Steel
Open-source browser infrastructure for AI agents that provides managed Chrome instances with session persistence, proxies, and anti-bot handling. Exposes a REST API and Playwright/Puppeteer-compatible SDK so agents can browse, click, and extract data without managing browser infrastructure. Self-hostable or available as a cloud service.
Solid choice for most workflows
You're building an AI agent that needs to interact with websites at scale, but managing browser infrastructure, proxies, CAPTCHA solving, and session state is consuming engineering time that should go to agent logic.
Sub-1-second session startup in same region (vs 3-5s for self-managed). Token efficiency gains up to 80% through intelligent content extraction. Built-in stealth and proxy handling eliminate most bot-detection friction. Trade-off: you're dependent on Steel's uptime and pricing model for production scale.
Your agent needs to maintain authenticated sessions across multiple steps (login → navigate → fill forms → extract data), but session state keeps getting lost or authentication breaks between requests.
Reliable state persistence across requests. Each session gets dedicated resources (2GB RAM, 2GB vCPU). Scaling is automatic on the cloud tier; self-hosted requires manual orchestration.
You need to run multiple browser instances in parallel for real-time scraping or concurrent agent tasks, but Kubernetes is overkill and serverless (Lambda/Cloud Run) introduces cold-start latency that breaks long-running workflows.
Effortless horizontal scaling without cold starts. Cloud tier handles infrastructure automatically. Self-hosted requires you to manage scaling logic and resource allocation. Pricing is per-browser-hour; high-concurrency workloads can get expensive fast.
Steel is a managed wrapper around browser automation; Puppeteer/Playwright are the underlying libraries. Steel saves infrastructure work; raw Puppeteer/Playwright give you full control.
You want to ship fast and don't want to manage proxies, CAPTCHA solving, bot detection, or browser scaling. Cloud-first teams.
You need absolute control over browser behavior, have existing Puppeteer/Playwright code, or want zero cloud dependencies. On-premise or cost-sensitive deployments.
Pricing scales with concurrency and session duration
Steel charges per browser-hour. A single 24-hour session costs the same as 24 one-hour sessions. High-concurrency agents (100+ parallel sessions) can consume credits rapidly. Monitor usage in the Steel dashboard; set alerts or implement session pooling to avoid surprise bills.
