Switching from Browserbase # Move your agent's browsers from the cloud to your PC. Playwright connects to a profile on your own PC instead of a cloud session, so only the lines that start the browser change. Each profile keeps its own identity, cookies and logins between runs.

Your agent's code keeps working as it is. Where its browsers run, their proxies and their logins are set up new in four steps. ### Stays the same * Your agent's code Every call after the start runs as before: the same pages, clicks and reads, in the same Playwright calls. * Playwright, Puppeteer, Selenium A profile's start hands back cdp_ws for connect_over_cdp and puppeteer.connect, and debug_port for chromedriver. * Headless runs Your runs can stay in the background. Each start picks headless or a window you can watch and work in. ### Starts fresh * Where the browsers run On your Windows PC with a real graphics card, instead of a cloud. macOS and Linux are coming soon. [1Install Scalebrowser on your PC](https://scalebrowser.net/switch/browserbase#move-install) * The session lines There is no Browserbase-compatible API. The lines that create a session become a start of the profile. [2Connect your agent](https://scalebrowser.net/switch/browserbase#move-connect) * Your proxies You bring your own. Scalebrowser checks each one and sets the profile's time zone and language to its country. [3Create profiles from a preset](https://scalebrowser.net/switch/browserbase#move-profiles) * Your logins They start fresh in each new profile: sign in once per site, or let your agent store the login in the vault without seeing it. [4Sign in once per site](https://scalebrowser.net/switch/browserbase#move-logins) ### What you gain * An identity from your PC Each profile runs on your own PC: graphics card and screen come from its real hardware, time zone and language from its proxy. * Logins the agent never sees Each profile keeps its cookies and logins, and your agent signs in from its vault without ever seeing the password. * Workflows Turn a repeat job into a workflow of 89 blocks, run it over many profiles and start it on a schedule, by webhook or from your agent. * Run videos A run becomes a video with zoom on the clicks and a cursor that follows, shared by link. * Pay by browsers at once Plans count the browsers running at the same time: Solo runs 5 at once with 100 profiles for $49 a month. ## The move, in four steps. From the install to the last login, with your agent's code as it is. 1. ### Step 1: Install Scalebrowser on your PC The Windows app runs the profiles and serves the REST API, MCP and CDP on 127.0.0.1:8787, behind a token. 2. ### Step 2: Connect your agent Hand a profile's cdp_ws to Playwright's connect_over_cdp, or add Scalebrowser to Claude Code, Cursor or ChatGPT over MCP. 3. ### Step 3: Create profiles from a preset Your proxies are checked first. Then each new profile gets its own identity in its proxy's country. 4. ### Step 4: Sign in once per site Each new profile starts signed out. Sign in once and it stays signed in, or let your agent store the login in the profile's vault without seeing the password. ## Before you switch, short answers. A line or two each. Every call and field is in the [CDP docs](https://scalebrowser.net/docs/cdp). ### No, the start lines change. Start a profile with ScalebrowserClient and hand started.cdp_ws to Playwright's connect_over_cdp. Everything your agent does after that line stays as it is. See the [CDP docs](https://scalebrowser.net/docs/cdp). ### ### ### ### ### ## Your agent stays as it is. Its browsers move to your PC. Install Scalebrowser, start a profile, and connect Playwright to it or your agent over MCP.
