Steel Browser
Open-source cloud browser API for AI agents, scraping, and RPA
Steel is a solid pick for developers who want cloud browser orchestration without the enterprise price tag. The free tier, open-source model, and built-in CAPTCHA solving give it real value for prototyping, and the new Stealth Browser and Rust/Go SDKs strengthen production appeal. Watch the metered Scale plan — at $0.40/browser hour plus dedicated IP add-ons, heavy usage can get pricey.

Skip Steel if you only need to scrape static HTML pages (a plain HTTP client is simpler) or if you require a no-code browser automation tool.
The free Launch tier caps you at 5 browser hours per month and 2 concurrent sessions — you'll hit the limit fast if you prototype more than a few sessions.
Steel's free tier (5 browser hours/month) and metered Scale plan ($0.40/hr) undercut Browserbase's entry pricing, and its open-source model gives you self-host flexibility. For heavy production scraping, per-hour rates on both won't match flat-fee plans, but Steel's predictability and control make it a strong fit for dev teams and startups.

About Steel Browser
Steel is an open-source browser API that lets you spin up on-demand cloud browser sessions with a single API call. Built for AI agents, large-scale scraping, RPA, and QA workflows, Steel abstracts away browser infrastructure management so you can focus on automation logic rather than session lifecycle, CAPTCHAs, and bot detection. With sessions launching in under a second, Steel claims to have served over one million browser hours and 800 billion scraped tokens, making it a production-ready option. Steel handles the messy parts of browser automation. It includes built-in CAPTCHA solving, proxy and browser fingerprinting controls to avoid bot flags, and persistent browser profiles that save and inject cookies and local storage. Sessions can run up to 24 hours, and the Session Viewer gives you live and recorded observability for debugging. For auth-walled sites, Steel offers secure auto sign-in. Current development strengthens its production story. Launch Week v3 introduced the Stealth Browser custom Chromium fork, Dedicated IPs for stable network origin, Atlas (an open-source deep research harness), and native Rust and Go SDKs alongside Node.js and Python. Steel integrates with agent frameworks like Browser Use, Stagehand, and OpenAI's Computer Use, and switching from local Puppeteer to Steel is often a one-line change. Pricing is simplified into three plans—Launch, Scale, and Enterprise—with metered browser-hour rates. The free Launch tier offers 5 browser hours per month, making it easy to prototype. For teams that need predictable cloud browser costs without a heavy enterprise contract, Steel balances control, cost predictability, and open-source flexibility. Compared to Browserbase, Steel's open-source model and lower entry cost are a draw for developers.
Behind the Verdict
Steel is a developer-focused browser automation platform that shines when you need to run fleets of browsers in the cloud without building your own infrastructure. Its strengths are clear: instant session startup (under 1 second), built-in CAPTCHA solving, proxy and fingerprinting controls, and persistent profiles that let you maintain state across sessions. The Session Viewer is a standout — live and recorded debugging is critical for diagnosing flaky automations, and Steel makes it first-class. The open-source model is a genuine differentiator. You can self-host or inspect the code, which is rare among cloud browser providers. Launch Week v3 added meaningful production features: Stealth Browser (a custom Chromium fork), Dedicated IPs, Atlas (a deep research harness), and native Rust/Go SDKs. These address real pain points for agent developers stuck with bot detection and unstable network origins. Where Steel falls short: the free tier is tight (5 browser hours/month, 2 concurrent sessions), so you'll likely upgrade quickly if you're doing anything serious. The metered Scale plan can get expensive at high volume — $0.40 per browser hour plus optional add-ons like Dedicated IPs. Also, Stealth Browser is new and may have compatibility quirks with existing Puppeteer/Playwright scripts. For teams that need a fully managed enterprise solution with dedicated support and compliance, Steel's Enterprise tier is custom-priced, which may be overkill for small teams. Best fits: AI agent developers, scraping teams, RPA engineers, and QA folks who need reliable cloud browsers with observability. Not ideal for no-code users or those who need only static HTML scraping — a plain HTTP client would be simpler and cheaper.

Real-world workflow fit
Concrete scenarios for the personas Steel Browser actually fits — and what changes day-one when you adopt it.
You're building an autonomous shopping agent that compares prices and completes purchases. You need a cloud browser that can handle CAPTCHAs and persist login state.
Outcome: With Steel, you spin up a session via API, pass browser context via cookies, and let the agent browse. The Session Viewer gives you live debugging so you can watch the agent's steps and intervene if it gets stuck. Auto CAPTCHA solving keeps the flow moving.
You're scraping a large e-commerce site for training data. You need concurrent sessions, reliable proxies, and the ability to reuse logged-in state across runs.
Outcome: You create multiple sessions concurrently, each with persistent profile injection. Steel's built-in proxy and fingerprinting controls reduce bot detection, and Dedicated IPs (paid add-on) ensure stable origin if needed. You scrape thousands of pages in minutes, with recorded sessions for post-hoc analysis.
You're automating end-to-end tests across multiple browser profiles and extensions. You need to see what went wrong when tests fail.
Outcome: You launch isolated cloud sessions per test, each with its own profile and extensions. When a test fails, you replay the session recording to see exactly what happened. This saves hours of debugging flaky tests.
Use Cases
- Autonomous AI shopping agents that browse e-commerce sites, compare prices, and complete purchases.
- Large-scale web scraping for training datasets using concurrent sessions and persistent profiles.
- RPA workflows that log into portals, fill forms, and extract data with CAPTCHA handling.
- Customer service agents that access auth-walled dashboards to perform actions on behalf of users.
- End-to-end QA testing across multiple browser profiles and extensions in isolated cloud sessions.
- Deep research agents using Atlas to gather evidence and generate cited reports.
- Sales automation, like lead enrichment and outreach workflows.
- Foundational model training by scraping web data at scale.
Models Under the Hood
as of 2026-08-21
Limitations
- The free Launch plan caps concurrent sessions to 2 and includes only 5 browser hours per month.
- Production agent workloads may require Dedicated IPs (paid add-on) to avoid blocked requests, which adds to cost.
- The Stealth Browser fork is new and may have compatibility differences with some Puppeteer or Playwright scripts.
- The metered Scale plan can become expensive at high volume ($0.40 per browser hour, plus add-ons).
- Also, while Steel offers on-premise options for Enterprise, the pricing is custom and may be prohibitive for small teams.

Where the pricing makes sense
The company stage and team size where Steel Browser's pricing actually pencils out — and where peers do it cheaper.
Steel's free tier (5 browser hours/month) and metered Scale plan ($0.40/hr) undercut Browserbase's entry pricing, and its open-source model gives you self-host flexibility. For heavy production scraping, per-hour rates on both won't match flat-fee plans, but Steel's predictability and control make it a strong fit for dev teams and startups.
Setup time & first value
How long it actually takes to get something useful out of Steel Browser — broken out by persona, not the marketing-page minute.
For a Node.js developer, you can get your first session running in under 10 minutes: sign up, install the SDK (npm install @steel-dev/steel-sdk), and call sessions.create(). Converting existing Puppeteer scripts is a one-line change (puppeteer.connect instead of puppeteer.launch). Python, Rust, and Go SDKs are equally quick. The free tier gives you 5 hours to experiment.
Switching to or from Steel Browser
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From Browserbase: Steel's API is similar, so you can often switch by changing the client initialization and base URL. Its open-source nature means you can self-host if needed.
- ↗To Browserbase: Since both offer cloud browser APIs, you can map Steel session methods to Browserbase's API. But you'll lose Steel's open-source flexibility and lower entry pricing.
