Aether is a desktop workspace written in Rust. It drives the agent CLIs you already use and keeps their Git worktrees, terminals and files in the same window, so you can run five agents without losing track of any of them.
macOS 12+Linux x86_64 and aarch64Source opens soon
Aether does not ship a model or resell tokens. Each agent chat is a live session of a real CLI, started in your project folder, so your subscription, settings, skills and MCP servers come with it.
| Provider | How Aether talks to it |
|---|---|
| Claude Code | claude -p with stream-json over stdio |
| Codex | codex app-server |
| OpenCode | one shared opencode serve and its event stream |
| Pi | pi --mode rpc, NDJSON over stdio |
| Antigravity | agy -p |
| OpenRouter | HTTP API, for direct chats that need no project |
Turn on Lead for a chat and its CLI gets five tools over MCP. The lead can start children on other providers, talk to them and stop them. Each child’s result comes back to the lead on its own, so nothing polls.
aether mcp and wired into the CLI at launch. No config file to write.max_children in settings goes from 1 to 50.Split a session right or down, float it over the workspace, or detach it into its own desktop window. A moved session keeps its draft, scroll position, running turn and pending questions.
Tabbed keeps chats in top tabs. Sidebar docks the Agent, Explorer, Terminal and Browser panel beside the chat and lets it collapse. Split keeps that panel docked. Layouts, window positions and drafts restore when you reopen the app.
On Linux, ⌘ is Ctrl and ⌥ is Alt.
Review what an agent changed, run what it wrote and open the file it mentioned without switching apps.
Give a chat its own worktree from the composer. Aether creates an aether/<slug>branch from the prompt on first send, never reusing a branch or folder. Sidebar rows show the branch, changed files and ahead or behind counts. Stage, diff, commit and push from the Changes panel.
A global terminal that survives page changes, plus one for each project or worktree. tmux and Neovim keep running with the drawer closed. Ctrl` toggles it.
File tree, tabs, Quick Open ⌘P and workspace search⌘⇧F. A file path in an agent reply opens at its line.
Aether is one Rust binary drawn with GPUI, the GPU-rendered UI framework behind the Zed editor. No Electron. Agents run as ordinary processes on your machine.
aether.db, a SQLite file in your config folder. Attachments are copied next to it..deb for Linux, each with a SHA-256 checksum.No. Agent chats run the CLIs you have installed and signed in to, under your own subscriptions. The only API Aether calls itself is OpenRouter, for direct chats, with a key you provide, stored in the system keychain.
macOS 12 or newer on Apple Silicon and Intel, and Linux on x86_64 and aarch64 with glibc. Linux builds use GTK 3 and WebKitGTK 4.1 for the browser panel and need a Vulkan driver. There is no Windows build.
Yes, for Claude Code, Pi and OpenCode. The Agents page finds them, shows whether they are working, waiting or idle, and can open them in Aether or stop them after you confirm.
No. Turn on Lead for a chat and Aether passes its MCP server to that CLI at launch. Antigravity is the one exception: it needs a one-time global registration, which Aether offers to run the first time a lead starts.
The source goes up on GitHub shortly. The docs already cover how Aether is put together, how to build it and how to send a change.
