Alright, I understand objections to Brave's business model, but calling Brave a honeypot is a bit much. Anonymized, aggregated telemetry is enabled by default, but even that can be disabled. All the code is open source.
Although it's growing in age, in Douglas J. Leith's influential academic study, "
Web Browser Privacy: What Do Browsers Say When They Phone Home?", Leith concluded that out of Chrome, Firefox, Safari, Brave, Edge and Yandex—
Brave was the most private browser tested for minimal phoning home. Meanwhile, by default, Firefox sent details of webpages visited to Mozilla's servers and included long-lived identifiers in telemetry transmissions.
A 2025 sizeof.cat independent test compared the unique network connections among fresh installations of browsers. On all default settings, Brave made 17 unique connections right after start:
- Update and component checks (6 domains)
- Anonymized telemetry and usage pings (3 domains)
- Safe browsing and security proxies (2 domains)
- CDNs for asset delivery, AWS and Fastly (6 domains)
Firefox made 29 unique connections:
- Telemetry and data collection with identifiers (2 domains)
- Update and configuration services (6 domains)
- Safe browsing and security, Google (3 domains)
- Push notifications and sync (1 domain)
- Ads and sponsored content (2 domains)
- Add-ons and extensions (2 domains)
- Location and network detection (3 domains)
- CDNs for asset delivery, Akamai and Google Edge (3 domains)
- Normandy, remote‑configuration and experimentation (1 domain)
