Terminal mode is a quick-start serial terminal — no account, no setup. Just open the page and connect a device. The free plan gives you the full pipeline editor: Lua transforms, CLI connections, and multi-node pipelines.
Free plan sessions have a cumulative 60-minute run time. Terminal mode has no time limit since nothing is stored server-side.
Chrome and Edge — any browser that supports the WebSerial API. Firefox and Safari don't support WebSerial yet. The CLI bridge works regardless of browser.
