Quick Verdict
Both of these are web-based retro tools with AI summaries and a free tier. That's where the overlap stops.
Kollabe is an all-in-one agile platform. It runs retrospectives, planning poker, and async daily standups, with 600+ icebreaker questions and over 1,000 templates. Reetro is a focused retrospective board. It does retros well, adds AI summaries and grouping, and posts results to Slack and Microsoft Teams. No planning poker, no standups.
That Slack and Teams integration is a real edge, and it's one Kollabe can't match. Kollabe has no chat-tool integration whatsoever. If your team runs retros from inside Slack and wants action items dropped into a channel, Reetro does that and Kollabe doesn't.
For everyone else, Kollabe wins. You get more ceremonies, deeper AI, more export options, and a higher overall rating (4.5 vs 3.6) for $29/month flat.
Feature Comparison
Strip both down to a single retro board and they look similar. Anonymous mode, voting, a timer, action items, AI summaries, AI grouping, sentiment analysis. Reetro covers the fundamentals and adds nice facilitator touches like card masking, a "Swiss Timer," background music, and a confetti button.
The gap shows up the moment you ask what else the tool does.
Kollabe is built for the whole sprint. Planning poker comes with Jira, GitHub, Azure DevOps, and Linear ticket import, plus auto-sync of winning estimates back to your tracker. Async standups run in a persistent daily room with AI summaries you can scope to a group. Reetro has neither. It's retro-only, with team health checks as the one extra format.
Templates are not close. Kollabe ships over 1,000 templates and an AI template generator that builds a custom board from a theme or goal. Reetro offers around 18 to 20. For a team that wants the same Mad/Sad/Glad every sprint, that doesn't matter. For a facilitator who likes to vary the format, it does.
Reetro is a retro board. Kollabe is a retro board plus a poker tool plus a standup tool. If you only run retros, that breadth is wasted on you. If you run the full set of agile ceremonies, it replaces two or three separate subscriptions.
Kollabe also has the extras that make sessions feel less flat: inline polls any member can spin up, a built-in drawing canvas, themed retros with 30+ backgrounds, kudos, GIFs, and threaded comments. Reetro keeps it leaner. That's a fair design choice, not a flaw, but it's a difference worth knowing before you buy.
Pricing Comparison
Both bill per team, not per user, so the math depends on how many squads you have.
Kollabe
Flat per team — retros, poker, and standups included
- Unlimited participants and history
- All AI features included
- All integrations included
- Free tier capped at 10 participants
Reetro
Pro plan, billed annually ($39 monthly)
- 60 members and 60 boards per team
- Slack and Microsoft Teams integration
- Anonymous mode (Pro and up only)
- Free tier with 3 teams, 9 members each
On price alone, Kollabe's $29 undercuts Reetro's $32 annual (or $39 monthly) Pro plan, and you get more in the box. Reetro's free tier is more generous on team count (3 teams vs Kollabe's single free workspace), but it's tightly capped: 9 members, 6 columns, 10 boards, and no anonymous mode. Anonymous feedback is a paid feature on Reetro, which surprises a lot of teams.
The bigger value gap is what each $30-ish unlocks. Reetro buys you a better retro board with chat notifications. Kollabe buys you retros, poker, and standups together. If you'd otherwise pay separately for an estimation tool and a standup tool, Kollabe is the cheaper total by a wide margin.
Reetro's Business tier ($55 annual) adds an on-premises option and advanced reporting, which Kollabe doesn't offer at any price. For a team that needs self-hosting, that's a genuine reason to look at Reetro.
Ease of Use
Both are quick to start. No installs, share a link, and people are in. Reetro's board is clean and the phased board type walks a group through brainstorm, group, vote, and discuss in order. Card masking hides responses until the discussion phase, which keeps people from anchoring on the first idea posted. It's a well-mannered little tool.
Kollabe's facilitation is more flexible. You get guided phases, but the facilitator can move between them freely, and AI grouping removes the manual clustering step. For an experienced scrum master that flexibility is welcome. For someone running their first few retros, Reetro's tighter, more linear flow has fewer ways to lose the room.
Neither has a native mobile or desktop app. Both are browser-based, and both are responsive enough to limp through on a phone in a pinch.
Integrations
This is Reetro's standout category and the one place it clearly beats Kollabe.
Reetro connects to Slack and Microsoft Teams. You can run a retro, collect feedback, and push action items without leaving the chat tool your team already lives in. It also exports action items to Jira, Azure DevOps, Confluence, and Trello, and can send summaries by Gmail or email. Imports are limited to chat tools, but for a lot of teams that's exactly the workflow they want.
Kollabe goes deeper but narrower. It does two-way sync with Jira, GitHub, Azure DevOps, and Linear: import tickets into a poker session, then write winning estimates back as story points. Action items export to Jira, GitHub Projects, and Linear. Confluence export is there too. But there is no Slack and no Microsoft Teams, full stop.
If your retros and action items need to land in Slack or Microsoft Teams, Reetro is the only one of these two that can do it. Kollabe has no chat integration at all, and that won't change by your next sprint.
So the integration story splits cleanly. Reetro wins if your hub is a chat tool. Kollabe wins if your hub is your issue tracker and you want live two-way estimate sync during planning.
AI and Automation
Both lean on AI for the same two jobs: summarizing a session and grouping similar cards. Reetro's AI meeting summary also reads sentiment and emotional dynamics across the board, and its scheduler can auto-create boards and fire reminders. For a retro-only tool, the AI is solid.
Kollabe's AI reaches further because it has more surfaces to work on. Retro summaries are customizable with your own AI instructions, so you can tell it to focus on deployment pain or team morale. Standup summaries run daily, weekly, or fortnightly. The AI template generator builds a board from a prompt. Sentiment tracking spans sessions over time.
Neither is doing anything radical with AI here, and I'd be skeptical of any retro tool that claims it is. The honest read: Reetro's AI is good for a single board, and Kollabe's does the same things plus extends across standups and template creation. The custom-instruction control on summaries is the feature I'd actually miss.
Who Should Choose Which?
Choose Kollabe if…
- You run retros, planning poker, and standups and want one tool, not three
- You need ticket import and auto estimate sync from Jira, GitHub, Linear, or Azure DevOps
- You want 1,000+ templates and an AI generator instead of ~20 fixed formats
- You like inline polls, a drawing canvas, themed boards, and kudos in your retros
- A flat $29/month with unlimited participants fits how your team is sized
Choose Reetro if…
- Your team runs retros from inside Slack or Microsoft Teams
- You only need retros and health checks, not poker or standups
- You want a clean, linear board that's easy for new facilitators
- You need an on-premises install option (Business plan)
- You're fine paying for anonymous mode and want a lean, focused tool
Final Recommendation
For most teams, Kollabe is the better buy. One $29/month subscription covers retros, planning poker, and async standups, with deeper AI, far more templates, and more export formats. Reetro does one of those three things and charges about the same for it.
But be honest about the Slack and Microsoft Teams gap, because it's a real one. If your team's whole rhythm runs through a chat tool and you want retros and action items posted there, Reetro can do that today and Kollabe can't. That, plus an on-premises option, are the two reasons I'd point someone toward Reetro over Kollabe.
Pick Kollabe if you want a single platform for the whole sprint. Pick Reetro if you want a focused retro board that lives in Slack or Teams. If you're still mapping out which formats your team should even run, our retrospective formats guide is a good next stop.
