v0.1 · your subscriptions, your machine

Build the thing
that builds.

Spawn Claude Code, Codex, Gemini, or any CLI agent installed on your Mac, side by side in real terminals. Let a Manager chat route tasks and answer waiting panes while you stay focused on what only you can decide.

Social proof

Trusted by at least one
dev in San Francisco.

Some of them even left their Warp subscription to prove it.

Bring your own sub

Mandeck doesn't resell tokens. Plug in Claude Code, Codex, Gemini, or OpenCode with the credentials you already have. We orchestrate them, you keep your plan. No middleman key, no markup, no cloud hop.

ship the login fix, then have someone pick up the flaky test
On it. Pane #1 is fixing the auth token issue. I'll route the flaky test to a fresh Codex instance once that's merged.

⌘I Manager

An orchestrator that delegates.

The Manager chat never writes code itself. It spawns agents, routes tasks between panes, reads context from every running session, and escalates to you only when a human is actually needed, not when it just wants confirmation.

Spawns and routes agents by task type, not by you dragging splits
Answers waiting panes by your standing rules, no interruptions for obvious questions
Badges you only when a decision requires a human
Every session resumable with ⌘K, full context intact

AppKit · libghostty

Native Swift, not a web wrapper.

Real terminals.
Powered by libghostty, the same terminal engine as Ghostty. Every keystroke reaches the pty directly. No xterm.js, no DOM event queue, no rendering latency.
Instant.
82 MB installed. 0.4 second cold start. Measured, not estimated. Other tools in this category take 5 seconds and 400 MB to show a splash screen.
Local-first.
Sessions, keys, and logs never leave your Mac. No cloud relay, no telemetry, nothing to trust us with. Auto-updates ship signed via Sparkle, and you read the changelog before they install.
