BROWSER
Real Chrome, over CDP
Drive it with Playwright, Puppeteer or raw DevTools. Watch it live, or take over when a person needs to step in.

Private beta is open
Give your AI agents the infrastructure they need.
Browsers, shells, storage and isolated machines, through one API. One call starts Chrome, bash and a shared disk on its own machine, billed by the second.

Layers
One session. Every layer an agent needs.
Real agent tasks cross the line between browsing and computing. Pick a job and see which layers of the session it uses.
Every session gets
Four surfaces. One machine.
SHELL
A shell with sudo
Bash on the same machine as the browser, with Python, Node and ffmpeg ready. Run the code your agent just wrote.
bashpythonnodeffmpeg
/WORKSPACE
One shared disk
Downloads from the browser land where the shell can read them. Pull results out through the files API.

MACHINE
Isolated, never shared
Every session runs on its own machine under gVisor. Its browser, shell and disk belong to one customer only.

Quickstart
Four calls, start to finish.
agent.ts
import { chromium } from "playwright-core";import { Boxline } from "@boxline/sdk"; const bx = new Boxline(); // reads BOXLINE_API_KEY // One call: Chrome, bash and /workspace on one machineconst session = await bx.sessions.create({ shell: true }); const browser = await chromium.connectOverCDP(session.connectUrl!);const page = browser.contexts()[0].pages()[0];await page.goto("https://portal.acme.com/reports");await page.click("text=Download CSV"); // The download is already on the shared diskawait session.files.waitFor("downloads/*.csv");await session.exec("python3 summarise.py downloads/report.csv"); await session.stop(); // billing stops here; resume it later, or delete itWeb data
Fetch, crawl and search the web.
Any page, as clean data
Get a page as Markdown, HTML or text in one call. Screenshots and PDFs have calls of their own.
A whole site, page by page
Start from one address and follow links across a site, with a webhook when the crawl finishes.
Search, then read the results
Get web results for a query, and the top pages as Markdown in the same call.
Security
A sandbox of its own, for every session.
Agents open untrusted pages and run code they wrote a moment ago. Each session stays contained, and nothing is shared between customers.
How we handle isolation and data- LIVE
gVisor per session
Processes in a session never talk to the host kernel directly.
- LIVE
Never shared
A session's browser, shell and disk belong to one customer only.
- LIVE
Stop frees the machine
Stopping a session frees its machine and stops billing at that second. Delete removes what it saved.

MicroVM isolation
Coming next. We'll announce it in the changelog.

FAQ
Questions, answered.
By the second, from the moment a session starts until you stop it. There is no per-session fee, and a stopped session costs nothing.
Stopping saves the whole browser (every tab, cookies and storage) and the files in /workspace, frees the machine and stops billing at that second. A stopped session is free and is kept for your plan's retention, 7 to 90 days. Resume it any time with the same id, as it was, or delete it.
Yes. Every session exposes a Chrome DevTools Protocol endpoint, so Playwright, Puppeteer and other CDP clients connect with one line.
Chrome, bash, Python, Node and ffmpeg, with sudo. Browser downloads and shell output share the same /workspace disk.
Each session runs in its own gVisor sandbox and is never shared between customers. MicroVM isolation is on the roadmap.
A $5 usage credit every month and up to 3 concurrent sessions of up to 15 minutes, with the browser, shell and /workspace included.
Start
Start a session in one call.
The free plan comes with $5 of usage credit every month. Sessions are billed by the second and stop billing the moment you stop them.
