Errand is open source, powered by Runta Cloud Agents.
Explore the code, build it yourself, or help shape what comes next.
Errand is a macOS app for working with persistent AI agents. Each agent has a conversation and its own Runta cloud computer, with files and tools that stay in its workspace.
A Mac with Apple Silicon running macOS 13 or later, a Runta account, and a model provider configured for your agents. Download the app, sign in, and create your first teammate.
The desktop app is a window into the cloud workspace. Closing it does not delete your agents, conversations, or files. Reopen Errand to reconnect and retrieve their latest work.
Errand’s source code is open and the app is available to download. Cloud runtime and model usage are separate and depend on your Runta and provider setup.
The interactive preview uses sample conversations and documents. It does not connect to an AI service or send messages outside this page. Download Errand to work with real agents.
Your next teammate is one message away.
