RetroFlow
3.4Your team's favourite way to retro
RetroFlow is a free, no-signup retrospective board built by solo developer Prashant Meena, with colourful boards, real-time collaboration, 11 ready-made templates plus a custom board builder, anonymous feedback, unrestricted upvoting, drag-to-move between columns, action items and PDF/Excel export.

The board is desktop-only — any viewport under 768px is blocked outright.

Simyl Flow
5.5Measure what ships and sticks
Simyl Flow is an outcomes measurement platform for engineering teams in which the retrospective is one of five linked ceremonies (planning poker, standups, demo prep, retros, coaching). Retro boards are pre-populated with six sprint metrics pulled from Jira, Linear, GitHub and CI, AI generates candidate cards from the data, and unfinished action items carry forward — all feeding a six-dimension team health score tracked sprint over sprint.
Full review →Summary
RetroFlow scores 3.4 overall and is best for small or ad-hoc teams on laptops who want a genuinely free, zero-friction retro board they can share with one link — no signup, no payment and no setup, accepting that there is no timer, no phone support, no integrations, no AI and no enterprise controls. It offers a free tier.
Simyl Flow scores 5.5 overall and is best for engineering orgs that already run retros and want them wired into delivery data — teams asking whether last sprint's improvement actually moved cycle time, review latency or change-failure rate, rather than teams shopping for a better sticky-note board. It offers a free tier.
RetroFlow leads on ease of use, value and fun factor. Simyl Flow leads on retro toolkit, AI & insights, integrations, open platform and enterprise-grade.
Across our eight scoring dimensions, Simyl Flow edges ahead with an overall score of 5.5. That said, the right pick depends on your team — see the dimension-by-dimension breakdown below.

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 plus a Custom Board builder (2-6 columns, 7 palettes, 48 emoji) with reusable saved layouts
- + <strong>Unrestricted voting</strong> — no vote budget, no phase gate, and you can upvote your own cards; cards also drag between columns
- + PDF and Excel export of the finished board — the only route to getting your data out, and it works
RetroFlow — cons
- − No timer or phase controls — <em>still</em> nothing in the shipped app, and two timer requests raised in July 2026 sit unshipped as <em>Planned</em> on the vendor's own public roadmap
- − <strong>Desktop-only</strong> — every board route hard-blocks viewports under 768px with a 'Whoa, tiny screen detected' overlay, even though the marketing FAQ promises a fully responsive phone experience
- − No grouping of similar cards, no in-column reordering and no carry-over of previous action items; the 'Present' button is still badged SOON
- − 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
- − Solo-developer project with no support team, SLA, SOC 2, SSO or GDPR statement — support routes to a personal WhatsApp number and LinkedIn DMs, and the free-tier backend still shows a ~10s cold start plus a first-load error
Simyl Flow — pros
- + Retro boards arrive pre-populated with six sprint metrics (velocity, cycle time, PRs merged, commits, bug rate, unplanned work) pulled from the tools the team already uses, and unfinished actions carry forward with completion-rate tracking — the discussion starts from evidence, and the six-dimension health score answers whether last sprint's change actually landed
- + Unusually broad delivery-data integration set for a tool that runs retros: Jira, Linear, Shortcut, ClickUp, Notion, GitHub/GitLab Issues, plus GitHub, GitLab and Bitbucket repos and their CI pipelines for DORA metrics
- + Official remote MCP server, generally available and not tier-gated — <em>verified live</em>, with OAuth 2.1 discovery, dynamic client registration and nine read-only scopes (retros, standups, metrics, actions, poker, effectiveness, coaching), so Claude, ChatGPT, Cursor or Windsurf can query sprint data directly
- + Flat per-team pricing ($29–49/team/mo) rather than per-seat, so a 24-person org on three teams pays $87/mo regardless of headcount inside each team
- + Deliberate privacy architecture — scores are team-level not individual, coaching notes are visible only to the developer and their manager, source code is never stored, and AI runs on Amazon Bedrock with no data retention
- + Standups are the most complete module: async auto-generation, a facilitated live mode with per-person timers and presenter rotation, built-in video with smart auto-mute (1,500 min/mo on Growth), six blocker categories and AI blocker-pattern analysis
Simyl Flow — cons
- − <strong>Access is gated behind a waitlist.</strong> The header CTA across every page is now 'Join Waitlist', and the waitlist page itself redirects to sign-in — while the pricing page still sells three plans and a 30-day trial
- − Retro toolkit is thin on facilitator staples: no anonymous submission, no drag-and-drop grouping, no presentation mode, no recurring or scheduled retros, no retro-board timer, and only 5 built-in templates against 50+ at retro-native tools — and almost no engagement layer (no icebreakers, GIFs, reactions, music or kudos wall), which makes it a poor fit for teams whose retro problem is participation rather than measurement
- − The health score is computed from delivery signals, not from the team — the vendor is explicit that there are <em>"no surveys, just outcomes"</em>, so there is no survey-based health check, no sentiment analysis and no ROTI; the only mood signal is an emoji check in standups, not on the retro board
- − Enterprise claims are self-attested: 'SOC 2 aligned, not certified' and 'ISO 27001 aligned, not certified', inheriting AWS's certifications rather than holding its own; SSO/SAML sits behind a quote-only tier, there is no SCIM, and audit logs appear only as a sales-page offer rather than a plan feature
- − Export is CSV plus PDF reports, and the PDF report download is Growth-tier only; there is no public REST API and no webhooks, and the MCP server is read-only, so nothing can push data back in programmatically
- − Young vendor (Simyl AI, Inc., founded 2024, Toronto) that self-describes as 'a small team of engineers', with no named founders and still no third-party reviews, G2/Capterra listing or press coverage two years on — a real durability question for procurement
- − Free tier is genuinely small (1 team, 10 stakeholders, 2 retros/month, 1 integration, 90-day retention), and Azure DevOps is still 'coming soon' rather than shipped
