Analyze HAR bytes by domain and resource type in your browser. Compare recordings, expose missing size data and plan a measured proxy bandwidth test.
Open the tool →Check a proxy rotation sample locally. Import timestamped IP observations, separate failures and repeats, and measure changes without claiming an entire pool size.
Open the tool →Convert proxy lists locally between host:port:user:pass, encoded URLs and JSON. Validate ports, IPv6 and credential formats before importing your configuration.
Open the tool →Estimate traffic from a measured pilot. Convert GB and GiB, include failed work and calculate usage cost per valid result.
Plan a traffic budget →Run all 14 tests at once. Complete proxy validation for HTTP, HTTPS, SOCKS5, IPv6, DNS leaks, and performance.
Detect DNS privacy leaks with TCP & UDP testing. Ensure your proxy doesn't expose your real DNS queries.
Discover your public IP with geolocation, ISP details, and VPN/proxy detection. View comprehensive network data.
Validate SOCKS5 authentication and connectivity. Test HTTP, HTTPS, and latency through your SOCKS5 proxy.
Check your proxy anonymity level. Detect Elite (L1), Anonymous (L2), or Transparent (L3) proxies.
Advanced OS fingerprinting via P0F. Detect proxy authenticity with IPv4 and IPv6 passive fingerprinting.
Validate IPv6 support and dual-stack connectivity. Test HTTP, HTTPS, and P0F fingerprinting over IPv6.
Scan any website to detect its anti-bot protection. Identifies Cloudflare, Akamai, DataDome, and 11 more systems.
Build an account username with current country options, explicit sessions and correct rotation behavior. Copy a URL or use the curl, Python and Playwright examples.
Check whether a Mac meets the requirements to supply dedicated AI inference: chip, memory, disk, macOS, Node.js and Python.
Want a second reading? Our partners IPFighter and ToDetect run their own free IP score, fingerprint and leak checks.
