Open Source
We build on open source and contribute back with focused, performance-first libraries.
@addmaple/parquet-liteParquet · WASM
Rust + WASM Parquet reader/writer with typed-array support and snappy compression—lightweight but built for large columnar datasets.
@addmaple/base64-simdSIMD · base64
SIMD-accelerated base64 for Node and browsers. Tight inner loops keep encode/decode fast in data-heavy paths.
@addmaple/statsStats · JS/WASM
Fast statistical primitives for JS/WASM: streaming aggregates, quantiles, and summaries that stay accurate on big data.
@addmaple/wasm-fast-compressCompression · WASM
Lightweight WASM compression helpers tuned for bundle size and throughput when moving data across the wire or into storage.
What we build on
- Web platform: Next.js, React, Headless UI, Vercel Analytics.
- Data + viz: Vega/Vega-Lite, D3, ECharts, csv-parse/stringify.
- Storage + ORM: Drizzle ORM, better-sqlite3.
- Validation + state: Zod/Valibot, Redux Toolkit, SWR, Ramda.
We upstream fixes when we hit edge cases and publish tools that can help others. Contact opensource@addmaple.com if you’d like to collaborate.
