IPFighter

Key features of IPFighter:

- IP Lookup & IP Reputation: Check any IPv4 or IPv6 address for detailed information such as geolocation, ISP, ASN, connection type, proxy/VPN/datacenter detection, blacklist status, and reputation score. IPFighter also provides IP scoring to help users evaluate the quality and trustworthiness of an IP.
- Browser Fingerprint: Analyze browser and device signals that websites can use to identify a browser, including User-Agent, screen properties, hardware information, language, timezone, Canvas, WebGL, Audio, Fonts, browser APIs, storage, connection data, and other fingerprint signals. The tool also helps identify inconsistencies and potential automation indicators.
- Bot Detection: Run 50+ browser-based checks to detect automation frameworks, WebDriver, headless environments, DevTools, API tampering, and other signals commonly associated with automated browsers. All checks run locally in the browser.
- Free Web Proxy: Browse websites through residential IP addresses without installing software or creating an account. Users can select a proxy location and optionally enable WebRTC protection and timezone and language spoofing to better align browser signals with the selected proxy connection.
- Proxy Checker: Test HTTP, HTTPS, SOCKS4, and SOCKS5 proxies to check their availability, response speed, exit IP, location, and anonymity level.
- DNS Leak Test: Check whether DNS requests reveal information about the user's actual network or ISP when using a VPN or proxy.
- WebRTC Leak Test: Detect whether WebRTC can expose the user's real IP address through the browser.
- Proxy Manager Extension: Manage and switch proxy connections directly from the browser using the IPFighter extension.
- Coupons & Deals: Discover exclusive promo codes and offers from leading providers across proxy, VPN, antidetect browser, and other related technology services, helping users reduce costs when choosing online tools.

All core diagnostic tools are available for free, with no sign-up required. By bringing IP intelligence, browser fingerprint analysis, bot detection, proxy testing, privacy leak checks, web proxy access, and browser proxy management together in one platform, IPFighter helps users better understand and verify their digital environment.
