Hi everyone, we are very excited to be launching our free plan on Product Hunt! FingerprintJS started 6 years ago as an open source browser fingerprinting project which has grown to over 13K stars on Github. We have since built a paid product, FingerprintJS Pro, and raised over $12 million in funding. However, as a developer and open-source first company, we wanted to get back to our roots and make it as easy as possible for individual engineers to explore our product. That's why we decided to launch a 100% free forever plan of our FingerprintJS Pro service. Whether you are working on a personal project or an anti-fraud solution for your day job, we hope our free tier will make accurate visitor identification more accessible for all. --- How Does FingerprintJS Pro Prevent Fraud? --- A small percentage of traffic accounts for the lion's share of online fraud. Whether these individuals (or bots) are cracking login credentials, making purchases on stolen credit cards, or harassing others, the key to preventing their behavior is accurate visitor identification. FingerprintJS Pro assigns each visitor to your website a 99.5% accurate visitorID that remains stable even through incognito browsing, clearing cookies, or using a VPN. By identifying traffic with a pattern of fraudulent activity, you can flag these visitors and take action before they can cause more damage. --- Why We're #1 For Developers --- FingerprintJS Pro is designed for developer teams to build anti-fraud protection into their existing workflows with our API and webhooks. It is flexible and un-opinionated; whatever your fraud use case, you can use FingerprintJS Pro to identify and flag offending traffic. As browser privacy settings change and fraudsters find new ways to conceal themselves, developer teams using FingerprintJS Pro do not need to build deep expertise in browser fingerprinting and server-side identification to protect their websites. They can instead leave visitor identification to us and instead focus on building excellent experiences for their visitors. --- Ask Me Anything! --- That's enough wall of text for now. Would love to answer any questions you might have about FingerprintJS Pro - ask away!
