Chrome Extensions 拡張機能
Your browser,
supercharged.
We design fast, focused extensions that remove friction from the work you do most, built to Chrome's modern Manifest V3 standard: secure, private, and effortless to install. And when you want something more fun than functional, we build browser games too.
What we build 機能

Every extension is small, fast, and built to do one job perfectly, no bloat, no creepy permissions.
Productivity 生産性
One-click tools that shave minutes off the tasks you repeat all day, every day.
Automation 自動化
Fill forms, scrape data, trigger workflows, let the browser do the boring parts.
Privacy-first 守
Minimal permissions, no tracking, no bloat. Your data stays yours.
Custom for teams 特注
Internal tools tailored to your exact process, deployed across your whole team.
Integrations 連携
Connect the sites and SaaS tools you already use into one smooth flow.
Maintained 保守
We keep extensions current with Chrome updates so they never break on you.
We make games, too ゲーム
Beyond tools, we build playable browser games and gamified experiences, from quick mini-games and interactive widgets to polished web titles that run smoothly right in the browser.

Built right,
built to last.
Modern, standards-based engineering means your extension is fast today and still works tomorrow.
