How to use

  1. 1

    Enter participant names

    Type or paste the names of all tournament participants into the text box, one name per line. The counter shows how many players have been entered (2–32 supported).

  2. 2

    Choose seeding method

    Select 'Random' to shuffle participants into random bracket positions, or 'Seeded' to place them in the order you entered — first name gets the top seed.

  3. 3

    Generate and play the bracket

    Click Generate Bracket to build the elimination bracket. Click a participant's name in any match to advance them as the winner. BYE opponents advance automatically. The final winner is highlighted with a trophy.

  4. 4

    Copy or restart

    Use Copy Results to export the bracket as formatted text. Reset Bracket clears all winners so you can replay, or start a New Tournament with different participants.

Frequently asked questions

How many participants can the bracket handle?
The bracket supports 2 to 32 participants. If the number isn't a power of 2, BYE entries are added automatically to fill the bracket evenly.
What does seeded vs random mean?
Seeded keeps participants in the exact order you entered them — the first name is the #1 seed and gets the top bracket position. Random shuffles all names into random positions before building the bracket.
How do BYE entries work?
When the participant count isn't a power of 2, the bracket adds BYE slots to fill the gaps. Any player matched against a BYE automatically advances to the next round without needing to click.
Can I undo a winner selection?
Use the Reset Bracket button to clear all winners and start the bracket over from the first round. This keeps the same participants and seeding.
Is my data stored or sent anywhere?
No. The entire tool runs in your browser. Participant names and bracket data are never uploaded to a server or stored anywhere outside your current session.

Build single-elimination tournament brackets in seconds. Paste or type

participant names (one per line), choose random or seeded ordering, and

generate a full bracket that supports 2–32 players. If the player count

isn't a power of 2, BYE slots are added automatically so every round is

balanced. Click any participant's name to advance them as the match

winner — the bracket updates in real time, flowing winners into the

next round until a champion is crowned. Round headers adapt to bracket

size (Round 1, Quarterfinals, Semifinals, Final). When the tournament

is complete, copy the full results as formatted text to share in Discord,

a spreadsheet, or anywhere else. Everything runs locally in your browser

— no accounts, no uploads, completely private.
