# `inactivity_timeout`

End the session after this long with no traffic on its WebSocket.

**Use it for:** Freeing the thread quickly when a script dies (short), or giving a person or a slow step time to think (long), up to your plan's cap.

## Details

-   **Type:** `number | string`
-   **Default:** 120s
-   **Example:** `{"inactivity_timeout":"2m"}`

The timer resets on any protocol traffic in either direction. A number of seconds (`90`, `1.5`) or a string with a unit: `500ms`, `45s`, `10m`, `2h` (digits only, no spaces or decimals). Clamped to 1 s – 24 h. An unparseable value silently falls back to the default.

Up to 10 minutes on shared threads, 5 on Community and 24 h on dedicated; a longer value is cut to your plan's maximum. Idle minutes are billed like any others. A slow page load through a proxy can produce no traffic for a while, so keep it at 60 s or more. Never longer than the session's overall timeout.
