Localix Studio

The Agentic Development Environment

An AI agent and its subagents work with you in one desktop app: your editor, terminals and browser. Any model, or run one on your own computer.

Subagents An agent hands side tasks to subagents that work in parallel and report back. Subagents →	A fast Browser Agents drive any page step by step and check the result. The Browser →	Decision models Small, cheap models make the quick calls across the app. Decision models →
Mini apps, built by the agent Describe one to the agent, with the authoring plugin from the Localix marketplace: a meal log from photos, a dashboard, a game, wired to the agent, models and embeddings. Build a mini app →	Your coding agents Claude Code, Codex, Gemini CLI and more, linked to your chats. External agents →	Any model Sign in or bring a key, or run models on this computer. Providers → · Local models →
Mini apps as Mac apps Install a mini app as its own app: a Dock icon, a window of its own, and the agent beside it. Mini apps as Mac apps →

Plugins and mini apps

Plugins are Claude Code's format and load as they are: /plugin install owner/repo, with skills, commands, agents, hooks, MCP and language servers working as in Claude Code (compatibility). Mini apps are Localix's own: screens, a backend and agent tools. Install them from the Store, or have the agent build one (mini apps, build with the agent). Localix itself ships none: its own mini apps and plugins are in the Localix marketplace.

On this computer

• Local models. Settings → Models picks Gemma 4 at the size your machine runs well, with a Fastest–Smartest slider, and adds any GGUF model by its Hugging Face id. Nothing you send them leaves the computer. See local models.
• Search by meaning. On by default: an embedding model downloads in the background, and search then finds chats, messages, skills, plugins, MCP servers and agents by what they mean, in any language. See semantic search.

Download

• macOS, Apple silicon: Localix-macos-arm64.dmg from the latest release, signed and notarized
• macOS Intel, Linux, Windows: no installer yet, run from source

Each release lists checksums in SHA256SUMS.txt.

Run from source

For the desktop app, install Bun 1.4.4, a Rust toolchain, and your platform's Tauri prerequisites.

git clone https://github.com/localixai/localix-studio.git
cd localix
bun install --frozen-lockfile
bun run dev

Connect a provider through the model picker — or download a model in Settings → Models to run one on this computer — choose a model, and start a conversation.

To use the browser workspace instead of the desktop shell:

bun run dev:web

Open http://localhost:5050 after the servers start; the API listens on 127.0.0.1:5051. This uses a separate, git-ignored database at .data/dev/localix.db.

See installation for platform requirements and local builds, and troubleshooting for startup problems.
