Why You Need Proxies for Browserbase

Browserbase is a headless browser platform designed for AI agents, web scrapers, and automation workflows. It provides managed Chromium instances that AI agents can control programmatically to browse the web, fill forms, extract data, and interact with web applications.

Without proxies, Browserbase sessions run on cloud infrastructure IPs that are easily identified and blocked by anti-bot systems. Major websites maintain blocklists of known cloud provider IP ranges (AWS, GCP, Azure) and reject connections from these ranges on sight. Even sites without explicit blocklists often treat cloud IPs with lower trust, triggering CAPTCHA challenges and rate limiting.

Hex Proxies solves this by routing Browserbase traffic through residential or ISP IP addresses. The target website sees a connection from a real ISP subscriber rather than a cloud server, bypassing IP reputation-based blocking entirely. This is essential for AI agents that need reliable web access across diverse sites.

The combination of Browserbase managed browsers and Hex Proxies clean IPs creates a robust foundation for AI agent web access. Browserbase handles the browser lifecycle and rendering complexity. Hex Proxies handles the network identity, ensuring every page load and API call appears legitimate.

Best Proxy Type for Browserbase

The optimal proxy type depends on your Browserbase use case:

**Residential proxies** are the best choice for broad web scraping and data collection workflows. They provide the highest IP diversity (10M+ IPs) and strongest anti-bot bypass rates. Per-request rotation means each page load uses a different residential IP. Use residential proxies when your Browserbase agents access many different websites or face aggressive anti-bot protection.

**ISP proxies** are ideal when you need consistent IP identity across a browser session. ISP proxies provide dedicated IPs registered to real Internet Service Providers like Comcast and Windstream, combining residential trust scores with datacenter-grade speed and reliability. Use ISP proxies for authenticated sessions, multi-page workflows, and use cases where session IP consistency matters.

For most Browserbase users running AI agents, residential proxies with sticky sessions offer the best balance -- residential trust for anti-bot bypass with session persistence for multi-step workflows. Set sticky session duration to match your typical browsing flow (5-30 minutes).

How to Use Hex Proxies with Browserbase

Browserbase supports proxy configuration at the session level. When creating a new browser session through the Browserbase API, specify Hex Proxies credentials in the proxy configuration:

1. Create a Hex Proxies account and purchase a residential or ISP plan.

1. Navigate to the Hex Proxies dashboard and copy your proxy credentials (host, port, username, password).

1. Configure Browserbase session creation to use your Hex Proxies endpoint:

```javascript const session = await browserbase.sessions.create({ projectId: "your-project-id", proxies: [{ type: "http", server: "gate.hexproxies.com:8080", username: "your-username", password: "your-password" }] }); ```

1. All page navigations within the Browserbase session now route through Hex Proxies, appearing as residential or ISP traffic to target websites.

1. For geo-targeted browsing, append country codes to your username (e.g., user-country-us) to route through IPs in specific countries.

1. Monitor proxy performance through the Hex Proxies dashboard alongside Browserbase session metrics.

Setup Guide

1. Sign up at hexproxies.com and fund your wallet -- activation is instant with no waiting period.

1. Select a residential plan for broad AI browsing or ISP plan for session-consistent workflows.

1. Copy your proxy gateway credentials from the dashboard: gate.hexproxies.com:8080 with your username and password.

1. In your Browserbase configuration, add the proxy settings to your session creation parameters.

1. Test the integration by creating a Browserbase session with proxy enabled and navigating to httpbin.org/ip to verify the proxied IP.

1. For production AI agents, implement proxy rotation logic: use per-request rotation for data collection and sticky sessions for authenticated workflows.

1. Monitor success rates and latency through both Hex Proxies and Browserbase dashboards.

Pricing for Browserbase Proxies

Residential proxies start at $4.25 per GB with volume discounts at higher tiers. Browserbase sessions typically consume 50-200 MB per session depending on the pages visited and content loaded. For an AI agent running 1,000 sessions daily averaging 100 MB each, monthly bandwidth is approximately 3 TB at competitive per-GB rates.

ISP proxies are available at $2.50 per proxy per month with unlimited bandwidth -- ideal for Browserbase workflows that reuse the same IP across many sessions. A pool of 25-50 ISP proxies covers most Browserbase use cases with dedicated, consistent IPs.

Both plans include full dashboard access, SOCKS5 support, and geo-targeting capabilities. No hidden fees or bandwidth surcharges.
