, action item tracking, and a 5-Why root cause workflow. Native iOS and Android apps complement the web product, and action items convert directly into Nimble workitems (user stories and cards).

Reetro
6.0Fun, easy and AI-powered online retrospectives
Reetro is a lightweight retrospective tool with a genuinely free tier, a scheduler that auto-creates recurring boards, and AI-powered paid tiers covering meeting summaries, sentiment analysis, AI card grouping, customizable health checks and an action tracker. SSO, 2FA and audit logs start on the $10/team Pro plan rather than an enterprise tier. ISO 27001 is claimed at the vendor level; SOC 2 is described as compliance on SOC 2-certified infrastructure rather than a published Reetro-level Type 2 audit.
Full review →Summary
NimbleRetro scores 3.6 overall and is best for small agile teams that want a no-frills retro with built-in root cause analysis and a mobile companion app, especially teams already using the wider NimbleWork (SwiftKanban / Nimble) suite. It offers paid plans from $10/user/mo (Nimble Team tier, USD; standalone NimbleRetro is quote-only).
Reetro scores 6.0 overall and is best for small to mid-sized agile teams who want a low-cost, easy retro board with AI summaries, customizable health checks, SSO from the $10/team tier and Jira/Azure DevOps export — with a flat-rate org-wide tier if you outgrow per-team pricing. It offers a free tier.
NimbleRetro leads on open platform. Reetro leads on ease of use, retro toolkit, value, fun factor, AI & insights, integrations and enterprise-grade.
Across our eight scoring dimensions, Reetro edges ahead with an overall score of 6.0. That said, the right pick depends on your team — see the dimension-by-dimension breakdown below.

NimbleRetro — pros
- + Structured 5-Why root cause workflow built into the retro flow
- + Anonymous input and time-bound stages keep retros focused
- + Native iOS and Android apps for mobile participation
- + NimbleWork runs an annual SOC 2 Type II audit and an ISO/IEC 27001:2022 audit, with SAMLv2/ADFSv3 SSO at the platform level
- + Action items convert directly into Nimble work items, so follow-up lands in the same backlog the team already works from
NimbleRetro — cons
- − Only four templates, and custom templates cap out at four columns
- − No SCIM provisioning or audit logs documented; SSO and the SOC 2 / ISO 27001 attestations sit at the NimbleWork platform level, not the retro module
- − Comparison pages tick 'Generative AI' for NimbleRetro, but no retro AI (clustering, summaries, sentiment) is documented — NimbleWork's AI Agents are a separately licensed add-on aimed at Nimble cards and analytics
- − No documented export of a retro board in any format
- − Thin direct-integration story for the agile stack — no documented Jira, GitHub, Linear, or Azure DevOps hooks for the retro module
- − Participants are limited to members of the Nimble project the retro is created from
- − NimbleRetro's own pricing page is demo-gated; the only published rate card is the Nimble suite's ($10/user/mo Team, $26/user/mo Business)
Reetro — pros
- + Genuinely free tier, no credit card — 3 teams, 9 members and 50 guests covers a 24-person org
- + <strong>SSO (Google, OneLogin, Azure AD, Okta), 2FA and audit logs start on the $10/team Pro plan</strong>, not an enterprise tier
- + Scheduler auto-creates the next retro board weekly or every 2–4 weeks with layout and settings pre-applied
- + AI meeting summaries, sentiment analysis and automatic card grouping on paid, alongside customizable health checks, polls and a happiness index
- + Trust center is actively maintained — policy pack, sub-processor list and an AI governance portal all published or refreshed in 2026
Reetro — cons
- − Free plan capped at 3 teams, 9 members, 10 active boards and 4 columns, with both anonymity and multi-voting paid-only
- − Pro Unlimited's own marketing is self-contradictory — the FAQ and plan table call it flat org-wide $49/mo while the plan card badge says PER TEAM with a 180-member cap
- − Team, comparative and monthly reporting are ticked on the paid columns yet tagged <em>coming soon</em> in the same table — verify the reporting story before you buy
- − On-premises is sold as a Pro Unlimited feature but the tooltip on that plan card says 'coming soon'
- − No published Reetro-level SOC 2 Type 2 audit (their trust center lists SOC 2 as 'compliant', not certified) and no SCIM
- − No public API, webhooks or MCP server; no GitHub/Linear; help-doc footers still read 2020–2021 and there's no public changelog
