A cloud-shaped IDE,
on your own Mac.
Open a project, get a workspace with every tool an agent needs — terminal, AI chat, browser, code review, simulator — pre-wired. No VMs, no containers, no servers. Your shell, your files, your API keys. Native SwiftUI all the way down.
brew install --cask coursion-studio/tap/forge
macOS 15 (Sequoia) or later · Auto-updates via Sparkle · See the panes
Every pixel, native to macOS.
No Electron, no web views — real screenshots of the panes an agent works in. Split them, tab them, and every session keeps running as you switch workspaces.
Real terminals,
built for agents.
Persistent PTY terminals that keep running when you switch workspaces. Launch claude, Codex, Aider, or any CLI straight into your project — Forge detects what's installed and shows live activity.
- Persistent sessions
- Agent auto-detect
- Login-shell PATH
- Activity status
Chat with any model,
on your keys.
Talk to Anthropic or OpenAI with your own keys, stored in the Keychain — or run claude headless right in the pane. Streamed replies, inline tool calls, and multi-agent side-by-side in Compare.
- BYO API keys
- Streaming
- Claude Code provider
- Keychain only
Your dev server,
right in the pane.
A real WKWebView next to your terminal — preview the dev server, read docs, test what the agent just built. Page state survives workspace switches, so a reload never loses your place.
- Persistent pages
- Dev-server preview
- Per-leaf sessions
Review the diff
before you ship.
Git status, diffs, staging, commits, and PR lists without leaving the workspace. Ask AI to review the diff, then stage and commit inline once it's clean.
- Stage & commit
- gh PR list
- AI review
- Inline diffs
Talk to your
terminal.
Dictate straight into the focused terminal — adaptive silence detection auto-commits the transcript. Say "Command, …" to trigger a palette action hands-free, from anywhere via a global hotkey.
- Silence auto-commit
- Wake-word commands
- Global hotkey
And the rest of the drawer.
Every workspace can hold more than the flagship panes — here's a few of the others.
Every tool an agent needs.
Split, tab, and arrange panes per workspace. Sessions survive workspace switches — terminals keep running, chats keep streaming, pages stay loaded.

AI Chat
Talk to Anthropic or OpenAI models with your own keys, stored in the Keychain. Compare multiple agents side-by-side in the Compare pane.

Every version, every download.
Live count, every channel — site and in-app updates.
Native. Local. Yours.
Cloud agent workspaces, minus the cloud.
100% native SwiftUI
No Electron. No web views pretending to be apps. Feels like macOS because it is macOS.
Fully local
No VMs, no containers, no accounts. Shell runs on your Mac, files live in your folders. AI is optional and runs on your own keys.
Workspaces that persist
Split panes, tab groups, per-workspace accents. Switch projects with ⌘1–⌘9 — everything keeps running.
Auto-updates
Sparkle-signed updates ship over the air. Apple-notarized DMGs, EdDSA-verified — no App Store middleman.
