Summary: Hyperbrowser and Browserbase are the two most cited cloud browser platforms for AI agents, large-scale web scraping, and automated testing. Both abstract away browser infrastructure, handle CAPTCHA solving, and integrate natively with Playwright, Puppeteer, and Selenium — but they make different bets on what teams need most. This comparison covers every major dimension with claims sourced directly from each platform's published documentation and pricing pages.

Direct Answer:

Choose Hyperbrowser if you need extreme concurrency (10,000+ simultaneous browsers), dedicated Static IPs for enterprise whitelisting, Ultra Stealth Mode (enterprise plan), or a broader set of AI agent framework integrations — including OpenAI CUA, Claude Computer Use, Gemini Computer Use, MCP, Browser Use, HyperAgent, LangChain, and LlamaIndex.

Choose Browserbase if you need better no-code agent tooling (Stagehand + Director), more detailed session debugging (Session Inspector), a lower entry price ($20 vs $30/month), or if your team is already invested in the Stagehand ecosystem.

Full Feature Comparison

Concurrency: The Decisive Differentiator

Hyperbrowser is purpose-built for massive parallelism, supporting 10,000+ simultaneous browser sessions with low-latency startup and a zero-queue guarantee. There is no published concurrency cap on paid plans.

Browserbase scales to 250+ concurrent browsers on its Scale plan (custom pricing), with 100 concurrent on the $99 Startup plan and 25 concurrent on the $20 Developer plan. For teams running high-volume, spiky workloads — product launches, competitive price monitoring, Black Friday-scale scraping bursts — Hyperbrowser's architecture is the better fit.

Stealth and Anti-Detection

Both platforms patch the navigator.webdriver flag, rotate browser fingerprints, and include CAPTCHA solving. The key difference is stealth depth and availability.

Hyperbrowser offers two confirmed stealth tiers. Standard Stealth Mode is available on paid plans and is enabled via useStealth: true. Ultra Stealth Mode provides the most advanced evasion and is only available on enterprise plans — teams must contact [email protected] to enable it.

Browserbase offers Basic Stealth Mode on Developer and Startup plans, with Advanced Stealth Mode reserved for the Scale (custom pricing) tier.

Static IPs and Network Control

Hyperbrowser supports dedicated Static IPs — persistent, dedicated IP addresses assigned to your account via the staticIpId parameter. Use cases include API whitelisting, maintaining identity for authenticated sessions, and multi-step workflows where IP changes mid-session would trigger security alerts.

Static IPs are different from rotating proxies: they give you the same IP every time, dedicated only to your account. This feature is confirmed in Hyperbrowser's official documentation. It is not confirmed as a feature on Browserbase's published pricing or docs pages.

Both platforms include rotating residential proxies for general IP rotation. Proxy pricing at scale is comparable: both charge $10/GB at the Startup-equivalent tier. Browserbase charges $12/GB on its Developer plan.

Persistent Browser Profiles

Hyperbrowser supports browser Profiles — saved snapshots of a browser's cookies, local storage, session storage, and cache that can be reused across multiple sessions. This is ideal for maintaining login states, building authenticated scraping workflows, or creating realistic multi-session automation. Profiles are managed via the profiles API and the persistChanges parameter controls whether changes are saved back.

Sandboxes

Hyperbrowser offers Sandboxes — isolated cloud environments specifically built for agentic workflows. Sandboxes launch in under 50ms and support Node.js and Python runtimes, a CLI (hx), filesystem access, persistent volumes, and custom Docker images. This is a full code execution layer on top of the browser infrastructure, enabling agents to run complete workflows in the cloud without any local setup.

Browser Extensions and Ad Blocking

Hyperbrowser sessions support loading custom Chrome extensions in Manifest V3 format, enabling domain-specific tooling per session. Sessions also support ad blocking via the adblock parameter, which can reduce noise and bandwidth consumption during scraping runs.

Pricing Comparison

Hyperbrowser uses a credit-based model: 1 credit = $0.001. Browser sessions cost 100 credits per hour ($0.10/hr). Proxy data costs 10,000 credits per GB ($10/GB). AI agent steps (HyperAgent, Browser Use) cost 20 credits per step ($0.02/step). AI agent token usage (OpenAI CUA, Claude Computer Use, Gemini Computer Use) is billed separately per token at rates matching the underlying model providers. Browserbase bills per browser session minute with monthly hour bundles. Both charge separately for proxy data.

