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.
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.
Top alternatives per the models: Browserbase · Browserless · Bright Data Scraping Browser · Hyperbrowser
A near-tie with Browserbase for developers prioritizing open-source, delivering a robust API-compatible browser-as-a-service with stealth features and session recordings that can be fully self-hosted.
GPT 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
Grok Strong open-source headless browser API tailored for AI agents with cloud/self-host options, session management, anti-bot features, good for fleets and production scaling without vendor lock-in.
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
- Gemini Running it self-hosted requires substantial DevOps and infrastructure overhead to manage and rotate proxies to bypass aggressive bot detection.
- Grok Younger/less mature ecosystem than Playwright/Browserbase for some edge cases.
