Projects that sleep
Every open project is a small record until you switch to it. File tree, git state and editor views exist only for the project on screen.

The workspace for AI coding agents.
Built to stay light.
Run Claude Code, Codex and OpenCode side by side across all your projects in one native app that starts at 17 MB, not 1 GB.
Free · Apple silicon · macOS 14 or later
Works with the agents you already use
- Claude Code
- Codex
- OpenCode
From folder to agent in three steps
01
Add your projects
Open any folder, as many as you like. Each one becomes a tab. Inactive projects cost under 1 MB.
02
Start an agent
Pick Claude, Codex or OpenCode for a project. The real terminal UI opens in a tab next to your files.
03
Switch and supervise
Jump between repos with ⌘1 … ⌘9. Badges show which agent finished or needs you. Review changes in the gutter.
Small on purpose
Most of your RAM should go to your agents and your builds, not your editor. Measured on a 16 GB MacBook with the release build.
17 MBRAM at launch
No Electron. No Chromium. One native process.
0.8 MBper idle project
Ten projects open cost about 29 MB in total.
16 msproject switch (p95)
Switch between repos with ⌘1 … ⌘9.
0memory leaks
Checked with leaks after every benchmark run.
One run, release build, 16 GB MacBook. Agent CLIs such as claude are separate processes (roughly 200 to 450 MB each) and are not counted above. Full method in the repo's benchmarks doc.
Everything you need, nothing you do not
A focused set of tools for working with agents across many repos.

Real agent terminals
Claude Code, Codex and OpenCode run as their real terminal UIs in tabs. No wrapper chat. You get every feature they ship.
⏾
Agents you can leave
Idle agents in background projects can suspend and resume later, so a stack of sessions does not eat your RAM.
⑂
Git at a glance
Changed-line markers in the gutter, a source control panel and branch status. Updates follow your agents as they edit files.
{ }
A fast native editor
Syntax highlighting, line numbers, find, wrap and quick file switching. Files reload when an agent changes them.
⚙
Opt-in agents
Enable only the agents you use in Settings. A disabled agent adds no tab, no menu item and no memory.
One place for every agent
Open a Claude, Codex or OpenCode session per project. Each runs as its real terminal UI in a tab, next to your files. Close the app and pick up the same session later.
- Real TUIs inside tabs, with full colour and mouse support
- Badges tell you when an agent finishes or needs input
- Turn agents on or off in Settings. Off means zero cost
Claude Code
Resumes by session id
Codex
Resumes your last session
OpenCode
Continues where you stopped
A closer look
A real shell under every project, and one switch per agent.
How a project lives
Every project moves through four states. Only the one on screen is fully built.
01 · < 1 MB
Dormant
Only a small record: path, open files, layout. No views, no git, no processes.
02 · on screen
Active
File tree, git status and editor are built when you switch in, in about 16 ms.
03 · agent running
Background
Terminals keep running while you work elsewhere. Their views are detached and cost no drawing.
04 · resume later
Suspended
An idle agent can stop and come back with its session, so old work does not hold your RAM.
Made for how you work
Many repos at once
Keep a frontend, an API and a docs site open and hop between them without waiting.
Long agent runs
Start a task, switch away and get a badge when the agent finishes or asks for input.
Small laptops
Leave RAM for builds, simulators and browsers instead of a heavy editor.
Trying several agents
Run Claude, Codex and OpenCode on the same project and compare their diffs.

Get Native IDE
Free for macOS. Open it, add a project folder and start an agent.
First launch: right-click the app and choose Open. Builds are not notarized yet.
Questions
Is it really that light?
The app itself uses about 17 MB when it starts and under 1 MB for each inactive project. Agent CLIs such as claude run as separate processes, and their memory is not part of that number.
Which agents does it support?
Claude Code, Codex and OpenCode. Claude is on by default. Turn Codex and OpenCode on in Settings (⌘,) when you want them.
Do I need accounts or API keys here?
No. Native IDE launches the CLIs you already installed and signed in to. It never sees or stores your keys.
Is my code sent anywhere?
Native IDE has no analytics, telemetry or network code of its own. Your code stays on your Mac. Each agent CLI talks to its own provider, the same as in any terminal.
What happens to a session when I close the app?
Native IDE saves your projects, open files and layout. Claude sessions resume by session id when you start the agent again. Nothing starts on its own at launch.
Which macOS versions work?
Native IDE is a native macOS app for Apple silicon Macs. It is built with Swift and AppKit.
Why does macOS warn me on first open?
Builds are ad-hoc signed for now and not notarized. Right-click the app and choose Open the first time.
