Intelligence
The page presents a professional SaaS landing page for GrowthBook, an open-source platform for feature flags and A/B testing. Our antivirus network returned zero detections across 92 engines and the hosting IP carries no abuse reports. The domain has been active since 2020, the company is registered in Delaware and California with active status, and independent review sites show 4.6-star ratings from verified users. The only flagged signal is a template match for crypto-only checkout, yet the site itself offers standard demo and free-tier buttons with no crypto payment flow visible. Business filings, funding history, and GitHub presence all align with a real operating company rather than a throwaway operation.

What to do
Still, stay alert
No major threat indicators — but a clean scan does not guarantee every page is safe, and phishing emails routinely spoof real domains.
- Double-check the exact URL in your address bar
Confirm you are actually on growthbook.io and not a lookalike like g-rowthbook.io.com or an IDN homoglyph.
- Use a password manager
Password managers only auto-fill on the exact domain they were saved for — they refuse to fill lookalike domains, which is the single best phishing defence.
- OpenDiscuss this site on the forum
If you have first-hand experience with this site — good or bad — share it with the MalwareTips community.
Final Verdict
GrowthBook is a legitimate open-source platform for feature flags, experimentation, and product analytics. The domain shows clean scans, active US business registration, and positive reviews on independent sites.
