Steel alternative

The Steel alternative that self-hosts without losing stealth

Steel's open-source server leaves CAPTCHA solving, managed proxies, and its advanced stealth to Steel Cloud. Browserless runs stealth and CAPTCHA solving inside your own network with the licensed image, and includes stealth, proxies, and CAPTCHA solving on the free cloud plan.

Browserless

Browser infrastructure you can run in our cloud or inside your own network. The licensed Enterprise image adds stealth, CAPTCHA solving, and BrowserQL to your own deployment, while the free cloud plan includes stealth routes, residential proxies, and CAPTCHA solving.

Steel

An open-source browser API for AI agents, with a live session viewer, agent traces, and a Credentials API. The open-source server is Apache 2.0 with limited stealth. Steel Cloud adds managed proxies, CAPTCHA solving, and advanced stealth, and Steel Outpost covers self-hosting on Enterprise.

Browserless vs. Steel: how they compare

Both give you a cloud browser over CDP and can run on your own hardware. The differences are in what the open-source and licensed builds include, and what you can test on the free plan.

What is not included on Steel's open-source server?

Neither free build includes CAPTCHA solving or managed proxies. Steel's open-source server keeps limited stealth, while Browserless's open-source image has none, so what do the licensed builds add back?

Steel Browser – Apache 2.0

You get the browser and the session API. Steel's own FAQ says Steel Cloud is what adds scale, stealth, proxies, and CAPTCHA solving, so self-hosting the open-source server means one concurrent session, limited stealth, and bringing your own proxies and solver. Steel's commercial self-host option, Steel Outpost, is sales-led.

Browserless – SSPL-1.0 or commercial

The open-source image covers Puppeteer, Playwright, and the core REST APIs. The licensed Enterprise image adds stealth, CAPTCHA solving, BrowserQL, and session recording, so the build running in your network includes the anti-bot layer. Bring your own proxies.

If the licence is a hard requirement, Steel is the better fit. If you need stealth inside your own network, Browserless ships it.

Moving from Steel to Browserless

Steel creates a session, you connect to it, then you release it. Browserless connects and closes.

  1. 01

    Sign up for free

    Create a free account with no credit card. The free plan includes 1,000 units a month, with stealth, proxies, and CAPTCHA solving already on.

  2. 02

    Drop the create and release calls

    Steel's SDK creates a session and returns a websocketUrl, and you release it when you're done. Browserless connects to one URL, and closing the browser ends the session.

  3. 03

    Move the session flags into the URL

    Steel's useProxy and solveCaptcha become a route and query parameters: /stealth, proxy=residential, and solveCaptchas=true.

  4. 04

    Keep your cleanup, lose the API call

    Your finally block still closes the browser, but there's no session to release afterwards, so there's no second API call to forget. The session ends when the browser closes or the connection drops.

The same job in Steel and Browserless, compared

Both snippets open a session through a residential proxy with CAPTCHA solving on, load a page, and print its title. On Browserless, the /stealth route adds fingerprint protection to the same connection.

BeforeSteel (flags on the session, released at the end)

import puppeteer from "puppeteer-core";
import Steel from "steel-sdk";

const client = new Steel({ steelAPIKey: process.env.STEEL_API_KEY });

const session = await client.sessions.create({
  useProxy: true,
  solveCaptcha: true,
});

try {
  const browser = await puppeteer.connect({
    browserWSEndpoint: `wss://connect.steel.dev?apiKey=${process.env.STEEL_API_KEY}&sessionId=${session.id}`,
  });
  const page = await browser.newPage();
  await page.goto("https://example.com");
  console.log(await page.title());
  await browser.close();
} finally {
  await client.sessions.release(session.id);
}

AfterBrowserless (flags in the connection URL)

import puppeteer from "puppeteer-core";

const TOKEN = process.env.BROWSERLESS_TOKEN;
const browser = await puppeteer.connect({
  browserWSEndpoint:
    `wss://production-sfo.browserless.io/stealth` +
    `?token=${TOKEN}&solveCaptchas=true&proxy=residential`,
});

try {
  const page = await browser.newPage();
  await page.goto("https://example.com");
  console.log(await page.title());
} finally {
  await browser.close();
}

Steel

Best for teams that want an Apache 2.0 core they can fork, Selenium support, and agent traces in one product.

Browserless

Best for teams that want the anti-bot layer maintained for them, in the cloud or on their own hardware, with the same Puppeteer and Playwright connection code either way.
