I use a tool for detecting multi-accounts and bots on my website. It works very well. I previously used the free version, but the paid version is worth it. Thanks to the tool, I’ve saved significantly more than I paid for the service :)

Most importantly, it doesn’t slow down the website.

The website interface is very clear. The implementation is very simple and intuitive. Review collected by and hosted on G2.com.

I really miss having the ability to set a spending limit for the service. Ideally, it should be possible to configure a separate limit for each API key. Review collected by and hosted on G2.com.

Fingerprint has very thorough information on visitor risks, which roll up into their "Suspect Score". We've found it reliable, and correlates with other signals from users. Review collected by and hosted on G2.com.

Some of the initial integrations had documentation that I would like to see a bit clearer. Support did help once I reached out, though. The visitors table in the UI seems to get a filter stuck which is a bit annoying. Review collected by and hosted on G2.com.

I find the accuracy and stability of the visitor identifier in Fingerprint impressive, even across sessions and app reinstalls. The documentation is thorough, making it easier to understand and utilize the product effectively. The confidence score is a genuinely useful signal rather than just a binary flag, providing more nuanced insights. The SDK integration was straightforward, requiring minimal engineering effort to set up. Fingerprint has made our device fingerprinting noticeably more reliable and consistent, with smart signals offering actionable risk indicators without complicating our detection logic.

Nothing major to flag at this stage. However, it would be great if they could uniquely identify users in webviews and custom Chrome tabs (CCT). It would be good to see continued expansion of the smart signals library over time. Review collected by and hosted on G2.com.

Fingerprint.js provides the most value through its reliable device/browser identification and easy integration. We use it regularly as part of fraud prevention and traffic quality analysis, and it helps us better understand whether multiple visits or events are coming from the same user/device even when cookies are limited or unavailable.

One of the biggest benefits is how quickly it can be integrated into a web app. The JavaScript SDK is straightforward, the API is easy to work with, and it fits well into existing frontend tracking or analytics flows. This saves development time compared to building and maintaining our own fingerprinting logic.

Performance has also been good in our use case. It runs on the client side without creating noticeable issues for the user experience, which is important because scripts like this often load on high-traffic pages.

The main ROI is better fraud detection and user recognition. It gives us more confidence when analyzing suspicious behavior, bot-like activity, repeated visits, or users trying to bypass standard cookie-based tracking. That makes it useful not only for security, but also for improving data quality in analytics and marketing workflows.

Support and documentation are also strong. The docs make it clear how to start, how to retrieve visitor IDs, and how to use the results in backend or analytics systems. Overall, it is a reliable and practical tool for identity, fraud prevention, and traffic intelligence. Review collected by and hosted on G2.com.

Fingerprint is very useful, but there are a few areas that could be improved. The pricing can become expensive as traffic volume grows, especially if you need to use it across multiple websites or high-volume environments.

Another limitation is that implementation still requires some technical planning. The basic JavaScript integration is simple, but getting the most value from it requires backend integration, proper event mapping, and clear decisions about how visitor IDs should be used in fraud prevention or analytics workflows.

Also, because fingerprinting depends on browser/device signals, it is not always a perfect identity solution. Privacy tools, browser restrictions, VPNs, and unusual device configurations can still affect accuracy, so it should be used as part of a broader fraud detection system rather than as the only signal.

Overall, I do not dislike the product itself, but I would like more flexible pricing, clearer implementation examples for advanced use cases, and even more transparency around confidence levels and edge cases. Review collected by and hosted on G2.com.

I use it for fraud prevention and multi-accounting detection, plus bot detection on incoming traffic. The stable device identifier lets us recognize the same device even when users clear cookies, switch networks, or browse in incognito mode, and the Smart Signals provide ready to use bot, VPN, and proxy indicators that feed directly into our blocking decisions. Review collected by and hosted on G2.com.

Pricing scales quickly at high volume, so you have to be deliberate about which events actually trigger an identification call instead of firing it on every page load. A few of the newer Smart Signals are only available on higher tiers, and the dashboard could offer better filtering and export for investigating suspicious visitor patterns over longer time windows. Review collected by and hosted on G2.com.

