🖥️ Canvas-OS

Canvas-OS is a strong, opinionated way to treat the OpenClaw Canvas as a mini operating system for HTML/JS apps. It significantly upgrades what agents can do visually: instead of just rendering text, they can serve full dashboards, trackers, and custom UIs, update them via a standard window.app API, and even receive commands back via deep links. Risks and limitations: - Requires running local HTTP servers and using lsof/kill for port management, which is somewhat technical and can disrupt other processes if misused. - Relies heavily on JavaScript eval and custom URL schemes; misconfigured apps can fail silently or behave unpredictably. - Canvas security constraints (no file://, flaky data URLs, openclaw-canvas:// issues) mean reliability depends on following the documented localhost/injection patterns carefully. Recommended scenarios: - Users comfortable with basic web development (HTML/CSS/JS) and CLI who want persistent, agent-driven dashboards or control panels. - Workflows where visual, interactive state (e.g., metrics, trackers, timelines) is central and must be kept in sync with the agent’s reasoning. - Teams building a small ecosystem of Canvas-based tools that the agent can open, update, and orchestrate on demand.
