Fraud runs on tools: browsers that fake a device, proxies that fake a location, scripts that fake a person. Each tool polishes the layer it controls and leaves contradictions on the others. Here is how Kavra finds them.

- [Antidetect browsers](https://kavralab.com/detect/antidetect-browsers/index.md): Antidetect browsers give one person hundreds of fake devices, each with its own profile and proxy. Learn how they work, who uses them and what gives them away.
- [Residential and mobile proxies](https://kavralab.com/detect/residential-proxies/index.md): Residential and mobile proxies route bots and fraud through real home and carrier IPs. Learn why blocklists miss them and how to detect proxy traffic.
- [VPN and Tor](https://kavralab.com/detect/vpn-and-tor/index.md): VPNs and Tor hide a visitor's real IP for privacy, and sometimes for fraud. Learn how to detect them and treat them as a signal, not a verdict.
- [Headless browsers and automation](https://kavralab.com/detect/headless-browsers/index.md): Headless Chrome, Playwright, Puppeteer, Selenium and stealth plugins drive real browsers at scale. See what gives them away and how to allowlist good automation.
- [Virtual machines](https://kavralab.com/detect/virtual-machines/index.md): Virtual machines and cloud desktops let one operator spin up hundreds of disposable devices. Learn the tells, the legitimate uses and how to avoid false positives.
- [Emulators](https://kavralab.com/detect/emulators/index.md): Android emulators and iOS simulators turn one desktop into dozens of fake phones for app and mobile web abuse. Learn the tells and how to keep real users in.
- [Device farms](https://kavralab.com/detect/device-farms/index.md): Racks of real phones driven by one operator to fake installs, engagement and referrals. Learn how phone farms work and how to link every device back to one farm.
- [Fingerprint spoofing and rotation](https://kavralab.com/detect/fingerprint-spoofing/index.md): Spoofed and rotating device fingerprints make one actor look like a new visitor every time. See how it works and why rotation itself gives the actor away.
- [AI agents](https://kavralab.com/detect/ai-agents/index.md): AI agents browse, compare and buy for real users. Learn how to tell verified agents from unverified ones and impostors, and set allow, check or block per project.
