Free planning poker for Fibonacci story point estimation
Fibby is a free, browser-based planning poker
tool for agile teams sizing work in a sprint planning or backlog refinement
session. One person starts a room, shares the six-character code, and everyone
votes on the same story at the same time. No account, no install, no per-seat
licence — the room is live the moment it is created.
Votes stay hidden on the server until the whole table is revealed together, so
nobody anchors on the first number they see. Fibby then shows the average, the
median, the spread, and who is furthest from the group — because the point of the
exercise is the conversation the disagreement starts, not the number itself.
How it works
- Create a room and pick a deck — Fibonacci, modified Fibonacci, or T-shirt sizes.
- Share the room code with your team. They join as guests in one tap.
- Everyone picks a card. The table shows who has voted, never what they voted.
- Reveal. All cards flip at once and the statistics appear.
- Talk about the outliers, agree a number, and start the next story.
Why estimate with the Fibonacci sequence
A story point measures how big a piece of work is
compared to other work — effort, complexity, risk and unknowns combined. It is not
a disguised time estimate. Two developers who work at different speeds should still
agree a story is a 5, because 5 describes the story, not the person.
The deck runs 1, 2, 3, 5, 8, 13, 21, and the gaps widen as the numbers grow. That is
the whole idea: the bigger a piece of work, the less precisely anyone can size it, so
the deck stops offering precision that does not exist. A team can genuinely tell a 1
from a 2. Nobody can tell a 20 from a 21, and arguing about it wastes the meeting.
Common questions
- Is Fibby free?
-
Yes. Every feature is free and unlimited — rooms, participants, rounds and
decks. There is no paid tier and no trial. Running costs are covered by one
small ad on this page and by voluntary donations.
- Do I need an account to use it?
-
No. Everyone joins as a guest with just a display name. Accounts do not
exist for voting, because the moment a team needs this tool is mid-meeting,
with eight people waiting.
- Can other people see my vote before the reveal?
-
No. The server never sends a vote value to anyone until the round is
revealed. Other players see only that you have voted, not what you picked,
and that is enforced on the server rather than hidden in the interface.
- Which estimation decks are supported?
-
Fibonacci (1, 2, 3, 5, 8, 13, 21), modified Fibonacci with a half point, and
T-shirt sizes. Every deck also carries a "?" for "I need more information"
and a coffee card for "I need a break".
- Does it work for a remote team?
-
That is what it is built for. The table updates over a websocket, so every
vote, reveal and new round appears for everyone at the same moment without
a page refresh. It works over a screen share or with everyone on their own
device.
- What is planning poker?
-
Planning poker is a consensus estimation technique for agile teams. Everyone
privately picks a card representing the size of a user story, all cards are
revealed at once, and the team discusses any disagreement before agreeing a
final estimate. Hiding the votes until the reveal is what stops the loudest
or most senior voice setting the number for everyone.
