NEW · IDE4 LITE FOR WINDOWS

Open a folder.
Start an agent.

IDE4 Lite is the small, fast way to run Codex and Claude Code side by side. Each pane works in a folder you choose, like a terminal opened there. Nothing to set up, the same free IDE4 account, and a download of about 100 MB.

IDE4 Lite with three colored agent panes: two smaller panes on the left and a larger one on the right, each working in its own folder. — Captured in IDE4 Lite 0.4.25 · Sample folders & activityA closer look

WHAT IT IS

Just the agents.
Just a folder.

The part of IDE4 you reach for most,
with everything else out of the way.

A pane is a folder

Point a pane at any folder and give it a task. No projects, workspaces or teams to create first. Add another pane by hovering the right edge.

Arrange it your way

Drag a pane's grip to dock it beside, above or below another. Drag the gutters to resize in both directions. Two small on the left, one big on the right, if that's how you work.

Your looks

Dark, light, and two see-through looks that leave only your panes over the desktop. Each pane has its own colour and how strongly it shows. Click the pane's logo to switch.

02 / A CLOSER LOOK

Small app,
view by view.

01 / PANES & LAYOUT

A folder each,
arranged your way.

Every pane works in its own folder with its own agent. Lay them out however the work needs.

02 / LOOKS

Dark, light,
or see-through.

Four looks on one click: dark, light, and both again with the window's ground gone so only your panes show over the desktop.

Light

The same panes and colours in light mode. Click any pane's logo to move to the next look, or pick one in pane settings.

LITE OR IDE4?

Same agents. Same account.
Less around them.

Lite is IDE4's agent panes on their own. IDE4 adds voice, projects, teams and more. Both are free, and both use the coding subscriptions you already have.

04 / FAQ

Questions
about Lite.

Setup, updates, and what stays in the full app.

Do I need IDE4 to use IDE4 Lite?+

No. Lite is its own Windows app with its own installer. It signs in with the same free IDE4 account, so if you already have one there is nothing new to create.

Can I install both?+

Yes. IDE4 and IDE4 Lite install side by side, each with its own data. Open whichever fits the moment: Lite for a quick pane in a folder, IDE4 for projects, teams and voice.

How does Lite update?+

Lite checks its own GitHub releases, downloads a new version in the background, and asks you when to restart. Nothing is installed until you choose to.

What is not in Lite?+

Voice dictation and local transcription, projects and workspaces, teams, workflows, connected repositories and the file editor. Those are in IDE4, which is why its installer is much larger.

Where do my files and conversations live?+

On your computer. Lite works in the folders you choose and keeps its conversations locally. Your chosen AI provider processes the prompts you send under your own Codex or Claude Code account.