I appreciate the ease of integration with Fingerprint, especially since the SDK is initialized with just a 5-line integration, and there's a simple choice of three regions instead of many confusing ones. I also love the reverse proxy option, which helped us achieve 100% device profile coverage by allowing us to route the DNS traffic for users behind private networks or firewalls. Additionally, the dashboard is great for showing key KPIs and trends, making it easy to monitor vulnerabilities with features like the smart signal. The initial setup was ultra easy thanks to the straightforward documentation. Fingerprint offers a clear view on dashboard regarding usage limits and access management.

Root detection seems very basic. Fingerprint doesn't detect Android's KernelSU level rooting and root hiding techniques. This area can be improved. Review collected by and hosted on G2.com.

Fingerprint is one of the most accurate and privacy-conscious device identification solutions I’ve worked with. Its ability to recognize returning users—even after cookies are cleared or when browsers are in private mode—is especially valuable for fraud prevention and bot mitigation. Implementation is straightforward, the API documentation is clear, and the performance impact is minimal. What stands out most is how well it balances strong identification accuracy with a genuine commitment to transparency and compliance. Overall, it’s a robust option for modern anti-abuse and anti-spam needs. Review collected by and hosted on G2.com.

Because the platform is quite technical, teams without dedicated engineering resources may need extra onboarding time to take full advantage of its capabilities. More advanced configuration and tuning also require some familiarity with fraud detection concepts. Pricing can scale with usage as well, so in high-traffic environments it’s important to plan implementation and monitoring carefully in order to maximize ROI.

Fingerprint.com has continued to be a reliable part of our fraud prevention stack. We run a rewards platform where detecting duplicate accounts, VPNs, and bot traffic is essential. Fingerprint's device identification accuracy remains consistently high, and we've seen very few false positives. The JavaScript agent is lightweight and doesn't noticeably impact page load times. We also appreciate the webhook and server API options, which let us run additional checks server-side before granting rewards. The dashboard has improved over time, making it easier to inspect visitor details and understand flagged signals. Also customer support has been responsive on the rare occasion we've reached out. Review collected by and hosted on G2.com.

The only area I'd love to see improve is pricing flexibility for growing startups. The jump from the free plan to the $99/month Pro tier can feel steep when you're still scaling. A lighter intermediate plan or a pay-as-you-go option would make it easier for smaller teams to grow into the product without hesitation. That said, the value at the Pro tier is solid once you reach the volume to justify it. Review collected by and hosted on G2.com.

I'm a web developer and I've been using Fingerprint for 15 days, both personally and professionally for a client, and it's been excellent so far. Let me tell you how it started.

My client, www.guinrank.com, is a website for writing SEO-optimized articles and much more. They offered a free trial, but

were experiencing excessive use of the free trial on their site. This was costing them a lot in Al API bills and putting a huge

strain on the server. The solution was to find something to stop this, so we used Fingerprint. It offered an unlimited free trial,This was very good for testing the service, and then we integrated it into our login page. We discovered that there were many accounts belonging to the same person, and we blocked them. This helped us solve the problem of the high AI API bill, as it decreased from $900 per month to $500.

Everything was good, but their prices are high and support is slow and not available 24/7. Review collected by and hosted on G2.com.

There are many good features about using Fingerprint, few key points for consideration are -

1. Account abuse:

- Distribution of harmful contents like spam, phishing, CSAI, terror, malware, etc. We want to block these users from creating additional accounts

- Violation of Acceptable Use Policy: we want to drives abusers away from storage abuse, bandwidth abuse, referral abuse, etc.

2. Phishing/spam: Block sharing attempts from known abusers

3. Threat Intel: block account created by known threat actors

4. Payment fraud: block fraud payment attempt for known abusers; block frequent payment attempts for the same fingerprint

5. Users using Dropbox’s API for attacks such as Command and Control (CC) Review collected by and hosted on G2.com.

There might be some privacy and user consent concerns for some users / regions as fingerprint works invisibly behind the scenes, many users don’t know they’re being tracked, but other than this the tool works very effectively. Review collected by and hosted on G2.com.
