growthbook.io Overview

Description of growthbook.io

growthbook.io appears to be the official website for GrowthBook, a software platform focused on experimentation, feature flags, and product analytics. The homepage messaging and metadata describe it as a warehouse-native and open-source product used by product and engineering teams to run A/B tests, manage feature releases, and analyze product performance.

Based on the visible content, the site is operated as a business software service rather than a consumer-facing marketplace. It includes product navigation, documentation, pricing, blog resources, sign-in access, and calls to action such as booking a demo or starting for free. The domain has been registered for several years and presents itself as an established technology company serving organizations that build and optimize digital products.

Safety Assessment for growthbook.io

The available scan data is generally favorable at the time of this scan. No detections were reported by 0 out of 91 security engines, and the domain was shown as clean by the checked malware and phishing blacklist databases. The site also appears to be a legitimate business platform with substantial visibility, supported by its multi-year domain age and relatively strong traffic ranking.

One automated malware scan did produce a low-confidence suspicious result tied to a blog page and an external referenced domain, labeling it as a generic suspicious object rather than identifying a specific malware family. Because this finding was not corroborated by the broader engine consensus or by blacklist databases, it may reflect a heuristic or contextual false positive rather than confirmed harmful activity.

Based on available data, no threats were detected at the time of this scan, though the isolated heuristic flag suggests a small degree of caution is still reasonable when interacting with externally linked content.

Technical Description

The site uses a valid SSL/TLS certificate issued through Amazon infrastructure, with certificate validity extending to late 2026. It is served through Cloudflare and hosted on AWS CloudFront, which is a common content-delivery and edge-hosting setup for established web applications. The observed server IP geolocates to Paris, France, though CDN-based services can distribute traffic globally.

DNSSEC appears to be unsigned, which is not unusual but means DNS responses may not benefit from that additional layer of authenticity protection. No major infrastructure-level security concerns were evident from the provided data, and the domain uses AWS nameservers consistent with managed cloud hosting.
