| description: "Customize Chrome behavior on Kernel browsers using Chrome enterprise policies" | ||
| --- | ||
|
|
||
| Kernel browsers accept an optional `chrome_policy` object that lets you apply [Chrome enterprise policies](https://chromeenterprise.google/policies/) to the browser at launch. Use this to control startup behavior, default homepages, bookmarks, download UI, notifications, and other browser-level settings. | ||
|
|
||
| `chrome_policy` is supported on: | ||
|
|
||
| - [`browsers.create()`](/api-reference/browsers/create-a-browser#body-chrome-policy) — on-demand browser sessions | ||
| - [`browserPools.create()`](/api-reference/browser-pools/create-a-browser-pool#body-chrome-policy) and [`browserPools.update()`](/api-reference/browser-pools/update-a-browser-pool#body-chrome-policy) — reserved browser pools | ||
|
|
||
| Keys are Chrome policy names and values are the corresponding settings. | ||
|
|
||
| ## On-demand browsers | ||
|
|
||
| Pass `chrome_policy` when creating an on-demand browser. The policy is applied at session creation time. | ||
|
|
||
| <CodeGroup> | ||
| ```typescript Typescript/Javascript | ||
| import Kernel from '@onkernel/sdk'; | ||
|
|
||
| const kernel = new Kernel(); | ||
|
|
||
| const kernelBrowser = await kernel.browsers.create({ | ||
| chrome_policy: { | ||
| HomepageLocation: "https://kernel.sh", | ||
| HomepageIsNewTabPage: false, | ||
| ShowHomeButton: true, | ||
| DownloadBubbleEnabled: false, | ||
| }, | ||
| }); | ||
| ``` | ||
|
|
||
| ```python Python | ||
| from kernel import Kernel | ||
|
|
||
| kernel = Kernel() | ||
|
|
||
| kernel_browser = kernel.browsers.create( | ||
| chrome_policy={ | ||
| "HomepageLocation": "https://kernel.sh", | ||
| "HomepageIsNewTabPage": False, | ||
| "ShowHomeButton": True, | ||
| "DownloadBubbleEnabled": False, | ||
| }, | ||
| ) | ||
| ``` | ||
| </CodeGroup> | ||
|
|
||
| The policy is echoed on `GET /browsers/{id}` and `GET /browsers` responses so you can verify what was applied. | ||
|
|
||
| ## Reserved browser pools | ||
|
|
||
| Pass `chrome_policy` when [creating](/browsers/pools/overview#create-a-pool-of-reserved-browsers) or [updating](/browsers/pools/overview#update-a-pool) a pool. Every browser in the pool launches with the policy applied. See [Custom chrome policies on pools](/browsers/pools/policy-json) for the pool-specific update flow (including `discard_all_idle`). | ||
|
|
||
| <CodeGroup> | ||
| ```typescript Typescript/Javascript | ||
| import Kernel from '@onkernel/sdk'; | ||
|
|
||
| const kernel = new Kernel(); | ||
|
|
||
| const pool = await kernel.browserPools.create({ | ||
| name: "my-pool", | ||
| size: 5, | ||
| chrome_policy: { | ||
| DownloadBubbleEnabled: false, | ||
| HomepageLocation: "https://example.com", | ||
| }, | ||
| }); | ||
| ``` | ||
|
|
||
| ```python Python | ||
| from kernel import Kernel | ||
|
|
||
| kernel = Kernel() | ||
|
|
||
| pool = kernel.browser_pools.create( | ||
| name="my-pool", | ||
| size=5, | ||
| chrome_policy={ | ||
| "DownloadBubbleEnabled": False, | ||
| "HomepageLocation": "https://example.com", | ||
| }, | ||
| ) | ||
| ``` | ||
| </CodeGroup> | ||
|
|
||
| ## Example policies | ||
|
|
||
| | Policy | Type | Description | | ||
| | --- | --- | --- | | ||
| | `HomepageLocation` | `string` | URL loaded when clicking the home button | | ||
| | `HomepageIsNewTabPage` | `boolean` | When `false`, the home button navigates to `HomepageLocation` instead of the new tab page | | ||
| | `ShowHomeButton` | `boolean` | Shows the home button in the toolbar | | ||
| | `NewTabPageLocation` | `string` | URL shown when opening a new tab | | ||
| | `RestoreOnStartup` | `integer` | Set to `4` to open a specific list of URLs on browser startup | | ||
| | `RestoreOnStartupURLs` | `string[]` | URLs to open when the browser starts. Requires `RestoreOnStartup` set to `4` | | ||
| | `BookmarkBarEnabled` | `boolean` | Shows the bookmark bar | | ||
| | `ManagedBookmarks` | `array` | Pre-configured bookmarks. Supports folders via nested `children` arrays | | ||
| | `DownloadBubbleEnabled` | `boolean` | Controls the download bubble UI. Set to `false` to fall back to the classic download shelf | | ||

Relative
/api-reference/links will break CI checksHigh Severity
All
/api-reference/...links in the newbrowsers/chrome-policy.mdxpage (lines 10–11) and the updatedbrowsers/pools/policy-json.mdx(line 6) use relative paths. API reference pages are auto-generated from a remote OpenAPI spec and don't exist locally, so relative links will fail themint broken-linksCI check. These need to be absolute URLs (e.g.https://kernel.sh/docs/api-reference/...). Notably,policy-json.mdxpreviously had the correct absolute URL and this PR regressed it to a relative one.Additional Locations (1)
