I really like how easy it is to integrate Fingerprint. The setup was super simple, just adding a few lines of code, and it was up and running in minutes. The UI is also very simple and helps me quickly access necessary data across months. Fingerprint's device fingerprinting accuracy is impressive and it effectively identifies repeat users, even if cookies are cleared or during incognito browsing. It's great for detecting common user fraud, preventing abuse, and managing multi-account detection with strong signals for fraud prevention. Review collected by and hosted on G2.com.

So it's expensive at scale. There are some time false positives occasionally. And, yeah, mainly these two things. Review collected by and hosted on G2.com.

Its reliable and simple, we do not use all the features, mainly the unique visitor Id, which works well for us, especially for the mobile app users Review collected by and hosted on G2.com.

We have seen it failing to mark same device with same unqiue visitor ID, especially when desktop and mobile web as platformas are involved Review collected by and hosted on G2.com.

What stood out to me with Fingerprint is how easy it was to integrate into our existing stack. The documentation is straightforward, and the setup didn’t feel overly complex or time-consuming. Once we had it running, it’s been pretty hands-off, which is exactly what you want from something like this.

The accuracy has also been solid. We’ve seen very consistent device identification, even across different browsers, which was important for us. The dashboard is clean and easy to navigate, so it doesn’t take much effort to understand what’s happening at a glance.

Support has been another positive. Whenever we’ve reached out with questions, the team responded quickly and with actual helpful guidance — not canned responses. That made a big difference. Review collected by and hosted on G2.com.

Pricing can get a bit expensive as you scale, especially if your traffic increases quickly. It’s not unreasonable, but it’s definitely something to keep an eye on as you grow.

I also think there could be more built-in tools or clearer examples for some edge-case scenarios. The SDK itself works well, but having a few more practical implementation examples or ready-made patterns would make things smoother, especially for more complex setups.

That said, I don’t have any major complaints. Once everything is set up, it runs reliably and doesn’t require much ongoing effort. Review collected by and hosted on G2.com.

I really like Fingerprint's reliability and accuracy in identifying users, which is much more robust than traditional methods like IP addresses or cookies. This gives me confidence that our rate limiting is genuinely effective, crucial for protecting our proprietary data. The setup was straightforward, with smooth integration and clear documentation, allowing us to start using the visitor identification signals right away. I've found it balances strong abuse prevention with a smooth user experience, working seamlessly in the background without adding friction for legitimate users.

Overall, Fingerprint works well for us, but there are a few areas where improvements would add even more value. First, while the identification is strong, having even more visibility and transparency into how confidence scores are derived would help us fine-tune our rate-limiting logic. Deeper analytics or clearer debugging tools would make it easier for our team to investigate edge cases. Second, more built-in tooling around abuse detection patterns or anomaly insights (on top of raw identification) would be helpful. We currently layer additional logic on top, so tighter integrations or native features in that direction could reduce engineering overhead. Review collected by and hosted on G2.com.

The best thing about fingerprint is the suspect score it provides for each user, network and IP details and the unique visitorId it generates. The APIs are well documented, easy to use and integration was smooth. Review collected by and hosted on G2.com.

The visitorId can change when a customer uses a different browser on the same machine. This feels more like a feature request: if it’s possible, it would be helpful to identify the same user across different browsers. Review collected by and hosted on G2.com.

As a data analyst in a performance marketing agency, what I value most about Fingerprint is the reliability of its visitor identification across sessions and devices. In marketing attribution and fraud analysis, traditional cookies are fragile and frequently blocked. Fingerprint provides a much more stable identifier, which significantly improves match rates and reduces ambiguity in our datasets.

We use Fingerprint on a daily basis across multiple client environments, particularly for fraud detection workflows and attribution analysis. Because it becomes part of the core tracking layer, reliability and uptime are critical, and in our experience it has been consistent and dependable.

Customer support has also been responsive and technically competent. When we’ve had implementation or configuration questions, responses were clear and solution-oriented rather than generic documentation links. That makes a difference when you’re integrating into live production environments.

From a data perspective, it reduces noise, strengthens identity resolution, and supports more confident decision-making across fraud rules, campaign optimisation, and reporting.

Integration was straightforward, with clear documentation and flexible API options that made it easy to connect to our existing data pipelines and backend systems without major refactoring. Review collected by and hosted on G2.com.

While the identification accuracy is strong, pricing can scale quickly depending on traffic volume, which may be a consideration for high-traffic campaigns or large e-commerce clients. It requires careful forecasting to avoid unexpected cost increases.

There is also a learning curve when designing fraud rules or risk scoring logic around the fingerprint ID itself. The tool provides the identifier and signals, but building an effective fraud decisioning layer still requires internal data engineering effort.

Finally, communicating fingerprint-based identification to non-technical stakeholders can be challenging, particularly when discussing privacy implications or browser-level limitations. Review collected by and hosted on G2.com.

I truly appreciate Fingerprint for its accuracy and consistency in device identification, even in complex environments. This high-quality intelligence is invaluable, and the ease of integration and monitoring is a significant advantage. The overall developer experience with Fingerprint is exceptional, with smooth integrations and reliable webhooks. The low latency is particularly beneficial, making Fingerprint easy to scale and trust in real-time decision-making workflows. The initial setup was remarkably straightforward, thanks to clear documentation and well-structured SDKs. Fingerprint distinguished itself during our selection process with its accuracy, stability, and ease of integration, making it the clear winner among potential solutions.

I find that the product could improve in its transparency with probabilistic links and handling edge cases. In controlled environments, like internal testing or shared devices, probabilistic associations can create links that are difficult to interpret. Having more clarity or tools to understand why a probabilistic match was created would aid in debugging. Additionally, consistency of data availability across different workspaces can be improved. Sometimes, the same user or device-related information isn't seamlessly shared between environments, which can create blind spots during case analysis. Enhancing the ability to synchronize or reference common data across multiple workspaces - or at least providing clearer guidance or tools for handling those gaps - would streamline investigations and reduce unnecessary switching between environments.

We use Fingerprint in our web application as part of our team to identify users during signup and login. In my work I look at device IDs when new accounts are created to help us reduce duplicate and suspicious signups. This has enabled us to make our onboarding process more secure, without adding friction for users. It also works great without cookies, which has been especially helpful for our platform. The integration was easy and didn’t take a lot of changes to our existing system. Review collected by and hosted on G2.com.

We use Fingerprint to run checks during signup and login in our SaaS web application. As our user traffic grows, the pricing can become expensive. Part of my role is reviewing flagged or repeat devices, and the dashboard isn’t always intuitive, so it often takes extra steps to locate specific details. Simpler navigation, stronger filtering, and more built-in reports would make it easier for us to analyze user activity more quickly. Review collected by and hosted on G2.com.

I didn't think it was possible to collect this information from visitors, although it's a great feature if you have a website or app, as fingerprinting allows you to prevent fraud to a very high degree. Review collected by and hosted on G2.com.
