One endpoint.
You get a WebSocket.
Broswers & Sandboxes.

Connect with Playwright, Puppeteer, Selenium, or raw CDP.
No SDKs. No wrappers.

Playwright

> target: wss://api.chaser.run

> mode: stealth_v2

const browser = await playwright.chromium

.connectOverCDP(cdpUrl)

Puppeteer

> target: wss://api.chaser.run

> mode: stealth_v2

const browser = await puppeteer

.connect({ browserWSEndpoint: cdpUrl })

Selenium

> target: wss://api.chaser.run

> mode: stealth_v2

const options = new chrome.Options()

options.debuggerAddress = cdpUrl

const driver = new Builder()

.forBrowser('chrome')

.setChromeOptions(options)

.build()

Raw CDP

> target: wss://api.chaser.run

> mode: stealth_v2

const ws = new WebSocket(cdpUrl)

ws.send(JSON.stringify({

THE FOUNDATION

REAL BROWSERS
NOT EMULATION

Each session runs in its own isolated microVM.
Real Chromium, real OS, real networking.
No "headless magic". No patched runtimes.

Agents don’t need tricks.
They need infrastructure.

Determinism. Transparency. Control.

Protocols stay intact. CDP stays CDP. Exec stays exec.

BROWSERS

REAL
CHROME

Stealth is what you need when you’re faking it.
Chaser runs real Chrome, in a real VM, on real hardware.

No patched fingerprints. No emulation layers.
Just a browser behaving exactly as it should.

PERSISTENT
EXECUTION

A full Linux environment that pauses when you do.
Resume in milliseconds. State intact.
