netbear 0.1.3

Browser-observed web intelligence platform

NetBear

NetBear is a browser-observed web exposure intelligence platform for authorized security testing. It uses Playwright-driven crawling to observe pages, requests, responses, JavaScript assets, forms, headers, and generated artifacts so testers can understand a target's exposed surface before deeper manual validation.

NetBear is intended for systems you own or have explicit permission to test.

What NetBear Does

• Crawls web applications with a real Chromium browser.
• Reuses authenticated browser state for logged-in scans.
• Enforces target scope rules before scanning.
• Captures HAR, cURL replay files, screenshots, JavaScript, JSON/XHR responses, fingerprints, and crawl summaries.
• Extracts links, forms, GET parameters, endpoint literals, DOM XSS sink hints, auth storage patterns, and backend fingerprint signals.
• Can run Nuclei after crawling when the external nuclei binary is available.
• Provides CLI commands for local scans and generated artifacts.
• Holds the local API/dashboard entrypoint back while the UI is refactored.

Installation

Install from PyPI:

python -m pip install netbear
python -m playwright install chromium
netbear-check

Install from PyPI when validating pre-release builds:

python -m pip install --index-url https://pypi.org/simple/ --extra-index-url https://pypi.org/simple/ netbear
python -m playwright install chromium
netbear-check

Installation from PyPI :

python -m pip install --upgrade pip setuptools wheel
python -m pip install netbear
python -m playwright install chromium
netbear-check

Installation from PyPI (pre-release validation):

python -m pip install --upgrade pip setuptools wheel
python -m pip install --index-url https://pypi.org/simple/ --extra-index-url https://pypi.org/simple/ netbear
python -m playwright install chromium
netbear-check

Quick Start

Create starter target and scope files:

netbear-init --targets targets.txt --scopes scopes.txt

Edit both files before scanning. targets.txt should contain URLs you are authorized to test. scopes.txt should contain the domains or wildcard domains NetBear is allowed to crawl.

Run a dry run first:

netbear-crawl --targets targets.txt --scopes scopes.txt --dry-run

Run a browser crawl without Nuclei:

netbear-crawl --targets targets.txt --scopes scopes.txt --no-nuclei

List recent crawl runs:

netbear-runs

Inspect the latest run's artifacts:

netbear-artifacts --run latest
netbear-artifacts --run latest --show summary
netbear-artifacts --run latest --show curl-summary

Preview safe replay confirmations from filtered crawl requests:

netbear-replay --run latest
netbear-replay --run latest --limit 20

Send the selected safe replay requests only when you are authorized:

netbear-replay --run latest --execute

Limit crawl size while testing:

netbear-crawl --targets targets.txt --scopes scopes.txt --max-depth 2 --max-pages 15 --delay 1.5 --no-nuclei

The netbear-api and netbear-worker commands are currently present for compatibility, but they exit with clear messages instead of starting the unfinished API/dashboard queue path.

CLI Commands

netbear commands
netbear help netbear-crawl
netbear-check
netbear-init --help
netbear-crawl --help
netbear-runs --help
netbear-artifacts --help
netbear-replay --help
netbear-worker --help

Common Environment Variables

• NETBEAR_TARGETS_FILE: default target file for CLI crawls.
• NETBEAR_SCOPES_FILE: default scope file for CLI crawls.
• NETBEAR_MAX_DEPTH: crawl depth limit.
• NETBEAR_MAX_PAGES_PER_DOMAIN: page limit per domain.
• NETBEAR_RATE_LIMIT_SEC: delay between requests/actions.
• NETBEAR_REPORTS_DIR: output directory for generated reports.
• NETBEAR_NUCLEI_ENABLED: enable or disable Nuclei integration.
• NETBEAR_NUCLEI_RUN_AFTER_CRAWL: run Nuclei after crawl completion.

Outputs

NetBear writes run artifacts under the configured reports directory. Typical outputs include:

• CRAWL_SUMMARY.txt
• report.txt
• HAR exports
• full and filtered cURL replay scripts
• captured JavaScript files
• captured JSON/XHR files
• screenshots
• backend fingerprint JSON
• JavaScript structure JSON
• optional Playwright traces
• generated fuzzing guidance
