Tournament Bracket Maker: single-elimination brackets for up to 1,024 players, with seeding and byes worked out for you

Paste a list of names, one per line, and the Tournament Bracket Maker on Omikuji Tools draws a single-elimination bracket. Click a match card to pick the winner. It is meant for the kind of event where someone usually ends up drawing the bracket by hand: a table tennis cup at the office, a school sports day, a game night.

Tournament Bracket Maker: 11 players in a 16-slot bracket, with byes given to the top seeds

Byes and seeds without the arithmetic

The awkward part of a bracket is a player count that is not a power of two. The tool rounds up to the next bracket size and fills the gap with byes: in the screenshot, 11 players go into 16 slots and five players skip the first round. Who gets those byes is decided by the standard seeding order (1 meets 16, 8 meets 9, and so on down the bracket), so the players you list first are the seeds, get the byes, and are kept apart until the late rounds. If you would rather not seed anyone, the participant editor has a shuffle button, which uses the browser's cryptographic random generator.

The bracket lives in the link

There is no account and no database behind it. The whole state, names and results so far, is encoded into the URL after the #, so reloading keeps your progress and anyone with the link sees the same bracket. The share button (or the S key) turns that long link into a short one; that is the only moment anything is sent to a server, and only because you asked for it.

Features

  • Up to 1,024 participants; byes placed automatically
  • Seeds follow input order; shuffle available
  • Undo (Z), zoom, and fit-to-screen (0) for large brackets
  • Share progress with a link; print with the browser's print function
  • Light and dark themes; works on phones and desktop

👉 Tournament Bracket Maker — available in 12 languages.

Amidakuji (Ghost Leg) maker: a fair random pairing tool for up to 200 people, entirely in the browser

Image
Amidakuji is the Japanese ladder lottery: names go along the top, prizes or roles along the bottom, and each person traces a path down a ladder with random rungs. Every name lands on exactly one result, and nobody can predict it. Offices in Japan use it for seating, task assignment and drawing lots. I built a browser version that works for up to 200 people. How it works Enter names (and optionally results). Paste a column from a spreadsheet and the rows fill in automatically; tab-separated "name → result" pairs work too. Press Draw and watch each path animate down the ladder, or reveal them one at a time. Nothing is sent to a server. The whole lottery (names, results, and the random seed for the rungs) lives in the URL after the # , so you can hand the link to others and they will open exactly the same ladder. Cheat prevention : turn it on and the results stay hidden until every path has been traced. Redrawing changes the seed, so a new link means a new draw. Share...

omikuji.dev: free browser-based tools, puzzle games and reference sites made in Japan

Image
This blog is where I post news about the sites I build and run under omikuji.dev . Everything is free, needs no sign-up, and wherever possible runs entirely in your browser so that nothing you type or drop into a page ever leaves your device. What is there Omikuji Tools — about 130 small web tools: timers and clocks, a ladder lottery, PDF and audio converters, text converters, network checks (SSL certificate, DNS, IP address), calculators and print templates. Most are available in 12 languages. omikuji games — 105 browser games (puzzles, logic, arcade, brain training, play against the CPU, and games for small children). Everyone gets the same daily puzzle and can post to that day's leaderboard. Japanese only for now. Reference sites — a kaomoji dictionary (59,000 Japanese text faces), an emoji dictionary, a dictionary for the Japanese word game shiritori , traditional colors of the world with sources, and a guide to etiquette mistakes travelers make abroad. These are in Ja...

Hakarasenai: a Firefox extension that only stops Google Analytics from measuring you

Image
The second piece of software I publish is Hakarasenai , a Firefox extension for desktop and Android. The name means "won't let it measure", and that is the entire feature list: it stops Google Analytics from measuring you. Free, MIT licensed, on addons.mozilla.org (v1.2.0). Why it exists Google ships an official "Google Analytics Opt-out Add-on", and there is a Firefox build of it. The trouble is how it works: it injects a <script> element into the page, and Firefox, like Safari, applies the page's own Content Security Policy to content scripts. On any site with a strict CSP the injection is blocked and the opt-out quietly does nothing. Nothing tells you it failed, which is the worst failure mode a privacy tool can have. I ran into this while trying to keep my own visits out of the GA4 properties of my sites, and wrote this instead. Two layers It tells the Google Analytics code on the page that you have opted out, using the same official hook...
