What is Fingerprint?

Fingerprint is a content detector tool. Fingerprint identifies anonymous web and mobile visitors with a device intelligence API, pairing a stable visitor ID and suspect score with Smart Signals such as VPN, incognito, and tampering detection. It is aimed at fraud and engineering teams fighting account takeover, payment fraud, and bot traffic.

Fingerprint is a device intelligence platform built to recognize every visitor that reaches a website or mobile app, including people who never log in. Its core promise is identification that holds up even when someone uses incognito mode, a VPN, or a tampered browser, which is the situation where cookie-based and simple fingerprinting approaches tend to fall apart. The system assigns a stable visitor ID and layers a suspect score on top, so a team can separate accounts worth trusting from traffic worth investigating. In practice, the product is consumed as an API and a set of client libraries. A developer drops the JavaScript or React agent into a web app, or one of the iOS, Android, or Flutter SDKs into a mobile app, and the service returns a visitor ID plus a bundle of Smart Signals. Those signals cover more than one hundred attributes, from geolocation and VPN use to incognito detection and browser tampering, and they arrive in real time so they can drive a decision inside a login, checkout, or signup flow. The same signals feed the platform's main jobs: account takeover prevention, payment fraud reduction, SMS pumping and SIM swap defense, and bot detection. A separate AI agent detection layer uses Web Bot Auth cryptographic signing to tell a verified agent from a spoofed one, so well-behaved automation can be allowed through while malicious automation is blocked. The audience is mainly engineering and risk teams at companies with meaningful fraud exposure: fintech, marketplaces, travel, and any product where fake accounts or card testing cause real losses. Fingerprint also markets the friction side of the equation, arguing that confident identification of logged-out users lets a team reduce two-factor prompts and one-time codes for people it already recognizes. Competitively, it sits alongside other device fingerprinting and bot management vendors, with the open-source FingerprintJS library as a common entry point and an unusually broad server SDK list (Java, Python, Go, Node, Next.js and more) as a differentiator for backend-heavy shops. Pricing is not published on the homepage, so commercial terms have to be requested from sales.

How do you use Fingerprint?

  1. 1Request an API key
    Create a dashboard account to obtain the API key that authenticates calls to the device intelligence service.
  2. 2Follow the quick start guide
    Work through the quick start to understand how the agent loads and where the visitor ID is returned in the response payload.
  3. 3Install the client SDK for your stack
    Pick the matching guide, such as React for a web front end or iOS and Android for mobile, and add the agent to your app.
  4. 4Review the Smart Signals you plan to use
    Read the Smart Signals introduction to see which attributes (VPN, incognito, tampering, bot type) map to your risk rules.
  5. 5Study a use case tutorial
    Use the use case tutorials to assemble a working flow for account takeover, payment fraud, or bot detection, then adapt the thresholds to your own traffic.

Pros and cons

Pros

  • Identifies visitors even under incognito mode, VPN use, or a tampered browser, which is where cookie-based tracking failsAI
  • Smart Signals bundle over one hundred attributes, covering geolocation, VPN, incognito, and browser tampering in one responseAI
  • Broad SDK coverage across JavaScript, React, Next.js, Vue, Svelte, Angular, iOS, Android, Flutter, and multiple server languagesAI
  • AI agent detection uses Web Bot Auth signing to separate verified agents like ChatGPT Agent from spoofed onesAI
  • Backed by a widely adopted open-source library, with 28K+ GitHub stars and 6.7M monthly downloadsAI

Cons

  • No pricing is published on the homepage, so cost has to be established through a sales conversation before budgetingAI
  • The product assumes engineering capacity: SDK installation and signal handling are developer work, not a no-code setupAI
  • Accuracy claims come from vendor and customer material, and teams in regulated markets still need to validate results against their own trafficAI
  • Heavy fingerprinting and device signals can raise privacy and consent questions that legal teams will want reviewedAI
  • The homepage centers on fraud and bot use cases, so teams wanting general analytics or marketing attribution may find it a poor fitAI
