The code runs in the same VM as the browser, minimizing latency and maximizing throughput. It has access to 'page', 'context', and 'browser' variables. It can `return` a value, and this value is returned in the response. ## OpenAPI ````yaml https://app.stainless.com/api/spec/documented/kernel/openapi.documented.yml post /browsers/{id}/playwright/execute openapi: 3.1.0 info: title: Kernel API description: Developer tools and cloud infrastructure for AI agents to use web browsers version: 0.1.0 servers: - url: https://api.onkernel.com description: API Server security: - bearerAuth: [] tags: - name: Browsers description: Create and manage browser sessions. - name: Browser Replays description: Record and manage browser session video replays. - name: Profiles description: Create, list, retrieve, and delete browser profiles. - name: Browser Filesystem description: Read, write, and manage files on the browser instance. - name: Browser Computer Controls description: Control mouse, keyboard, and screen on the browser instance. - name: Browser Playwright description: Execute Playwright code against the browser instance. - name: Browser Processes description: Execute and manage processes on the browser instance. - name: Browser Logs description: Stream logs from the browser instance. - name: Extensions description: Create, list, retrieve, and delete browser extensions. - name: Proxies description: Create and manage proxy configurations for routing browser traffic. - name: Browser Pools description: Create and manage browser pools for acquiring and releasing browsers. - name: Managed Auth description: >- Create and manage auth connections for automated credential capture and login. - name: Credentials description: Create and manage credentials for authentication. - name: Credential Providers description: Configure external credential providers like 1Password. - name: Apps description: List applications and versions. - name: Deployments description: Create and manage app deployments and stream deployment events. - name: Invocations description: Invoke actions and stream or query invocation status and events. - name: Projects description: Create and manage projects for resource isolation within an organization. paths: /browsers/{id}/playwright/execute: post: tags: - Browser Playwright summary: Execute Playwright/TypeScript code against the browser description: > Execute arbitrary Playwright code in a fresh execution context against the browser.
