Give your data room to be itself.
Schemaless JSON documents. Collections created on first write. Nested fields, without a migration ceremony.

All the power of a distributed document database.
All the simplicity of a single executable.
Store JSON, query over HTTP, and stream changes in real time. Replication and sharding are already inside.

A whole lot of database.
A whole lot less baggage.
From your first document to your next shard, the hard parts live in the engine. You get to focus on what you’re building.

Change happens.
Be there when it does.
Committed changes over SSE, WebSocket, or signed webhooks. Pick up where you left off with resumable feeds.
Follow the changes ↗03
Simple requests. Serious queries.
Filter nested fields. Add secondary indexes. Sort, paginate, and aggregate across shards through the same HTTP API.

Your writes have a safety net.
A CRC-checked write-ahead log, quorum commits, and automatic leader elections. Choose the write concern your application needs.

Go distributed.
One binary runs a local node, a replica, or a router. Change the configuration as your application grows.
- 01
Replicate for resilience
Leader-driven replication with automatic failover and recovery for replicas that fall behind.
- 02
Shard for room to grow
Distribute keys across groups, migrate online, and merge queries through a router.
- 03
Keep the same protocol
HTTP and JSON, from localhost to your cluster. No external coordinator to install.
Your application HTTP + JSON
DewDB routerRoutes requests to the owning shard
Each shard group replicates and elects its own leader.
