Browserless vs Browserbase vs Steel.dev: Cloud Browser Showdown 2026

—

Cloud browser APIs have quietly become the backbone of serious scraping infrastructure in 2026. if you’re choosing between Browserless, Browserbase, and Steel.dev for a production pipeline, the decision isn’t just about price per session — it’s about fingerprint resistance, concurrency scaling, and how much control you’re willing to give up. this comparison cuts through the marketing and gives you what actually matters.

What Each Platform Is Actually Doing

Browserless (v2, now at browserless.io) runs headless Chrome over a WebSocket API. you connect via Playwright or Puppeteer using a browserWSEndpoint, and Browserless manages the browser pool. it’s the oldest of the three and has the largest self-hosted install base. the v2 rewrite added stealth mode and session persistence, but fingerprint evasion is still shallow compared to dedicated anti-detect tooling.

Browserbase positions itself as the “reliable browser infrastructure for AI agents.” it runs Chromium with built-in proxy rotation, session recording, and a live debug viewer. the key differentiator is its Session API — you can resume a named session across requests, which matters for multi-step login flows and stateful scraping. it integrates natively with LangChain, CrewAI, and the Stagehand SDK. if you’re building agentic pipelines, this is the platform designed for that use case; see the broader context in Agentic Browsers Explained: Browserbase, Browser Use, and Proxy Infrastructure.

Steel.dev is the newest entrant (public launch late 2025). it’s open-source at its core, self-hostable, and built around an API surface that mirrors Browserbase’s Session API closely. the pitch: Browserbase-style ergonomics without the vendor lock-in. Steel also ships with a /scrape endpoint that returns cleaned Markdown, which is useful for LLM pipelines that just need page content without writing Playwright code.

Side-by-Side Comparison

Feature	Browserless v2	Browserbase	Steel.dev
Protocol	CDP / WebSocket	CDP + REST Sessions API	CDP + REST Sessions API
Self-hosted	yes (Docker)	no	yes (Docker)
Stealth / fingerprint	basic (v2 stealth mode)	moderate (built-in proxy rotation)	moderate (inherits Chromium defaults)
Session persistence	manual (cookies only)	yes (named sessions)	yes (named sessions)
Live debug viewer	no	yes	yes
AI agent SDKs	Playwright/Puppeteer	Stagehand, LangChain, CrewAI	Stagehand compatible
Pricing model	per-minute + concurrency	per-session + minutes	per-minute (cloud) / free self-hosted
Open source	partial	no	yes (MIT)

Fingerprint and Proxy Considerations

None of these three platforms are purpose-built anti-detect browsers. for fingerprint-level evasion — canvas noise, WebGL spoof, font enumeration control — you still need a layer like Patchright or a dedicated anti-detect browser. the article Patchright vs Rebrowser-Patches: Stealth Playwright Patches Compared 2026 covers exactly how to bolt stealth patches onto a Playwright connection, which applies cleanly to any of these three backends.

for residential proxy pairing, Browserbase has the smoothest integration: you pass a proxy config at session creation and it handles rotation per-request. Browserless requires you to launch Chrome with --proxy-server at the worker level, which means all sessions on a worker share the same proxy exit. Steel.dev matches Browserbase here — proxy config is per-session via the API body.

if you’re running multi-account workflows with anti-detect profiles, the browser choice interacts heavily with your proxy pairing strategy. the Aqum Browser Proxy Setup 2026: Anti-Detect + Residential Pairing guide is worth reading before you commit to a cloud browser API for that use case, because cloud browsers and dedicated anti-detect profiles solve overlapping but distinct problems.

Connecting via Playwright (Code Example)

Browserbase and Steel.dev both expose a WebSocket endpoint you connect to with browserType.connectOverCDP(). here’s a minimal session creation + connect flow for Browserbase:

import httpx
from playwright.sync_api import sync_playwright

API_KEY = "bb_live_xxxxxxxxxxxx"

# create a named session
session = httpx.post(
    "https://www.browserbase.com/v1/sessions",
    headers={"x-bb-api-key": API_KEY},
    json={"projectId": "your-project-id", "proxies": True},
).json()

ws_url = session["connectUrl"]

with sync_playwright() as p:
    browser = p.chromium.connect_over_cdp(ws_url)
    page = browser.new_page()
    page.goto("https://example.com")
    print(page.title())
    browser.close()

Steel.dev’s equivalent is nearly identical — swap the session creation endpoint and auth header. Browserless uses a simpler browserWSEndpoint URL with your API key as a query param, no session pre-creation needed.

When to Use Which

Choosing depends on three variables: control, statefulness, and whether you’re building an agent or a scraper.

Choose Browserless if:

you want self-hosted and already run Docker on your infra
your scraping is stateless (one URL, extract, done)
you need maximum concurrency at minimum cost and will manage proxies yourself

Choose Browserbase if:

you’re building an AI agent that needs to navigate multi-step flows
you want built-in session replay for debugging (the live viewer is genuinely useful)
you need a managed platform with SLA and don’t want to operate infrastructure

Choose Steel.dev if:

you want Browserbase-style ergonomics with the option to self-host
your pipeline needs the /scrape Markdown endpoint for LLM consumption
you want open-source auditability

for keyboard-driven or lightweight automation that doesn’t need a full cloud browser, it’s worth knowing that tools like those covered in Surfing Keys, Vimium, Tridactyl: Keyboard Browser Automation for Scraping can handle simpler extraction tasks at zero infrastructure cost.

for teams running Facebook or social ad account workflows, cloud browsers alone won’t protect you. browser fingerprint isolation requires dedicated profiles, which is a separate concern from session management — the guide on Best Multi-Account Browser for Facebook Advertising Profiles (2026) lays out why profile isolation matters beyond just proxy assignment.

Pricing Reality in 2026

Browserless cloud: roughly $0.006 per minute of browser time, with a free tier of 6 hours/month. at 10 concurrent sessions running 30 minutes/day, you’re at ~$54/month.

Browserbase: session-based pricing, approximately $0.01 per session-minute on the growth plan. the same workload runs closer to $90/month, but you get the debug viewer and managed proxies included.

Steel.dev cloud: similar per-minute pricing to Browserless, but self-hosted is free. for teams with existing infra, the self-hosted path makes Steel the cheapest option at scale.

Bottom Line

for pure scraping workloads, Browserless self-hosted is still the most cost-efficient option if you can manage the ops overhead. for AI agent pipelines that need stateful sessions and debugging tools, Browserbase is worth the premium. Steel.dev is the right pick if you want the Browserbase API surface without the lock-in, especially since the self-hosted path is production-ready. DRT will keep tracking how these platforms evolve as anti-bot detection tightens through 2026.
