Ludi — pros
- + Genuinely delightful, illustrated UI that energises in-person and remote retros
- + Broad template library (100+) covering retros, icebreakers, planning poker, futurespectives, planning and estimation
- + Solid two-way Jira integration: backlog refinement, estimation and issue creation in-board
- + Facilitator controls, private writing mode and shareable team spaces
- + First AI feature shipped Feb 2026 — Sort into Topics auto-groups stickies into labelled topics
- + EU-hosted (Amsterdam) and GDPR-aligned (SOC 2 / ISO 27001 sit at the Digital Ocean infrastructure layer, not Ludi)
Ludi — cons
- − No async retro mode, no recurring or scheduled retros
- − No team health check or longitudinal pulse product; mood/radar work via whiteboard templates only
- − Integrations limited to Jira — no Slack, Teams, Confluence, GitHub, Linear or Azure DevOps
- − AI limited to one clustering feature — no summaries, action-item extraction, sentiment or coaching
- − No ongoing free plan; expired trials become read-only
- − SSO gated to a paid/Enterprise plan; no SCIM or audit logs advertised
Retrium — pros
- + Battle-tested five-phase guided facilitation flow
- + Anonymous brainstorming and grouping by design
- + Persistent team-room action plan that carries forward between retros
- + Team Radar covers psychological safety and custom health checks
- + Per-team-room pricing with unlimited users on every plan
Retrium — cons
- − No free tier; 30-day trial only
- − Integrations are thin beyond Jira Cloud and a <em>still-beta</em> Slack app
- − <strong>No AI features at all</strong> — no summary, clustering, action-item extraction or insights
- − No native Microsoft Teams, Azure DevOps, GitHub, Linear or Confluence integration
- − Public shipping cadence has slowed — no 2025 changelog or product blog activity visible
- − Retro-only scope; no planning poker, kudos, icebreakers or whiteboard
