Steel Review 2026: Browser Infrastructure for AI Agents and Pricing

Run browser agents with managed sessions, proxies, profiles, credentials, replays, and observability

Checked this monthResearch BasedFreemiumCodeAutomationSecurity
Recently Updated

Who should use this?

Developers deploying browser and computer-use agents and Automations requiring persistent authenticated sessions.

Who should avoid it?

Unauthorized automation or terms violations, Consequential writes without human approval

What problem does it solve?

Steel is an open-source browser API and managed cloud runtime for AI agents, offering sessions, browser tools, proxies, CAPTCHA handling, persistent identity, and credential injection.

Would I recommend it?

Steel earns a pilot for browser-agent teams that need observable, persistent cloud sessions and do not want to manage Chromium infrastructure. Start with read-only tasks, isolate one profile and identity per account, keep spending and domain allowlists tight, and treat credential injection as secret protection—not permission to let an agent act without review.

Direct verdict

Steel earns a pilot for browser-agent teams that need observable, persistent cloud sessions and do not want to manage Chromium infrastructure. Start with read-only tasks, isolate one profile and identity per account, keep spending and domain allowlists tight, and treat credential injection as secret protection—not permission to let an agent act without review.

What to verify

Run 500 approved tasks across public, authenticated, file-download, CAPTCHA, multi-tab, and failure-recovery cases. Use separate least-privilege test accounts and approval-gate every write. Measure completion, wrong-action and duplicate-action rates, credential exposure, tenant isolation, replay usefulness, profile corruption, blocked pages, proxy bandwidth, CAPTCHA solves, browser minutes, cold starts, p95 latency, and total cost per safely completed task. Inject prompt attacks and provider outages before production approval.

  1. Confirm the tool meets every must-have workflow and stakeholder requirement.

    Review starting point: Developers deploying browser and computer-use agents; Automations requiring persistent authenticated sessions; Teams needing replayable managed browsers

  2. Run the same representative work you would use in production; do not score a polished demo.

    Review starting point: Complete three to five representative tasks with known acceptable outcomes and compare them with your current process.

  3. Calculate the effective cost per accepted result, including usage, review, corrections, and required add-ons.

    Review starting point: Steel Launch is $0 plus usage with $30 in one-time credits valid for 90 days, ten concurrent sessions, and 15-minute sessions. Listed Launch rates include $0.10 per browser hour, $10 per GB of proxy bandwidth, $3 per 1,000 CAPTCHA solves, and $5 per 1,000 one-shot browser-tool calls.

  4. Define an acceptance threshold, test known answers and edge cases, and record every correction.

    Review starting point: Editorial quality signals: features 4.3/5; AI quality 4.1/5. Validate these signals in your own work.

  5. Verify what data enters the product, who can access it, how long it is retained, and whether it trains models.

    Review starting point: Use approved low-risk data first. Check roles, consent, deletion, subprocessors, model-training settings, and the contract—not only the marketing page.

  6. Test the real handoffs, permissions, failure states, and export path your team depends on.

    Review starting point: Playwright, Selenium, OpenAI Computer Use, Claude Computer Use, Browser Use, CrewAI

  7. Record training, governance, reliability, accessibility, ownership, and change-management risks before rollout.

    Review starting point: Authenticated browser state creates significant security risk; Multiple meters can produce surprise costs; Entry sessions and retention are deliberately limited

Browser Use

Open-source and cloud infrastructure for AI agents that navigate websites

4.0

Browser Use helps developers run web agents, remote browsers, profiles, proxies, and reusable skills, but reliability, credential custody, website rules, variable usage costs, and human approval are decisive.

E2B

Ephemeral cloud sandboxes for agents that execute code and use virtual computers

4.0

E2B isolates agent-generated code in disposable cloud environments, but network egress, secrets, persistence, images, concurrency, and usage cost still require production controls.
