QuestDB.com is the home of an open-source time-series database built for high-performance workloads like trading, aerospace, and AI. As a SaaS company, QuestDB offers both a free community edition and paid enterprise plans. Legitimate software vendors in this space typically have long domain histories, visible ownership, and proper legal pages—and QuestDB checks all those boxes. Its 26-year-old domain and clean blacklist status put it in the same league as established tech businesses. The site loads a large number of external scripts (20 in total), which is common for a product with interactive demos, analytics, and documentation tools. Still, it's something to be aware of if you're integrating their software into sensitive environments. For most users, there's no reason to question whether QuestDB is a scam or fake; the evidence overwhelmingly points to a real company that has been around for decades. If you're evaluating whether to use their database, their transparent communication and strong security posture are reassuring.
In plain English
QuestDB.com is a legitimate open-source database company with a long history and solid security. The domain is 26 years old, which is a strong trust signal, and the site has clear contact and legal pages. The only minor concern is a high number of external scripts, but that's typical for a modern tech product site and doesn't outweigh the many positive signals.
Where the score comes from
Strong security setup: valid TLS certificate, modern encryption, and multiple browser protections like clickjacking prevention and content security policy. No red flags from Google's threat systems.
The domain has been registered for 26 years, which is a strong sign of a legitimate, established business. Ownership details are visible, and the registrar (Gandi) is reputable.
Clean blacklist status and no malware flags. The site has been archived in the Wayback Machine since 2004, showing a long web presence. No Trustpilot profile is neutral for a company of this size.
About page, contact info, and links to multiple social media platforms are all present. The company openly presents itself and its team, which is good for a tech business.
Privacy policy and terms of service are available. For a SaaS company selling enterprise software, this meets the baseline. No cookie consent banner was flagged, but that's common for US-based tech firms.
Hosted on Netlify with email via Google and strict DMARC. However, the site loads 20 external scripts, which is high. For a database company, this may be analytics and tooling, but it's worth noting as a potential risk vector.
