Hister – A private, full content search index that you control

Hister is a self-hosted, privacy-focused full-text search solution that enables organizations to index and search their internal content while maintaining complete data control and eliminating cloud dependency. For IT leaders, this addresses critical compliance and data governance requirements by providing an auditable, open-source alternative to cloud-based search services with zero telemetry and the ability to run entirely on-premises infrastructure. The platform's flexible deployment options—from local machines to multi-user servers with PostgreSQL—make it strategically valuable for enterprises seeking to reduce vendor lock-in and strengthen data sovereignty.
