Open source agentic AI,
top to bottom.

Arlo AI is a family of open-source projects for running AI agents on your own terms — a private agent runtime for your machine, a mobile client that talks straight to your provider, and the protocol layer that connects an agent to any frontend. No backend of ours in between. Ever.

Three projects, one idea

Every one of them free, MIT-licensed, and yours to run.

Arlo Rust

A private, local-first agent that speaks whichever interface you need — an interactive TUI, a one-shot CLI, or an embeddable library — and runs on macOS, Windows, and Linux. Your keys, your machine.

Arlo Lite

A React Native iOS app for talking to LLMs on the go. Bring your own API key and connect direct to your provider — no account, no subscription, nothing sitting in between.

React Native iOS BYO key

AG-UI Rust

An up-to-date Rust implementation of the AG-UI protocol — the standard, event-based interface that lets a web or app frontend drive Arlo Rust, wire-compatible with the TypeScript and Python SDKs.

How it fits together

Two independent paths to the same place — your own model, without a middleman.

Web · Desktop · Mobile frontends Whatever you want to build
AG-UI Rust The standard AG-UI interface
Arlo Rust Private, local agent runtime

or, straight from your pocket
Arlo Lite iOS, standalone
Your own LLM provider Connected direct, no backend

What we won't compromise on

The same four commitments across every project.

Bring your own keys

Your credentials stay on your machine and go straight to your provider. We never see them, because there is nowhere for them to go.

No backend, no subscription

There is no Arlo server to sign up for, no seat to pay for, and no account to create. You pay your model provider and nobody else.

Provider-agnostic

Anthropic, any OpenAI-compatible API, or a model server running on your own hardware. Point it wherever you like and switch whenever you like.

MIT licensed, in the open

Every project is developed in public under the MIT license. Read it, fork it, ship it in your own product — no strings.
