Deck - VS Code extension for working with multiple repos, worktrees and coding agents

Hi all — I built a VS Code extension called Deck and have been using it daily for about a month.

I run Claude Code and Codex across a bunch of git worktrees at once. I tried Superset and cmux first, but they're separate apps and constantly switching out of VS Code was killing me. Plain tmux kept the terminals alive, but the UX wasn't great: terminals stuck in the bottom panel, no Ctrl+Tab between sessions, and every reboot I'd get logged out of all my agent sessions.

So I built Deck. It adds a Repositories & Worktrees tree to the secondary sidebar (repo → worktree → terminals) — same idea as Superset/cmux, but inside VS Code so I'm not switching apps.

Persistent terminals, one per worktree, opened as editor tabs (Ctrl+Tab between them). They're tmux-backed but you never touch tmux. Close a tab and reopen it, or switch worktree (which reloads the window), and whatever's running keeps running.

A few more things it does:

• The same terminal can be open in two windows at once, both live views of one session.
• Survives reboot — terminals come back with their scrollback, and Claude Code / Codex sessions resume automatically, so not resuming every chat.
• Agent status on the tree row — working / needs input / done, labeled with what each agent is working on, with optional notifications when one needs you.
• One-click launchers — save a command (your agent with its usual flags, a bootstrap script) and optionally auto-run it when a worktree is created.

MIT-licensed, no telemetry. Requires VS Code 1.110+ and tmux 3.1+. Status and session-resume currently support Claude Code and Codex; the terminals run anything, and if you'd like another agent supported, open an issue.

Still rough around the edges and there's more coming, but it's been working well for me.

Ok.
