The verdict
Steel appears in 3 AI-ranked categories — best position #2 for hosted browser infrastructure for agents using authenticated websites.
Open-source browser infrastructure paired with a managed cloud service, providing persistent session profiles, built-in proxy rotation, and full deployment flexibility without vendor lock-in; near-tie with Browserbase for teams prioritizing self-hosting capabilities. (Assumes open control and data sovereignty are critical).
Grok Profiles persist full browser identity (cookies, auth tokens, fingerprints, extensions, localStorage) so authenticated agents resume exactly where they left off; Credentials API injects secrets/TOTP without exposing them to the LLM or logs; open-source + self-hostable with strong stealth/CAPTCHA/proxy primitives; fastest measured session lifecycle among peers for production authenticated runs. Near-tie with Browserbase on pure auth durability.
Claude Open-source browser-API with a hosted option, giving self-host control over where cookies and session data live — a real advantage when credentials are sensitive or compliance forbids third-party auth storage. Clean session API, proxy and CAPTCHA support, and no vendor lock-in. Best value for engineering teams willing to run infra.
GPT Strong value and portability: fast CDP browsers, persistent profiles, secure credential injection, automatic TOTP, proxies, CAPTCHA solving, dedicated IPs, and an Apache-licensed self-hostable core.
Where Steel falls short, per the models
- GPT Profiles are limited to 300 MB and automatically deleted after 30 inactive days, a poor fit for large or infrequently used account fleets.
- Claude Self-hosting the stealth/proxy/anti-bot stack is on you; the managed tier is less feature-deep than Browserbase, so heavy anti-bot targets take more work.
- Gemini Requires more manual orchestration for complex anti-bot challenges and lacks turnkey higher-level agent frameworks out of the box.
- Grok Less opinionated agent SDK/orchestration layer (you wire Playwright or browser-use yourself); smaller ecosystem and adoption than the managed leaders.

Top alternatives per the models: Browserbase · Kernel · Anchor Browser · Browser Use Cloud
The strongest open-source-first choice — Steel Browser can be self-hosted for full data control, with a managed cloud offering the same API; purpose-built for agents (session recording, proxies, anti-detect, auth/cookie persistence) and a clean REST/SDK that mirrors Browserbase's ergonomics.
Gemini Open-source-first managed browser infrastructure designed explicitly for AI agents, providing session management, anti-detect browser instances, proxy rotation, and CDP compatibility while eliminating vendor lock-in via self-hosting capabilities; assumes self-hostability is vital for privacy and cost control. Near-tied with Browserbase on agent feature design.
Grok Open-source core plus managed cloud delivering industry-leading sub-second session lifecycle, persistent profiles for auth/state, built-in stealth/CAPTCHA/proxies, live viewer + MP4 traces, and 1-line Playwright/Puppeteer compatibility; strong real value from self-host escape hatch and transparent performance data for agent fleets
Where Steel falls short, per the models
- Claude The managed cloud is smaller and less proven at extreme scale than Browserbase, and self-hosting shifts stealth/proxy/ops burden onto you — not for teams that want a hands-off, guaranteed-scale SLA.
- Gemini Managed cloud infrastructure platform has a shorter operational track record and a smaller ecosystem of turnkey agent integrations than older legacy platforms.
- Grok Less opinionated agent layer than Stagehand-style tools, so teams must wire their own higher-level orchestration and accept Chrome-only focus

Best open-source browser-infrastructure choice for AI applications, combining self-hostability with managed sessions, CDP/Playwright/Puppeteer/Selenium access, persistent state, proxies, and agent-framework integrations
Claude Open-source, self-hostable browser API built for agents—session management, proxies, stealth, and a clean REST/SDK surface, with a hosted option too. Best for teams that want Browserbase-style ergonomics without vendor lock-in and with full control over where browsers run.
Gemini Offers an open-source, self-hostable and cloud-ready browser infrastructure with built-in stealth, session persistence, and drop-in compatibility for existing Playwright and Puppeteer agents.
Grok Open-source browser API with best-in-class measured session lifecycle (~0.9 s), persistent profiles, stealth, CAPTCHA/proxy support and live/replay observability, designed for agent fleets with self-host or managed path.
Where Steel falls short, per the models
- GPT A smaller and less battle-tested managed ecosystem than the top three makes it a higher-ownership choice for demanding production workloads
- Claude Smaller ecosystem and less polish/scale-proofing than Browserbase; self-hosting the fleet still puts operational burden on you.
- Gemini Smaller community ecosystem and fewer out-of-the-box high-level agentic reasoning abstractions compared to dedicated agent frameworks.
- Grok Infra-only (bring your own agent loop); fewer high-level AI primitives than Browser Use or Stagehand.
