01
No account, no friction
No email, no password. Pick an emoji avatar and a nickname, you’re in. A room spins up in under five seconds.
Planning poker, next generation
Estimate your stories, reveal in one beat, repeat.
Scrumbler is an anonymous-by-default, no-account, real-time planning poker. It makes sprint planning come alive: everyone speaks up, hidden assumptions surface, and estimating becomes a moment that brings the team together.
No account. Share a room code, that’s it.
Why Scrumbler
Agile estimates shouldn’t require an account, an onboarding, or a spreadsheet.
02
Anonymous by default
Votes stay hidden until reveal. Nobody anchors on the first card down: everyone plays their real number, and the gaps become the starting point for a real conversation.
03
Real-time, truly
Real-time sync, sub-second latency. When a teammate votes, you see it in the same heartbeat. The tech stays invisible, in service of the ritual.
What you’ll love
Everything you need to estimate fast, and nothing more.
Dedicated roles
Scrum Master or Developer, each sees the screen built for the job: one runs the session, the other focuses on the vote.
Fibonacci cards
The agile classic: 1, 2, 3, 5, 8, 13, 21, ?, ☕. A ☕ card to call a break, a ? to call out missing info.
Theatrical reveal
Revealing the votes turns into a little show: confetti, an animated scoreboard, and that rush right before the cards flip.
Targeted discussion
When a vote stands out, Scrumbler opens the floor with kindness: every point of view is valuable info for a better estimate.
One-click re-vote
Mind changed? Click your card again, the vote turns private. No need to restart the round.
Session recap
Timeline of stories, markdown export, shareable summary. Next refinement starts with full context.
How it works
Three steps, not one more.
- 01
Create the room
Pick a nickname, an emoji avatar, a role. You get a code to share, no email invites.
- 02
Share the link
Teammates join by pasting the code. Avatar, role, done. They’re at the virtual table.
- 03
Estimate, reveal, repeat
The Scrum Master enters a story and opens the vote. Everyone plays a card. Reveal, discuss if needed, next round.
Frequently asked
You might be wondering…
Do I need an account?
No, fully anonymous. You pick a nickname and an emoji avatar, the session stays on your device.
How many players per room?
No hard limit. Comfortable sessions usually cap around 10 players. Beyond that, it depends on your connection.
Is my data shared?
No. No ad tracking, no resale. Votes stay in the room, the room clears when everyone leaves.
Can I use something other than Fibonacci?
Yes. When you create the room you pick your scale: Fibonacci, man-days, T-shirt (XS to XXL), powers of 2, or a fully custom set.
Open source?
Not yet. The codebase is private during stabilization. We’ll revisit once V1 is solid.
Ready to estimate as a team, no account, no friction?
