Why open source matters for search engines

Open source search engines give you full visibility into how your data is processed. Unlike proprietary solutions, you can audit the source code, verify security claims, and ensure there are no hidden data-sharing practices. This transparency is foundational to genuine GDPR compliance.

By choosing open source, you avoid vendor lock-in and retain the freedom to migrate, self-host, or customize the software to your exact needs. For European organizations, this means true data sovereignty — your infrastructure, your rules, no dependency on a single provider's business decisions.
