Fully in-process
Single-file storage, WAL + tiered segments, group-commit batching. Copy the file, ship the app.

that syncs.
HakoDB is a Firestore-style document database in Rust. It runs fully in-process like SQLite — no server, no daemon — and replicates over LAN mesh or a cloud hub when you need it.

use hakodb::config::HakoConfig;
use hakodb::engine::Hako;
let db = Hako::open("./data", HakoConfig::default())?;
db.put("users", "alice", &doc)?;
let found = db.query(
Query::new("users").where_filter("age", Operator::Gte, 18.into())
)?;Why HakoDB
The zero-deploy footprint of an embedded engine, with the query power of a document cloud.
Firestore-style queries
Filters, ordering, cursors, projections, count/sum/avg — plus composite, full-text and secondary indexes built in the background.
Zero-copy reads
Projections decode straight from memory-mapped bytes. Dotted-path pulls skip whole-subtree decode — ~18× on nested docs.
Encryption at rest
ChaCha20-Poly1305 over WAL and segments, per-collection keys — with fail-closed sync guards so encrypted rooms never leak plaintext.
Live watch streams
Subscribe to any query; deltas stream over Tauri events, FFI callbacks, or channels. Reactive UIs without polling.
Batches + transactions
Atomic batches and serializable snapshot-isolation transactions with conflict-aware commit validation.
Sync when you need it
Local-first always. Replication is opt-in, per deployment.
Mesh · LAN peers
mDNS + broadcast discovery, room-key isolation, WAL-delta replication across peers. No server on the network.
hakodb · net-sync
Cloud · central hub
Offline-first clients converge through a WebSocket hub: 5 ms micro-batched writes, room-scoped storage, group admission with API keys.
