The Time-Series Database
That Never Forgets

Near disk-speed performance. Perfect version history. Thousands of distributed nodes.

// Never lose data again - every change is versioned
let db = LegionDB::connect("cluster://prod")?;
let stream = db.stream("sensors/temperature");

// Accidentally deleted production data?
stream.rewind_to(Timestamp::minutes_ago(5));

// Query billions of points at disk speed
let results = stream.filter(|point| point.value > 100.0);

Built Different, Built Better

Solving the impossible trade-offs of time-series data

⚡

Disk-Speed Performance

Zero-copy architecture with memory-mapped files. Read and write at the theoretical maximum speed of your storage.

🔄

Perfect Version History

Git-like branching and merging for your data. Travel back to any point in time, compare versions, never lose a change.

🌐

Massively Distributed

Scale to thousands of nodes with selective sync. Each node subscribes only to relevant data streams.

ðŸ“Ķ

Embeddable + Auto-Sync

Deploy at the edge or in the cloud. Embedded instances automatically sync when connected.

🚀

WASM Query Engine

Write queries in any language that compiles to WebAssembly. Type-safe, sandboxed, blazingly fast.

ðŸ›Ąïļ

Never Lose Data

Accidental deletions are reversible. Built-in audit trails. Your data is safe by default.

Performance That Speaks Volumes

Built in Rust for predictable, blazing-fast performance

10Ξs Query Latency
10K+ Distributed Nodes
∞ Version History
0 Data Loss Events
