Synopsis

List network requests captured during the current session with powerful filtering capabilities using Chrome DevTools filter syntax. 
bdg network list [options]

​
Description

The network list command displays all HTTP requests captured during the active session. It supports DevTools-compatible filter DSL for precise query control, predefined filter presets for common use cases, and resource type filtering. By default, shows the last 100 requests. Use --last 0 to show all requests.

​
Options

​
--json
flag
Output results in JSON format for programmatic consumption.
​
--filter
string
Filter requests using DevTools DSL syntax. Supports domain matching, status codes, HTTP methods, MIME types, size thresholds, and more.Examples:
  • status-code:>=400 - Failed requests
  • domain:api.* - Requests to API domains (wildcards supported)
  • method:POST - POST requests only
  • larger-than:1MB - Responses over 1MB
  • !domain:cdn.* - Exclude CDN requests (use ! for negation)
​
--preset
string
Use a predefined filter preset. Available presets:
  • errors - Failed requests (4xx and 5xx status codes)
  • api - API requests (XHR and Fetch)
  • large - Large responses (>1MB)
  • cached - Cached responses
  • documents - HTML documents only
  • media - Images, video, and audio
  • scripts - JavaScript files
  • pending - In-progress requests (no response yet)
​
--type
string
Filter by resource type. Comma-separated list of CDP resource types: Document, XHR, Fetch, Script, Stylesheet, Image, Media, Font, OtherExample: --type XHR,Fetch
​
--last
number
default:"100"
Show last N requests. Set to 0 to show all requests. Range: 0-10000.
​
-f, --follow
flag
Stream network requests in real-time (updates every second). Shows last 50 requests. Press Ctrl+C to stop.
​
-v, --verbose
flag
Show full URLs and additional details instead of truncated output.

​
Filter Syntax

The --filter option uses Chrome DevTools filter DSL syntax:

​
Status Codes

status-code:404          # Exact match
status-code:>=400        # Comparison operators: =, >=, <=, >, <

​
Domain Matching

domain:api.example.com   # Exact match
domain:api.*             # Wildcard patterns

​
HTTP Methods

method:POST              # Case-insensitive

​
MIME Types

mime-type:application/json
mime-type:text/html

​
Resource Types

resource-type:XHR,Fetch  # Comma-separated list

​
Size Filters

larger-than:100KB        # Supports B, KB, MB, GB
larger-than:>=1MB        # With comparison operators

​
Header Inspection

has-response-header:set-cookie

​
State Filters

is:from-cache            # Cached responses
is:running               # In-progress requests

​
URL Scheme

scheme:https

​
Negation

!domain:cdn.*                    # Exclude matching requests
--filter="!method:POST"          # Use quotes with CLI

​
Multiple Filters

# Combine multiple filters (AND logic)
--filter="domain:api.* status-code:>=400"

​
Output Format

​
Human-readable (default)

Examples

​
List all requests

bdg network list --last 0

​
Find failed requests

​
Tips

Performance: When working with many requests, use filters to reduce output size. The --last option limits display but doesn’t affect filtering logic - filters are applied to all requests first, then --last limits the display.
Preset + Filter: You can combine --preset with --filter to build on existing presets:
bdg network list --preset api --filter "domain:api.internal.*"
Negation Syntax: Use ! for negation instead of - to avoid conflicts with CLI flags. If needed, use quotes: --filter="-domain:cdn.*"
The --follow mode shows the last 50 requests and updates every second. For high-traffic sites, you may miss requests between updates.
