Born in the terminal, flexible everywhere ​

Mold began as a single-binary command-line tool and the CLI remains its stable foundation. Every core workflow can be run by a person, composed in a shell pipeline, automated in CI, or called by an agent. mold serve, REST/SSE, MCP, and the desktop and web surfaces all extend that same engine and contract; the iPhone and Android apps use the same contract as remote-only clients.

Mold Studio for desktop ​

Create locally on Apple Silicon or NVIDIA, or connect every Mold machine you use. On a Mac, download Mold Studio — the native macOS app, with mold's Metal engine built in, a merged multi-machine Library, queues, models, and machines in one window. On Windows and Linux the desktop app keeps generation, a unified multi-host Library, model discovery, live downloads, queues, telemetry, and RunPod in one focused workspace; the same app remains available as the legacy Mac download for Macs that cannot run macOS 26.
