Basic Proxy Configuration

Use the --proxy flag or set proxy via environment variable:

bash

# Via CLI flag
agent-browser --proxy "http://proxy.example.com:8080" open https://example.com

# Via environment variable
export HTTP_PROXY="http://proxy.example.com:8080"
agent-browser open https://example.com

# HTTPS proxy
export HTTPS_PROXY="https://proxy.example.com:8080"
agent-browser open https://example.com

# Both
export HTTP_PROXY="http://proxy.example.com:8080"
export HTTPS_PROXY="http://proxy.example.com:8080"
agent-browser open https://example.com

Authenticated Proxy

For proxies requiring authentication:

bash

# Include credentials in URL
export HTTP_PROXY="http://username:password@proxy.example.com:8080"
agent-browser open https://example.com

SOCKS Proxy

bash

# SOCKS5 proxy
export ALL_PROXY="socks5://proxy.example.com:1080"
agent-browser open https://example.com

# SOCKS5 with auth
export ALL_PROXY="socks5://user:pass@proxy.example.com:1080"
agent-browser open https://example.com

Proxy Bypass

Skip proxy for specific domains using --proxy-bypass or NO_PROXY:

bash

# Via CLI flag
agent-browser --proxy "http://proxy.example.com:8080" --proxy-bypass "localhost,*.internal.com" open https://example.com

# Via environment variable
export NO_PROXY="localhost,127.0.0.1,.internal.company.com"
agent-browser open https://internal.company.com  # Direct connection
agent-browser open https://external.com          # Via proxy

Common Use Cases

Geo-Location Testing

bash

#!/bin/bash
# Test site from different regions using geo-located proxies

PROXIES=(
    "http://us-proxy.example.com:8080"
    "http://eu-proxy.example.com:8080"
    "http://asia-proxy.example.com:8080"
)

for proxy in "${PROXIES[@]}"; do
    export HTTP_PROXY="$proxy"
    export HTTPS_PROXY="$proxy"

    region=$(echo "$proxy" | grep -oP '^\w+-\w+')
    echo "Testing from: $region"

    agent-browser --session "$region" open https://example.com
    agent-browser --session "$region" screenshot "./screenshots/$region.png"
    agent-browser --session "$region" close
done

Rotating Proxies for Scraping

bash

#!/bin/bash
# Rotate through proxy list to avoid rate limiting

PROXY_LIST=(
    "http://proxy1.example.com:8080"
    "http://proxy2.example.com:8080"
    "http://proxy3.example.com:8080"
)

URLS=(
    "https://site.com/page1"
    "https://site.com/page2"
    "https://site.com/page3"
)

for i in "${!URLS[@]}"; do
    proxy_index=$((i % ${#PROXY_LIST[@]}))
    export HTTP_PROXY="${PROXY_LIST[$proxy_index]}"
    export HTTPS_PROXY="${PROXY_LIST[$proxy_index]}"

    agent-browser open "${URLS[$i]}"
    agent-browser get text body > "output-$i.txt"
    agent-browser close

    sleep 1  # Polite delay
done

Corporate Network Access

bash

#!/bin/bash
# Access internal sites via corporate proxy

export HTTP_PROXY="http://corpproxy.company.com:8080"
export HTTPS_PROXY="http://corpproxy.company.com:8080"
export NO_PROXY="localhost,127.0.0.1,.company.com"

# External sites go through proxy
agent-browser open https://external-vendor.com

# Internal sites bypass proxy
agent-browser open https://intranet.company.com

Verifying Proxy Connection

bash

# Check your apparent IP
agent-browser open https://httpbin.org/ip
agent-browser get text body
# Should show proxy's IP, not your real IP

Troubleshooting

Proxy Connection Failed

bash

# Test proxy connectivity first
curl -x http://proxy.example.com:8080 https://httpbin.org/ip

# Check if proxy requires auth
export HTTP_PROXY="http://user:pass@proxy.example.com:8080"

SSL/TLS Errors Through Proxy

Some proxies perform SSL inspection. If you encounter certificate errors:

bash

# For testing only - not recommended for production
agent-browser open https://example.com --ignore-https-errors

Slow Performance

bash

# Use proxy only when necessary
export NO_PROXY="*.cdn.com,*.static.com"  # Direct CDN access

Best Practices

Use environment variables - Don't hardcode proxy credentials
Set NO_PROXY appropriately - Avoid routing local traffic through proxy
Test proxy before automation - Verify connectivity with simple requests
Handle proxy failures gracefully - Implement retry logic for unstable proxies
Rotate proxies for large scraping jobs - Distribute load and avoid bans
