Libraries

Rust → WebAssembly, sized in single-digit kilobytes. Hover a figure — the plates pull apart.

FlashFuzzy

rust · wasm · ~3 kB · npm: flashfuzzy

Typo-tolerant fuzzy search in about three kilobytes of WebAssembly. Bloom-filter pre-filtering feeds a Bitap matcher — sub-millisecond queries across 100,000-record sets, zero dependencies.

Albex

rust · wasm · webgpu · 13.5 kB

A complete document-search runtime in 13.5 kB of WebAssembly — streaming parsers, accent-insensitive matching, a WebGPU compute pre-filter sweeping 100,000 chunks on the GPU. Documents never leave the machine.

vectis-crdt

rust · wasm · rga/yata · vector clocks

A CRDT for ordered collections of mutable objects — concurrent edits converge without coordination. Replicated sequence, per-property LWW registers, binary wire format, delta sync. Powers SyncInk’s shared canvas.

ClickType

rust · clickhouse

A ClickHouse client for Rust — bulk data ingestion, type-safe query construction, explicit memory control throughout.
