# `proxy_updatable`

Kept for compatibility: every session's proxy can now be swapped without it.

**Use it for:** Long sessions that must change IP without losing state: rotate after a block, switch country mid-flow, or move a logged-in session to a fresh exit.

**Browsers:** [Google Chrome](https://cdpfleet.com/docs/browsers/chrome#opt-proxy_updatable), [Microsoft Edge](https://cdpfleet.com/docs/browsers/edge#opt-proxy_updatable), [Brave](https://cdpfleet.com/docs/browsers/brave#opt-proxy_updatable), [Opera](https://cdpfleet.com/docs/browsers/opera#opt-proxy_updatable), [Naver Whale](https://cdpfleet.com/docs/browsers/whale#opt-proxy_updatable), [Yandex Browser](https://cdpfleet.com/docs/browsers/yandex#opt-proxy_updatable), [Chromium](https://cdpfleet.com/docs/browsers/chromium#opt-proxy_updatable), [Patchright](https://cdpfleet.com/docs/browsers/patchright#opt-proxy_updatable), [Rebrowser](https://cdpfleet.com/docs/browsers/rebrowser#opt-proxy_updatable), [Camoufox](https://cdpfleet.com/docs/browsers/camoufox#opt-proxy_updatable), [Firefox](https://cdpfleet.com/docs/browsers/firefox#opt-proxy_updatable), [WebKit](https://cdpfleet.com/docs/browsers/webkit#opt-proxy_updatable).

## Details

-   **Type:** `boolean`
-   **Default:** false
-   **Example:** `{"proxy_updatable":true}`

Every session's `proxy` / `proxy_rules` can be changed while it runs (see Proxies → live swap), with or without this flag: measured 2026-10-26 on Chromium and WebKit, a US exit moved to Germany on the next new connection. Older code that sends `true` keeps working.

Has no effect without a `proxy`.
