In-use encryption • Strict regulatory compliance
Built-in AI and Vector Search
Build AI agents and native semantic search without paying for extra subscriptions or orchestrating third-party services.
Native HNSW vectors • Savings on add-on licences
Sovereignty and licence freedom
Forget restrictive SSPL clauses. Full control of your data in your own cloud or private infrastructure with no commercial lock-in.
Permissive open source • Data sovereignty

Radical operational simplicity: from complex clusters to a unified architecture
Traditional solutions need coordinators, balancers and several independent services that drive up maintenance costs. TeselaDB consolidates everything into autonomous high-performance nodes.
Drastic TCO reduction: Up to 60% less server spend by removing redundant intermediate processes.
Zero downtime: Dynamic load rebalancing without interrupting your users' operations or your sales.
Operational peace of mind: Built for agile teams who would rather focus on their business than on managing database complexity.
