Steel.dev

How it attaches

Browser instrumentation.

Steel.dev is a cloud browser: it hands back a Chrome DevTools Protocol endpoint per session. Trustvice attaches over CDP and records navigation, clicks and DOM events — no extension, no image swap.

Install the Trustvice Chrome extension (desktop) or use the Trustvice-instrumented Chromium image (headless).

1. 1

   Take the session's CDP URL

   When you create a Steel.dev session, keep the session's websocket URL from the Steel sessions API (CDP). It is the same endpoint you would hand to Playwright's connectOverCDP.

2. 2

   Hand it to the Trustvice recorder

   Pass the CDP URL and your workspace API key to the Trustvice browser recorder; it attaches as a second CDP client, so your own automation keeps its connection.

3. 3

   Verify

   Drive one page. Records appear in Witness within a few seconds, tagged with the session id so a run maps to its evidence.

import { recordCdpSession } from "@trustvice/adapter-framework";

// the session's websocket URL from the Steel sessions API (CDP)
const cdpUrl = session.connectUrl;

await recordCdpSession(cdpUrl, {
  workspaceKey: process.env.TRUSTVICE_KEY,
  sessionId: session.id,
});
