mabyko is a small studio making the things developers use every day. A coding font, a menu bar app, terminal tools, desktop GUIs. One tool for one problem.

The same skills in Codex, Claude Code and OpenCode. Bundle ID rules, Git safety hooks, docs sync — the things the team kept repeating, turned into skills.
Live →JetBrains Mono for Latin, D2Coding for Hangul, Nerd Fonts for icons. A coding font where Hangul is exactly two Latin cells wide. The headline on this page is set in it.
Live →While the AI thinks, meet a line from another developer. A message network that lives in the Claude Code spinner.
Live →Read diffs, follow commit history, and move between worktrees. A free, open-source macOS Git GUI that works with your existing repositories and Git configuration.
Pre-release →While you wipe the keyboard, keys are blocked and every screen goes black. Done wiping, the app is done too. A one-shot macOS utility that never lingers in the menu bar.
Pre-release →mise, by click. See installed runtimes, tools and plugins at a glance — upgrade, and roll back. A desktop GUI for mise with no commands to memorize. Command output stays visible.
Pre-release →Plug in, and your windows go back where they were. Nothing else moves. A macOS menu bar app that remembers window layouts per external display.
Pre-release →Narrow the problem instead of adding features. Plugback restores windows and nothing else, and asks for exactly one permission.
Code, design docs, decision records — all public. Building it yourself is the first install method.
We don't ship tools that break Hangul. The font's two-cell rule and the Korean README exist for that reason.