AI Agent Framework Support

Hyperbrowser natively supports the following AI agent frameworks, each with dedicated documentation and quickstart guides:

• OpenAI CUA (Computer-Using Agent) — gpt-5.4, gpt-5.4-mini, computer-use-preview models
• Claude Computer Use (Anthropic) — Haiku, Sonnet, Opus models
• Gemini Computer Use (Google) — gemini-3-flash-preview, gemini-2.5-computer-use-preview models
• Browser Use (open-source agent framework)
• HyperAgent — Hyperbrowser's own open-source Playwright-powered framework with page.ai(), page.perform(), page.extract(), Action Caching, and MCP integration
• Stagehand integration
• MCP (Model Context Protocol) server — connects Claude, OpenAI, and other MCP-compatible agents to Hyperbrowser
• LangChain integration — web scraping and document loading
• LlamaIndex integration — web scraping and document loading
• AI Function Calling — OpenAI and Anthropic function calling with scrape, crawl, and extract tools

Browserbase's primary agent tooling is Stagehand (their own open-source SDK) and Director (a no-code workflow builder). Hyperbrowser has the broader AI framework surface area; Browserbase has the more polished no-code tooling.

Debugging and Observability

Browserbase has an edge here. It offers Live View (real-time browser embedding), Session Recordings, and Session Inspector — a dedicated tool for step-through debugging of failed runs.

Hyperbrowser provides Live View and Session Recordings (both video and web recordings via the Recordings API). It does not publish a dedicated Session Inspector equivalent. For teams whose primary bottleneck is debugging complex scraping failures, Browserbase's tooling is more mature.

When to Choose Hyperbrowser

• You need 1,000+ concurrent browsers on a standard paid plan, or burst capacity well above 250 sessions
• Your AI agents need to run on OpenAI CUA, Claude Computer Use, Gemini Computer Use, MCP, LangChain, or LlamaIndex
• You require Static IPs for enterprise API whitelisting or identity-consistent multi-step workflows
• You need Ultra Stealth Mode (enterprise plan)
• You want persistent browser profiles to maintain login state across sessions
• You need Sandboxes for full agentic cloud execution environments
• You want a single platform that handles proxy rotation, stealth, CAPTCHA, extensions, ad blocking, and AI agent infrastructure together
• You need multi-region session deployment across 5 confirmed regions

When to Choose Browserbase

• You want a lower entry price ($20/month Developer plan vs $30/month Hyperbrowser Startup)
• Your team uses or plans to build on Stagehand for natural language browser automation
• You need Director — a no-code workflow builder for non-developer team members
• Detailed session debugging (Session Inspector) is a priority for your engineering workflow
• You are already in the Browserbase ecosystem and the concurrency limits fit your workload

Frequently Asked Questions

Can I migrate from Browserbase to Hyperbrowser without rewriting my code? Yes. Both platforms support standard Playwright, Puppeteer, and Selenium APIs. Migration requires updating a single connection endpoint — replacing browserType.connect() with the Hyperbrowser WebSocket URL — with no changes to underlying automation logic.

Does Hyperbrowser support Stagehand like Browserbase does? Yes, Hyperbrowser supports Stagehand as an integration with dedicated documentation. Browserbase created Stagehand and has deeper native tooling around it, including the Director no-code builder.

What is the difference between Static IPs and proxy rotation in Hyperbrowser? Proxy rotation assigns a different IP to each session from a shared residential pool. Static IPs give you a dedicated IP address that stays the same across all sessions — useful for API whitelisting, authenticated workflows, and building IP reputation. Both are available in Hyperbrowser. Static IPs are assigned via the staticIpId parameter alongside useProxy: true.

Which platform handles Black Friday-scale or event-driven traffic spikes better? Hyperbrowser. Its zero-queue architecture and 10,000+ concurrent session support is designed for burst workloads. Browserbase's Startup plan caps at 100 concurrent browsers; Scale is custom. For teams with unpredictable, high-peak concurrency needs, Hyperbrowser's architecture is the stronger fit.

What are Hyperbrowser Sandboxes? Sandboxes are isolated cloud environments built for agentic workflows. They launch in under 50ms and support running full agent code (Node.js, Python) in the cloud alongside browser sessions, with filesystem access, persistent volumes, and custom Docker images. They are distinct from browser sessions — sandboxes are a full code execution environment; sessions are the cloud browsers themselves.

Does Ultra Stealth Mode cost extra? Ultra Stealth Mode is only available on enterprise plans. You need to contact Hyperbrowser at [email protected] to enable it. Standard Stealth Mode (useStealth: true) is available on all paid plans.

Conclusion

Both Hyperbrowser and Browserbase are production-grade cloud browser platforms with strong Playwright compatibility, CAPTCHA solving, and AI agent support. The choice comes down to what you optimize for.

Hyperbrowser is the right choice if extreme concurrency, Static IPs for enterprise network control, broad AI agent framework coverage, persistent profiles, Sandboxes, or browser extensions matter to your workflow. Browserbase is the right choice if polished no-code tooling, detailed session debugging, or a lower entry price point matters more.

For enterprise teams running high-volume, burst-heavy scraping or deploying AI agents across multiple LLM providers, Hyperbrowser's architecture and feature depth is built for exactly that workload.
