What you get

Built for quick starts and steady flow

Insight

Kodo's smart assistant - powered by .kox extensions - predicts code, highlights unused code, and detects errors. Fully customizable per file type from a dedicated settings panel.

[]

Marketplace + Local Extensions

Browse languages, themes, and compilers inside the app, or drop in your own .kox files. Extensions can now add UI elements and C# code.

►

Build / Run

Compile and run your project with one click. Specify custom commands or link batch scripts via the dropdown - compilers on your system are picked up automatically.

□

Clean Workspace

Folders, a resizable file explorer, recent files, and tab restore in an interface that stays out of the way. The file tree updates automatically when files change outside Kodo.

⌘

Editing Quality-of-Life

Customizable keybinds, a built-in colour picker, overhauled find/search (file, project-wide, by name), autosave, and expanded right-click menus across the editor, tabs, and terminal.

Built-In Extras

Themes, an embedded terminal, optional Discord Rich Presence, and a Performance Mode that debounces searches and disables heavy panels when you need speed.

⟳

Background Auto-Updates

Kodo checks GitHub releases on its own and keeps both the editor and your installed extensions current without getting in your way.

▣

Image Preview

Open image files right inside the editor and zoom in without switching to another app.

◉

Privacy by Default

No accounts, and anonymous usage analytics stay off unless you opt in - Kodo asks once and never tracks silently.

Extensions

Language support and themes that fit your stack

Kodo loads syntax highlighting, themes, compilers, and now UI and C# code through `.kox` extensions, with marketplace browsing built right into the app. Open a file, install what you need, and let Kodo match the right highlighting and Insight suggestions automatically.

Browse official extensions

Language support adds highlighting, Insight predictions, and build detection for covered files.
