Deno KV is a transactional key-value database built into the Deno runtime. The denokv project provides the self-hostable version: a standalone binary, under the MIT license, which you run on a server and to which Deno processes connect via the KV Connect protocol.

Built on the same SQLite backend as Deno's embedded CLI database, the denokv binary is designed to run persistently on a VPS or Kubernetes cluster and handle thousands of concurrent requests from hundreds of different processes. It is ideal whenever multiple instances of an application need to share the same database.

The open-source binary includes continuous backup to S3 or GCS with point-in-time recovery (PITR), and integrates with standard SQLite tooling for replication and maintenance. An ideal solution for modern Deno applications requiring a shared data backend.
