What are open source analytics tools?
Open source analytics tools are software platforms where the source code is public and modifiable. Unlike proprietary solutions like Google Analytics, these tools allow organizations to own their data entirely, hosting it on their own servers or cloud infrastructure. This ensures maximum data sovereignty and full control over privacy settings.
Why self-host your web analytics in 2026?
Self-hosting analytics has become essential for privacy-conscious brands. It allows for GDPR and CCPA compliance without the need for complex cookie banners in many cases. By eliminating third-party data sharing, you build deeper trust with your users while maintaining fast site performance by using lightweight, purpose-built tracking scripts.
