Agent-first local development

Sero is built around agent-driven workflows for local projects: chat, terminals, previews, plugins, and workspace context in one desktop shell.

Container-backed when available

Apple container-backed workspaces are the preferred runtime for isolation, tooling, and Linux parity, with host mode available as a reduced fallback.

Plugin-first extension model

Built-in and external plugins can add UI, Pi tools, runtime hooks, and provider integrations without changing the core app.
