Get Started

Built-in tools. Zero setup.

Stop juggling between your editor, browser, and terminal. DevBrowser brings them all together in one focused workspace.

Monaco Code Editor

The same editor that powers VS Code — syntax highlighting, IntelliSense, multi-file tabs, and format on save for HTML, CSS, JS, TS and more.

Live Browser Preview

A full Chromium browser pane with tabs, navigation controls, and auto-reload on save — see your changes the instant you hit Ctrl+S.

Project File Explorer

Full sidebar file tree with drag-to-move, right-click context menus for rename, duplicate, delete, and create. Works just like VS Code.

Integrated Terminal

Run npm scripts, Git commands, or any shell command right inside the app. No need to Alt+Tab to a separate terminal window.

Chrome Extensions

Install any unpacked Chrome extension — React DevTools, Redux DevTools, Vue DevTools — and use them in the built-in browser preview.

Responsive Preview Modes

Switch between desktop, tablet, and mobile viewports instantly. Test your layouts across screen sizes without leaving the app.

Git Status Panel

See staged, modified, and untracked files at a glance. Click any changed file to open it directly in the editor.

Find in Files

Global search across your entire project. Jump directly to matching lines in the editor with a single click.

Auto-Updater

Always stay on the latest version. DevBrowser silently checks for updates in the background and notifies you when one is ready.

One window. Everything.

The three-panel layout keeps your file tree, editor, and live preview side by side — no more alt-tabbing between apps.
