One window for every app you run. Multidex hosts modular apps, tools & skills on the
embedded Dexus engine, wires them into one App API, and puts an AI agent at the deck
that builds new modules — and drives the ones you have. In the neon window or straight in your
terminal. Shared peer-to-peer — signed, verified, yours.
Every capability is an isolated module you command from one deck — install, launch, build, wire together and distribute without leaving the window.
Apps · Tools · Skills
Every module runs isolated on the embedded Dexus engine — own port, logs and lifecycle — and lands in one of three grades: full apps, atomic tools and multi-step skills.

AI agent at the deck
Ask for “a real-time stock market monitor” — the agent writes, signs and installs it as a live module. Then keep asking: it answers, operates your modules and calls their capabilities.

One App API
Modules declare tools, events and skills once — in the manifest. The agent, neighbour apps and paired peers call them through one bus: schema-checked, permissioned, journaled.
A built-in MCP gateway projects every declared capability to external agents — Claude, IDEs, scripts — behind a Bearer token. Destructive calls still stop for a human yes.

GUI or terminal — same deck
One binary, four modes. Open the neon window, or add --console for a full pseudographic workspace — Library, agent chat, sharing and settings in plain text. --server runs headless, --daemon detaches.
The deck agent thinks on the built-in local engine out of the box — or your API provider, or a full coding agent: Claude Code, Codex, Cursor. CLI agents run in the terminal, GUI agents plug in via Multigen.

Dex store & P2P
Publish modules as signed .dex packages — one package carries Windows, Linux and macOS binaries — pull apps from other instances, or serve your own catalog.
Ngrok tunnel
Expose your catalog to the internet with a built-in tunnel — remote instances install your shared apps in one click.
20 languages · 3 themes
Translation packs baked into the binary — switch instantly. Three shells: quardex neon, matte dark, calm light. Modules follow the theme live.
Signed & safe
Every package is Ed25519-signed and SHA-256 verified on install. Releases are immutable, trust keys are baked into the binary. All of it enforced in the compiled backend.

Describe it. Ship it. Drive it.
Chat with the deck agent right inside Multidex — in the window or the terminal. Say what you want — the agent generates a complete module, signs and installs it, streaming every file into the chat as a live, collapsible card. Already installed? It calls that module's API instead: answer first, operate second, build only when asked.

All your apps, one Library
The Library holds every installed module — icon, live status and port — grouped into Apps, Tools and Skills. Launch, configure and remove them — or open any app right inside the nexus.

Declared once. Called from anywhere
A module ships its API in the manifest — tools, events and multi-step skills. Multidex turns that one declaration into a control surface for every caller: the deck agent, neighbour modules, the terminal workspace, external agents over MCP, even paired peers.
App-to-app calls under per-capability permissions
Declarative skills chain modules into one command
Destructive ops wait on a plan and your explicit yes

An engine, not a launcher
Under the deck runs Dexus — a process engine that supervises every module: spawn, port allocation, health, logs, autostart. The same engine sits behind the window, the terminal and the headless server. You see everything. You control everything.
Isolated process per module, own port & PID
Start, stop and inspect logs in real time
Native binaries or pure web modules
Per-app operation queues — installs, updates and agent edits never collide

One flag from window to terminal
The same binary that opens the neon window renders the whole nexus as pseudographics: pass --console and the deck is right there in your terminal — Library, agent chat, sharing, settings. Pseudographic boot logo included.
Full GUI parity: install .dex, chat with the agent, publish & pull, trust prompts with key fingerprints
--server runs headless, --daemon detaches — same engine, same API
Modules can ship their own CLI — Enter hands them the terminal, q hands it back
Every action runs through the same compiled, signed backend as the GUI
